It consists of waterproofing of flat and semi-inclined reinforced concrete slabs, during the new execution 

of AVE railway station for transit of high Speed train. 

It was waterproofed approximately 10.000 m2 by Tecnocoat P-2049 system, continues membrane of 100% 

pure polyurea on reinforced concrete covering all building space. 

Waterproofing of slabs covering the station.

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 (oil,grease,paint…ect) 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.

A D V A N T A G E S 

The factors favoring the application of the waterproofing and coating system Tecnocoat P-2049, and not 

to use other systems were as follows: 

. – waterproofing of encounters with perimeter walls, as in the galvanized planters, large covering and 

coating of all surfaces and fixtures. 

. - fast execution compared with other systems, which due to the frequency of rainfall in the area, make 

the P-2049 Tecnocoat system ideal for preventing slippage of work. 

. - Complete continuity of waterproofing membrane on all surfaces and forms without joints or overlaps 

use. 

. - 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
