Case Studies

DESCRIPTION OF PERFORMANCE

Waterproofing and landscaping covered underground parking in residential housing in the town Azken Portu Zizurkil Gipuzkoa.

They have approximately 2,800 m2 waterproofed with our P-2049 TECNOCOAT continuous membrane 100% pure polyurea on concrete slabs, placing on top VYDRO greening system of polyurethane foam, with sedum plants as finishing system green roof.

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 slabs, to obtain high adhesion of the system, reducing to zero the air accumulations and therefore the appearance of bubbles or craters on the surface.
• General cleaning: removing any dust or dirt from the previous operation, the entire surface to improve adhesion of the membrane of pure polyurea TECNOCOAT P-2049.

Phase 2: Implementation of system products TECNOCOAT P-2049

The P-2049 TECNOCOAT system used in this case, was generated by applying the following materials:

TECNOCOAT Primer Primer PU: polyurethane based two-component primer, manually applied by roller over the entire surface, improves adhesion of the existing bracket and prevents the presence of entrapped air.

TECNOCOAT P-2049: pure polyurea membrane 100% 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.

Step 3: Spread the substrate landscaped VYDRO

Finally, in the top of the pure polyurea membrane TECNOCOAT P-2049, is extiendió substrate VYDRO polyurethane foam of high water retention, adding the finishing layer vegetable garden.

Advantages of applying

The favorable conditions and points that decided the implementation of our continuous membrane combined TECNOCOAT pure polyurea waterproofing P-2049, the system VYDRO green roof substrate were:

• Optimum waterproofing encounters both low walls perimeter contour, as in the rest of the surface to be treated.
• Run very fast compared to other systems, which due to the amount and frequency of rainfall in the area, make the system perfect TECNOCOAT P-2049 to avoid delays in execution of work.
• Full continuity of the waterproofing in all aspects of the morphology of the execution, taking into account the existing construction details such as matches with existing vertical walls.
• high resistance to puncture and abrasion, which ensures its tightness in cases like the present one: a large area that can be used as material stockpile areas during execution.
• in the same way, for the application classification for roofs with classification S1-S4, that is, covered with zero slope as is reflected in the ETA 11/0357, making it suitable for use.
• green roof system with a landscaping VYDRO perfect, fast execution, and easy maintenance. The high water retention capacity of the polyurethane foam system VYDRO achieves a saving in the consumption of irrigation water from the entire deck.
