propiedades lámina impermeable water-stop


The waterproofing membrane WATER-STOP is a waterproof elastic geotextile membrane with a very low thickness due to its exclusive multilayer extrusion process and with a very good grip on surfaces by the good combination achieved with the C2 cement glue. 

This is an innovative concept in waterproofing membrane as it can be installed under the floor covering and on walls because of its fibrous faces integrated into the waterproof membrane.

“It is also the most advantageous waterproofing solution when it comes to waterproofing renovation, since with WATER-STOP waterproof membranes it is possible to install them on top of existing floor and then lay the new tiles without exceeding the height of the access to the dwellings”

Uses of waterproofing sheets WATER-STOP

The use of WATER-STOP membrane is very broad because of its composition of a central waterproof membrane made of two layers of plastic film (EVAC) and non-woven fleece of polypropylene fibres on each side.  

This waterproofing membrane can be used indoor and outdoor, for site showers, adapted bathrooms, flat walkable roofs, swimming pools, basement, etc.

Bridges cracks and allows small movements.

The elasticity of the inner waterproof membrane and its combination with the fibers, allows each element to have small movements separately, such as those of expansion – contraction.


Waterproofing membrane accessories WATER-STOP

WATER-STOP flexible waterproofing membrane accessories facilitate problem solving of the critical points of the entire installation, like corners and nooks, floor-to-wall junctions and connections to building elements. It is applied by gluing with cement glue type C2 and a notched trowel. Without fire or toxic or dangerous solvents. Waterproofing with WATER-STOP greatly reduces costs, reduces material consumption and increases efficiency and labour time.
