Tecnopol and Sustainable Construction

According to the report, 'Emissions from Building and Infrastructure Consumption', published by C40 Cities, Arup and the University of Leeds, the construction industry could reduce emissions in a 44% by 2050, and for this reason six key areas are carried through reduce the climate impact of construction in cities. However, from Tecnopol we have been working on different aspects for some time now. The company manages the waste internally, by separating recyclable materials, the need for water during the manufacturing processes is minimal, and the water needed is reused through a closed circuit. But where our commitment to make construction more sustainable globally can really be seen is in the achieved characteristics in two of our main products, Tecnofoam and Tecnocoat: Tecnofoam (thermal insulation): Use of polyurethane foams for thermal insulation without greenhouse gases, using water as an expansive agent, without negative effects on the environment. What this generates is that they are completely stable and inert once applied, without emission of particles during their useful life. Moreover, at the time of removal, it is recyclable material without the need for special actions.   Tecnocoat: Pure polyurea membrane solvent free, zero VOC. (With zero emissions of dangerous substances to the atmosphere). Green Label certified system in Singapore and in process in other locations. In conclusion, it is rewarding to create sustainable products; we all need to check I which areas and aspects we can improve and adapt us to reduce the climate impact of construction.


Interview with David Pont, Technical Manager of Tecnopol

David Pont has been a technical architect since 1997, year in which he graduated and started his profession, as a project manager and facultative direction of different projects. Since 2011 he brings his experience to Tecnopol, being his technical director and the maximum responsible of a vital department for the evolution and the daily activity of the benchmark company in the manufacture of Polyurea in Europe, with an important presence worldwide, and which also stands out as a producer of other products, like Polyurethane and Industrial Pavements.   How is Tecnopol’s technical service structured? It is proposed as a consultation service to architects, applicators and in general, to any agent involved in the process of design, planification and execution of construction projects, who would be interested in the systems and products that we develop and manufacture. Our main objective is to support the prescriber in all phases, from our laboratory, in the office and on site. Thanks to my previous experience, I try to visualize and involve myself in each project globally and not only in the aspects related to waterproofing: the key is to always seek to help the prescriber in the sustainability of the project. The technical service gets involved from the initial phase of the projects? Yes, whenever they require our collaboration. The appearance of the Tecnopol brand in the project specifications is an added guarantee for all those who are part of the evolution of the project and its subsequent maintenance. This has allowed us to be present in important private projects in countries such as Chile, Argentina or the Dominican Republic, as well as in other public projects in India (Metropolitan train project in Delhi, civil infrastructure works in Vietnam, Grand Memorial of Bharatratna Dr. Babasaheb Ambedkar...).Providing knowledge of the properties and application of our liquid waterproofing systems and, at the same time, give solutions to different finishing possibilities and aesthetic definitions, are key elements for achieving an optimum final result and optimising costs, correctly applying the appropriate quantities of each product.  The choice of construction solutions is normally defined in the consulting phase during the design of the project and from the R+D department, we always try to give the appropriate answer to each request made to us.  Training for Applicators is also an important issue. Is it difficult to apply Tecnopol products?  They're not difficult to apply at all. It is simply necessary to understand simple chemical processes and at the same time, be careful with the maintenance of the different application equipment. It is essential to provide, for our entire team, initial and ongoing training in the application processes of our solutions and the products that make them up. All of this complemented by the service to all kinds of specific queries that reach us from anywhere in the globe thanks to the Internet and messaging systems.  Your systems and products are used in all kind of building and projects. Is it different the advice requested if it comes from an architect, engineer or applicator?  It is clear that each agent involved in the construction process has different visions, needs and interests regarding the same concept, and in this field of waterproofing is no different. Doubts that may arise in the project phase don’t need to be the same as during the implementation phase. In this sense, all the technical department team know how to proceed in each case. Standards and certifications change, depending on the country. How do you cope with the dispersal of requirements? Important question. Globalization has allowed us to have presence very fast in international markets, and as there is no other way, constructive tradition, meteorology or simply each country’s culture makes the national and local building regulation different. This is why, in many countries the certifications or tests carried out can be analogous to those of other countries of different continents.  Therefore, we have more than 100 certifications, tests or approvals worldwide (ETE, BBA, AVIS TECHNIQUE, ASTM, Green Label ...). All of this added to our territorial implantation in more than 50 countries all over the world gives us the capacity to cover the needs of local homologation and in this way, to be able to access the public and private tenders of projects in competition. Specifically, and in order to offer some data that may be representative of this, we are a reference company with homologated waterproofing and thermal insulation systems in public tenders in some Middle East countries or in important oil corporations in the global area. In the case of Europe, a great deal of harmonization has been done since the creation of the "EOTA" organization, institution creator of the standards that affect construction at a European level, and the CE marking standard. Even so, there are local certifications that are restrictive to the standards issued by EOTA. In addition, the territories affected by earthquakes, volcanoes, hurricanes, and more recently by the effects of climate change, force to take more and more factors into account. How does all this affect their work?  Climate change has a clear reflection, without going any further, in the Mediterranean area where we are located, it has affected meteorology with the appearance of precipitations of less predictable rains, more intense and located in a shorter temporal space. Consequently, waterproofing has to be optimised taking these new factors into consideration. In other areas of the globe, effects such as El Niño or La Niña (I am thinking about the American continent), represent important tests for our systems, which demonstrate day by day, and in front of each new challenge their effectiveness and watertightness. Does your work have a direct impact on the economic and environmental sustainability of the projects in which you collaborate? Taking into account the properties of some of our systems, especially in the field of thermal insulation, yes. Continuous systems with these types of properties have a direct impact on the daily energy consumption of industrial, commercial or residential buildings. The use on the other hand of materials (such as Tecnofoam polyurethanes) without fluorinated gas content, a source of the greenhouse effect and the effect on the ozone layer, are an important asset and their choice is an important criterion when prescribing a thermal insulation system. How do you imagine the future of construction? No doubt, the inclusion of the concept of "environmental sustainability" is going to influence the appearance of new products and therefore in the way and manner of building, in fact, it is already doing so: the way they are manufactured, how they positively affect the reduction of energy consumption of buildings, and the affectation or necessary recycling processes at the time of being withdrawn are parameters that are going to affect the way of understanding the construction, its execution and its particular use. It is necessary to be able to offer the public and final user of buildings, a product where the relationship between "cost, quality and sustainability" is optimal, due to the impact that the processes of implementation, use and after-sales can have on the climate change of the planet. Consequently, all of us will have to adapt and be able to offer products under new and different standards from those learned in universities or already applied and prescribed according to our previous experience.


The importance of Polyurea in the coverage of Sant’s railways box

Thanks to the Tecnocoat system of Tecnopol a safe waterproofing was achieved by means of a single layer The district of Sants in the city of Barcelona underwent/suffered an important urban change because of the creation of the station Barcelona Sants. It is currently the second-largest railway station in Spain, with some thirty million passengers a year, a third of whom make long-distance journeys. The successive improvement works since its inauguration in 1979, and the adaptation to high-speed trains, have progressively changed both the station and its urban environment; one of the most visible changes was produced by the burying in 2007 of the tracks that ran in a south-west direction with respect to the station, creating an insurmountable artificial barrier that crossed the neighbourhood. In order to resolve the space as a whole, an enormous concrete block / box was built over the train tracks that divided the neighbourhood, giving rise to a large 800-metre-long landscaped pedestrian area. With this urban development, the neighbourhood has been organised internally, communicated and opened to the public use of the neighbours and the city in general. Project features The project includes the community use of the upper part by means of paved areas and green zones; while in the interior zone numerous passages coexist with complex canalizations and the passage of communications facilities. In other words, the coverage action is used to grant pleasant spaces for daily use for the population and, at the same time, to optimise the urban communications that coexist at present. As a constructive solution for waterproofing under the pavements, Tecnopol's tecnocoat system was chosen (made with pure polyurea Tecnocoat P-2049); with three objectives: to achieve a complete and safe watertightness of the concrete slab, to reduce the overall execution time and to make it possible to carry out subsequent civil works on the same polyurea membrane without the need for heavy protection, with maximum safety in terms of resistance to abrasion, punching and direct circulation. Technical characteristics of the system The substrate was prepared by milling/polishing the reinforced concrete with special intensive polishing equipment to give a visual finish to the "Concrete Surface Profile CSP-2" scale. This substrate preparation action, together with the application of a polyurethane resin as a primer-sealant, made easier the subsequent application of the polyurea membrane avoiding the appearance of pinholes or other pathologies, ensuring a good continuous adherence to the substrate. Hot spraying provides greater security to the watertightness of the whole as the control of the mixture of the two liquid products required is carried out through a fully digitalised mixing equipment, which controls the mixing ratios, temperatures and pressures suitable for its solid formation. After pre-treatment of the surface, two intercrossed layers of 100% polyurethane resin "PRIMER PU-1050 solids" were applied; and then the "TECNOCOAT P-2049 pure polyurea membrane" was applied, with an average thickness of 2 mm, continuously without overlaps or joints and completely adhered to the concrete. A general application was carried out on the entire surface of the concrete slab, and also in specific areas of encounter with perimeter walls, channelling, metal finishes or concrete boxes for the passage of installations. The membrane was completely covered by pavements and gardens, that is, without exposure to UV rays, and given the magnitude of the project, different finishes coexist: ceramic pavements, granites, mortars, children's play areas, gardens, etc. Summarizing the advantages of the choice of this system highlight the direct and rapid application, drying in seconds that facilitates the application of large surfaces with high labor outputs, continuous training, without overlaps or joints, which reduces the possibility of seepage. Creation of a single, direct layer, with 100% safe waterproofing. Absence of mortar slopes for the evacuation of water (applied directly to the structural element which increases its adherence and protection against water ingress). Great resistance to abrasion, punching and rolling, which means that its passability during the execution of masonry works can be carried out without the need for protection by means of traditional concrete layers. Finally, it is a system with numerous certifications, approvals and tests worldwide (ETE, BBA, ASTM, ISO) which ensures and demonstrates its effectiveness; and its great versatility in many areas of work where it can be applied, both in terms of meteorology, construction methods or design and final use.


TECNOFOAM G-2060 Foam designed for insulation of transitable inverted roofs.

Excellent properties We have extended our range of polyurethane foams with the inclusion of the new TECNOFOAM G-2060, a foam specifically formulated for the application and formation of high density polyurethane foam (±52~62 kg/m³).  This new foam replaces the previous TECNOFOAM G-2050 which has now been withdrawn from our catalogue. All the tests conducted with the new TECNOFOAM G-2060 have produced even better results than its predecessor, making it ideal for inverted roof systems in combination with TECNOCOAT P-2049 polyurea.  TECNOFOAM G-2060 is a completely closed cell foam, a composition which directly influences its fundamental properties, such as thermal conductivity, absorption and waterproofing, permeability to water vapour, dimensional stability and resistance to compression.      A system suitable for all roof surfaces  Roofs which use a system with a high density and resistance to compression are normally considered transitable. In the TECNOFOAM G-2060 + TECNOCOAT P-2049 system, the high compression resistance of the polyurethane foam, the formation of a regular surface thanks to “closed cell” nature, together with the high resistance of the polyurea, allow the creation of a system which is ideal even for vehicle traffic purposes.   It is also a system widely used in all types of roofs (inclined or otherwise) with insulation and waterproofing requirements: roofs for farms, industrial warehouses, shopping centers, etc.  TECNOFOAM G-2060 allows the application of a polyurea membrane over its exterior coat in a continuous form without the risk of “pinholes” or bubbles forming.   GENERAL FEATURES TECNOFOAM G-2060 is a product with high insulating capacity, easy to apply covering all surfaces. The application and formation of the foam are carried out means a spray equipment. It is specially designed to be coated with TECNOCOAT P-2049, without the appearance of bubbles, “pinholes” or other pathologies. It does not emit any substance to the environment once installed. The properties of this polyurethane foam system allow it to adhere to any surface such as concrete, ceramic, metal, polyurethane foam, wood, acrylic paints (checking the situation of areas recommended). The application of TECNOFOAM G-2060 is completely continuous, instead of the classic non-continuous thermal insulation material , saving any kind of union between applications, and providing a optimum thermal insulation  surface with high thermal insulation parameters TECNOFOAM G-2060, is under european norme EN 14315-1:2013, thermal insulation products for buildings, in situ formed sprayed rigid polyurethane (PUR) It has CE mark on the basis of a declaration of performance DoP prepared in accordance with EU regulation 305/2011. or statement available on demand.   MORE INFORMATION ABOUT TECNOFOAM G-2060      


Moisture in concrete and coatings sensitive to damp.

Slabs of concrete are the system most used in the construction of all types of buildings and the use of concrete walls is ever more common. Sometimes the concrete surface may be left as a decorative feature in itself, while on other occasions it may be decided to cover it with coatings and finishes.   For the correct application of coatings sensitive to damp (including adhesives) an understanding is required of the source of the moisture within the concrete, the variations in damp during drying time, the factors which affect drying and the drying point after which coatings sensitive to damp may be applied.   We will go on to present a brief summary of how to determine the moisture content in concrete and how to interpret the information in order to obtain a realistic indication of whether the concrete drying point is suitable for applying the finishes.  The total degree of moisture within the concrete, whether water or water vapour, is known as the “moisture content” and is generally expressed as a percentage of the mass of the concrete.     Moisture may exist in the form of water (when the concrete is damp and the pores are saturated) or as water vapour. The amount of water vapour, and thereby the relative moisture within the concrete, varies significantly with time, depending on the degree of water vapour which entering or escaping from the concrete.  It is important to bear in mind that due to the minuscule capillaries of concrete, it may be almost saturated with water and yet have a moisture content of just 5%.  This has implications for what is considered a “sufficiently dry” concrete surface.   READ HERE THE ENTIRE ARTICLE 



PRIMER WET obtains the UNE-EN 1504-2:2005 certification (principle 1.2 protection against penetration) as a product suitable for use on concrete structures The UNE-EN 1504.2 standard entitled “Products and systems for the protection and repair of concrete structure” is the European approval certificate which defines the identification, performance (including durability aspects), safety and assessment of conformity for products and systems designed for concrete surface protection, with the purpose of increasing the durability of concrete and reinforced concrete structures, in both new concrete constructions and maintenance and repair work.    Recently our 100% solid resin for very damp surfaces PRIMER WET has successfully passed all the tests conducted by the  TECNALIA laboratories,  obtaining the  EN 1504-2:2005 (principle 1.2 protection against penetration). The results of these tests and a copy of the certification are available on request from our technical department.   PRIMER WET is an epoxy resin without solvents, of low viscosity, applicable in one coat. It is especially designed to increase the adherence of our waterproofing systems based on continuous membranes, TECNOCOAT P-2049, pure polyurea membrane, and DESMOPOL, polyurethane membrane, on concrete or mortar surfaces with high residual moisture of up to 98%. PRIMER WET obtains the UNE-EN ISO 7783-1:2000 standard In conjunction with the above certification, the tests and trials required under the UNE-EN ISO 7783-1:2000 standard were performed by the TECNALIA laboratories, under the title “Determination of the water vapour transmission rate according to the dish method for small films.”, obtaining the highest results (45.57 SD(m) ± 2,74) for a  Class II certification, very close to Class III, impermeable to water vapour.

TECNOCOAT P-2049 obtains the suitability certificate for use in CONTACT WITH DRINKING WATER

In accordance with BS6920 issued by the NSF laboratories The UK standard WRAS BS 6920 is defined as the "Suitability of non-metallic materials and products for use in contact with water intended for human consumption with regard to their effect on the quality of the water”. It is a requirement that all the non-metallic materials which come into contact with water destined for domestic use or the production of food products must comply with the specifications of BS 6920. The BS 6920 standard establishes a series of testing methods which assess the suitability of the materials in terms of the following:  Transmission of odours and tastes Provoking changes in appearance (colour or turbidity) Promoting the growth of microbes Releasing substances toxic to human health Releasing toxic metals   TECNOCOAT P-2049 polyurea has recently passed all the tests required for the WRAS BS 6920 standard conducted by the NSF laboratories. The NSF laboratories are internationally renowned for their experience and understanding of USA, European and Asian requirements, and produces reports in compliance with ISO/IEC 17025 signed by certified professional engineers. As a result TECNOCOAT P-2049 has been fully certified as a finish suitable for contact with water destined for human consumption. All the certificates and test results are available for our clients, in various languages, on our website or from our technical department.


What is a VOC?

We produce environmentally responsible products with VOC levels well below permitted limits.  The initials VOC stand for volatile organic compounds, and refer to substances which contain chemical products easily converted into vapours or gases.    Volatile compounds can be natural (methane, isoprenoids emitted by vegetation etc.) or artificial (solvents). There are more than a thousand different compounds which may be considered VOCs, but the most common are the following: methane, ethane, propane, n-butane, n-pentane, benzene, toluene, xylene and ethylene.   In the formulation of paints and coverings it may be necessary to include solvents containing volatile elements. The percentage of these solvents in relation to the solids contained in the formula will determine the product’s VOC. As a result a 100% solid product will have a 0 VOC, without volatile elements, and as a result will be more respectful of the environment and the health of those who come into contact with it; both manufacturers and end users.    Water-based products have a zero or very low VOC.    All Tecnopol products must conform to directive 2004/42/CE of the European Parliament and the Council, dated 21st April 2004, which restricts VOC emissions resulting from the use of solvents in specific paints and varnishes.   In the labeling of all TECNOPOL coatings, primers and varnishes the VOC index of the product is listed together with the corresponding category and the permitted limit. Our company is firmly committed to environmental issues, and as such more than 60% of our coatings and primers contain no solvents (VOC 0) while the remainder have a VOC clearly below the permitted limit (in almost all cases below half).   We will continue to work in this manner – the only way we know how. All products still being developed will have a VOC as low as possible.

DESMOPOL DW. Polyurethane membrane designed and approved for contact with water destined for human consumption

Desmopol DW. The polyurethane approved for contact with water destined for human consumption  The DESMOPOL range of polyurethane membranes continues to grow; just recently we introduced the new DESMOPOL CB, a modified polyurethane elastomer with one component bitumen, now it’s the turn of the new DESMOPOL DW (named after the initials of “drinking water”), specifically designed for use in situations where the membrane will inevitably come into contact with water designed for human consumption. The Tecnopol R+D team has been working hard on the development of this membrane for more than a year, and after numerous tests, they have successfully perfected the formula which now meets all our exacting internal quality standards and with which we are fully satisfied.     The quality tests are designed to determine the suitability of the product in terms of the following mechanical properties: elongation, adherence, viscosity, tensile strength, etc.  After completion of the first phase of testing, we then proceeded to the second stage to determine whether the product complies with the requirements of the purpose for which it is ultimately intended, namely, in this case, contact with drinking water.  After several months of rigorous testing it was confirmed that there was no transfer of membrane particles to the water, after which the product was sent to the NSF laboratories in the UK to undergo the official test procedures for formal approval and certification of use.   DESMOPOL DW has now successfully passed all the tests conducted at the UK based NSF laboratories, and has been duly granted the certificate for use on surfaces designed for contact with water destined for human consumption.   Results were excellent on all the test certificate procedures, which included the following:    Smell and taste of the water (unchanged) Appearance of the water (unchanged) Growth of aquatic microorganisms (no signs detected) Release of potentially harmful or toxic substances (no signs detected) Release of metal traces (no signs detected) DESMOPOL DW passed all the tests conducted by the NSF laboratories and is now officially classified as safe and suitable for use in contact with water destined for human consumption. 


We have expanded our PRIMER range with a variety of new resins.

We will go on to explain their properties and how to select the one best suited for each type of use.   Buying a suit off the peg in a large store is not the same as one made to measure  from a tailor. We could go out dressed in either, but if we expect it to fit perfectly, just like a glove, we would have to opt for the second.   The same is largely true with primers; if we want the job to be finished perfectly and avoid problems in the future we need to select the right product, designed for the type of surface, the prevailing climatic conditions and the system employed. In other words we need to select a primer that has been “tailor made” for our specific needs.  We have developed a range of resins with different properties to maximize adherence to all types of surface, porous or non-porous, and in different temperature and humidity conditions, designed to facilitate the application of all our membranes and flooring systems.     Which primer do I need? PRIMER PU-1000 Resin suitable for repairs and overlaps   PRIMER EP-1040 Maximum adherence on systems used on metal   PRIMER PU-1050 The best option for concrete  PRIMER EPw-1070 All types of surfaces in medium-damp conditions   PRIMER PUc-1050 For concrete in cold environments  PRIMER WET Porous surfaces subject to maximum damp PRIMER EP-1020 Resin ideal for epoxy systems on concrete PRIMER T For use in totally transparent systems   Chief properties of the primer range

Pin-holes, what they are and how to prevent them.

PINHOLES are small craters which form in the applied product during the drying process and which, apart from an aesthetic problem, can also cause functional difficulties, especially in waterproof membranes as they can adversely affect the resistance and efficiency of the coating.       Pin-holes through air or solvent trapped inside the membrane  When membranes are applied which contain solvents it is important to apply thin coats to prevent the appearance of pin-holes. The reason for this is that solvents are very volatile and tend to rise once the membrane has been applied. With a thin coat this is not a problem; the solvents will evaporate more, but if the coat is very thick, apart from a greater concentration of solvents, they will not have time to escape and will remain trapped inside the membrane forming bubbles in the surface. In some cases these bubbles may actually break through the surface, causing the appearance of pin-holes.   In the case of DESMOPOL polyurethane membrane, we can completely eliminate the risk of the appearance of pin-holes or bubbling with the addition of DESMOPLUS. This additive allows the application of DESMOPOL in a single coat with the desired thickness, producing a completely smooth finish with no bubbling or pin-holes. This same problem can occur if the product is foam based or contains air. This is usually due to over energetic stirring of the product. To prevent this we simply need to take the precaution of stirring the product on a slow speed and, if possible, with a basket shaped head.        Pin-holes through trapped air below the membrane  If one applies a polyurea or polyurethane membrane, using spraying equipment, directly onto an untreated or inadequately prepared surface, one is bound to end up with air trapped under the membrane.  This air is less dense than the product which contains it, and while the latter is drying, the trapped air rises to the surface and may cause the feared pin-hole effect.  This same phenomenon occurs when a primer is not applied or the coat is too thin or insufficient.  With the application of hot membranes the drying process is much shorter, which might lead us to believe that the air would not have time to escape, however the membrane temperature in fact also warms the air, making it rise faster, also causing the pin-hole effect.     THE 4 BASIC TIPS FOR PREVENTING PIN-HOLES Always stir the product at low speed and with a “basket” type head  Always correctly prepare the surface to leave it as smooth as possible. Ensure there are no cracks, cavities and other irregularities.  Correctly prime the entire surface, using one or more coats, to ensure that it is as flat and smooth as possible.  When not using the DESMOPLUS additive, which allows application in a single coat, always apply several thin coats.
