Hotel RIU PANAMA - Hotel Riu Panam

Main system employed:
Cubiertas planas
Year of execution:
12000 m2

E X E C U T I O N    D E S C R I P T I O N  

It consists of Waterproofing of flat concrete slabs in the new implementation of the Riu Panama  Hotel in Ciudad de Panama, for the formation of flat roofs and terraces. 
A surface of 12.000m2 have been proofed with our Tecnocoat P-2049 continuous membrane 100% pure polyurea on reinforced concrete flat slabs in  both upper terraces as roof of reception hall of  hotel. 
The application area consists of large areas complemented by walls of reinforced concrete topped metal sections forming the various parks. The final design was completed in soil and vegetation, following a horticulture project, with circular skylights made of reinforced concrete, structural expansion joints, and also with drains for water collection.

The procedure followed in this application is as follows: 
 First step:  support preparation
  • Milling of the surface:  surfacing of the concrete slab, to obtain a high  adhesion of the system and reducing at zero the accumulation of air and therefore the appearance of bubbles or craters in the surface once the membrane is applied. 
  • General Cleaning: removing with vacuum of dust, dirt and other material generated during earlier work and that may prevent optimal adhesion to the substrate. 
Second step: singular points 
They are the elements as dilatation joints, encounters with walls, drains or other specific and singular points of the structure and surfaces. They require focused work to ensure proper system operation. In this case, the work was done in the following points: 
  • Realization of half-cylinder mortar: in this application, it was important to ensure continuity of the waterproofing system  Tecnocoat P-2049 in all encounters of the zones with vertical walls, and get good support for vertical membrane. Thus, a perfect continuity is ensured on the sharp points, which in the long term because of possible movements of the structure, which can damage the membrane. 
  • This work was done on the intersections with the walls, skylights and other existing elements. In this way the membrane Tecnocoat P-2049 requires no assembly or reinforcement extra systems. 
  • Preparation of existing joints: joints on existing slabs and perimeter walls were prepared using our Desmopol PU elastic sealant (mastic), to achieve a perfect flexibility and prevent breakage due during possible excessive movement of the concrete structure.. 
Third step: Tecnocoat P-2049 application
The Tecnocoat P-2049 system used on this project is constituted by: 
  • Primer Tecnocoat Primer PU: applied with a roller over the entire surface, improves the adhesion of the existing support and avoid the presence of trapped air. 
  • Membrane  Tecnocoat P-2049: Tecnocoat polyurea membrane 100% pure, continuous and fully bonded to the support, is applied by spraying equipment as graco E-XP2, by an instantly control of mixture, temperature and pressure of the liquid components. It is applied directly on the primer, in many continuous layers until the thickness required by our document ETA 11/0357. 
  • Varnish Desmopol ADY 2C: is a polyurethane protective varnish to protect the superficial color of polyurea  Tecnocoat P-2049.  it was applied with airless sprayer machine, in  order to increase the execution performance. This coating also has high resistance to the passage or traffic which gives the possibility to be achieved with various modes for various uses, without devaluing the properties of waterproofing system.

The factors that determined the use and employment of Tecnocoat P-2049 system, and not other sealing systems, are: 
  • Excellent sealing at intersections with walls of reinforced concrete. 
  • Complete protection for metal profiles at the top between the walls. 
  • Total continnuity of the waterproofing membrane in all aspects of the area to be waterproofed, taking into consideration the details of construction. 
  • High resistance to abrasion and punching,. 
  • Secure and safety - the tightness of the green roof, with a high protection due to compliance with the load capacity to support specified in the ETA. 
  • Similarly, their qualification for use on roofs with S1-S4 classification of slope (inclination), as evidenced by ETA 11/0357.
