Storage water tanks
With time and use water tanks may develop leaks, especially as they are not normally constructed from a single piece. TECNOCOAT flexible systems allow interior waterproofing regardless of the type of material from which they are constructed or the liquid stored inside. (Check compatability in each case).
We have a certificate for contact with foodstuff and drinking water, the European certificate for protection of structural concrete (EN-1504) and the ETA certificate for 25 years of working life.
Construction or renovation of storage tanks
The application of TECNOCOAT membrane provides perfect waterproofing and protection for storage tanks, both metal and stone, designed for practically all purposes (irrigation or drinking water, alcohol, chemical products, food storage etc.).
1. Tank support
The surface should be initially prepared.
A transversely deformable adhesive band, formed of a viscous-elastic layer coated on a nonwoven mesh. The nonwoven element allows adaptation to the support of the band and is highly recommended for specific applications of DESMOPOL liquid polyurethane and polyurea membrane.más información
MASTIC PU is a single component polyurethane mastic that cures rapidly on contact with atmospheric moisture, forming a hard sealant, elastic and of a medium-high elasticity modulus. For sealing of vertical and horizontal joints.más información
A primer resin will first be applied to ensure adhesion.
PRIMER PU-1000 is a single component, low viscosity, high solids content polyurethane resin. It has been specifically designed to increase bonding and improve the surface leveling of the substrates prior to the application of the DESMOPOL or TECNOCOAT.más información
PRIMER PU-1050 is a two-component, low viscosity 100% solid resin. It has been specifically designed to increase bonding and improve the surface leveling prior to the pure polyurea TECNOCOAT or DESMOPOL systems. It can be applied on porous substrates such as concrete or mortarmás información
PRIMER PUc-1050, is a two-component, low viscosity, 100% solids polyurethane resin. It is specially designed to increase the adhesion of waterproofing systems, improve the rough floor in structural surfaces such as concrete or mortar, in waterproofing systems applications as TECNOCOAT pure polyurea or polyurethane DESMOPOL, and always in low ambient temperature conditions.
3. Waterproofing membrane
The TECNOCOAT membrane will then be applied directly over the primer. No additional finish coat will be required as TECNOCOAT holds a certificate for safe contact with both drinking water and alcohol.
The 100% pure polyurea TECNOCOAT P-2049 has been developed as a sprayable and aromatic coating, suitable for waterproofing, protection, and sealing. It is made up of two high reactive liquid components, isocyanates and amines, which once mixed form an aromatic, continuous, seamless, high density, solid and elastic pure polyurea membrane. It has CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the UE 305/2011 regulation.más información
The 100% pure polyurea TECNOCOAT P-2049 LV membrane was developed as a coating suitable for waterproofing, protection and sealing in general. The pure polyurea TECNOCOAT P-2049 LV membrane is made up of two high reactive liquid components, isocyanates and amines, which are mixed together using spray equipment (TC2049 http://spray-equipment.tecnopolgroup.com/), to form an aromatic, continuous, without joints, high density, solid and elastic pure polyurea, for protecting the polyurethane foam TECNOFOAM (SPF)
The 100% pure and elastic polyurea TECNOCOAT P-2049 EL system was developed as a single coating suitable for waterproofing, protection, and sealing, especially in elements with structural movements. The pure polyurea TECNOCOAT P-2049 EL membrane is made up of two high reactive liquid components, isocyanates, and amines, which are mixed together using spray equipment. TECNOCOAT P-204 EL is an aromatic high density and elastic pure polyurea and excellent elasticity.más información
