DESCRIPTION OF PERFORMANCE

Waterproofing of the floor for the execution of the slabs of flat roofs, building Viura Hotel in Villabuena Alaba (Spain).

Have been waterproofed approximately 1,700 m2 with our P-2049 TECNOCOAT continuous membrane 100% pure polyurea on concrete and stone walls in vertical plane forged concrete also located on the exterior of the complex. In this case, we used merely as decoration, revestiendo the concrete perimeter stone walls surrounding the parking ramp to the environment and perimeters. 

METHOD OF APPLICATION PROCEDURE
The procedure to be followed for this application is as follows:
 
Phase 1: Preparing the substrate
  • Milling of the surface: the surface of milled concrete of the surfaces to be treated to achieve a high adhesion of the system, reducing to zero the air accumulations and therefore the appearance of bubbles or craters on the surface.
  • in the case of low walls of concrete or eliminated no imperfections were prepared as would achieve the effect that the address was more aesthetically architecture of waterproofing protection.
  • General cleaning: we proceeded to the removal of dust from the milling, the work from dirt and other elements from these previous studies that have prevented the optimal adhesion to the substrate.
 
Phase 2: Singular points
Areas such as job boards or expansion, encounters with walls, sinks or other unique elements of the structure or morphology of the work require a focused work to ensure the proper functioning of the system. In this case, work was carried out in the following points:
  • Performing "coving" mortar: In the context of this implementation, it was important to ensure the continuity of the waterproofing system TECNOCOAT P-2049 in all meetings of the vertical perimeters of the covers, and get a good rotation support the membrane vertically. Thus, secured a perfect continuity in the implementation as well as that in the steering turns realizase smoothly and without sharp points, which in the long term due to possible movements of the structure, could damage to the membrane. This work was conducted in concrete encounters with low walls and other existing elements. Importantly, in all these respects, our TECNOCOAT P-2049 does not require any type of concrete or reinforcement.
  • Existing Joint Preparation: Existing joints in the floors and perimeter stone walls were prepared using our elastic putty Putty Desmopol PU., To give flexibility to the area and avoid breakage due to excessive movement of the concrete structure.
 
Phase 3: Implementation of system products TECNOCOAT P-2049
The P-2049 TECNOCOAT system used in this case, was generated by applying the following materials:
  • Primer Primer TECNOCOAT PU manually applied by roller over the entire surface, improves adhesion of existing support and avoids the presence of entrapped air.
  • TECNOCOAT P-2049 membrane: membrane 100% pure polyurea TECNOCOAT; continuous and fully bonded to the support, is applied by spray equipment GRACO-EXP2 with mixture control, temperature and pressure of the liquid components. The application was made directly over the primer in several continuous layers until the required thickness by our ETA document 11/0357.
The finish of the ceramic on the terraces was waterproofing and insulation layers, ie in this case not used for protection aliphatic coating.
The low walls of concrete of the entrance area were completed with the application of P-2049 TECNOCOAT directly on the concrete, leaving voids and imperfections typical view of the execution of concrete, as prescribed by the architecture of the project management, or uncoated additional coatings.
 
 
Advantages of applying
Factors favorable to the implementation of the system TECNOCOAT P-2049, and decided to put into play against other waterproofing systems, were:
  • optimum sealing, safety and waterproofing roofs and terraces.
  • ideonidad TECNOCOAT aesthetic finish P-2049, referring to the architectural style and aesthetic of the resort, applied in the low walls of reinforced concrete.
  • Full continuity of the waterproofing in all aspects of the morphology of execution.
  • high resistance to abrasion and puncturing, ensuring tightness.
