Waterproofing membrane
Water-Stop

The WATER-STOP waterproofing sheet is a waterproof, elastic geotextile sheet with a very good grip on surfaces and with a very small thickness due to its innovative multilayer extrusion manufacturing process.

This sheet responds to an innovative concept in the way of waterproofing, since it can be installed under the coating on floors and walls thanks to its fibrous faces integrated in the waterproof membrane.

This waterproofing membrane has been chosen by a large number of architects and installers, since its flexibility, manageability and durability make it one of the best options for any type of waterproofing.

A waterproofing film for all uses

Water-Stop is a technical waterproofing membrane developed to solve waterproofing in multiple applications with a single product: showers, bathrooms, terraces, decks, swimming pools and areas exposed to humidity. Its 4-layer structure, unique in the market, improves the stability, resistance and safety of the system, helping to protect the critical points of the installation and reducing the risk of leaks. A practical solution for professionals looking for speed of installation, reliability on site and durable waterproofing before the final coating.

Water-Stop waterproofing sheet uses

● USES

Waterproofing membrane for terraces and roofs.

Water-Stop is a waterproofing membrane ideal for terraces or any type of outdoor roofing. Among its great functions for outdoors we can highlight: terraces, walkable and non-walkable roofs, rooftops, balconies, roof gardens, patios, fountains ….. In addition, we must emphasize that if the support is in good condition we can waterproof a terrace without removing the old floor, saving a lot of time and cost of installation and becoming one of the best solutions for renovations or rehabilitations.

Waterproofing film for showers, bathrooms and interiors

The WATER-STOP shower waterproofing membrane is perfect for waterproofing built-in showers, bathtubs, bathrooms (walls and floors) etc. Thanks to its flexibility, lightness and its high mechanical grip to type C2 cementitious adhesive, it is one of the best solutions that we can find on the market to waterproof your bathroom.

Thanks to this waterproofing sheet for shower, all critical points are completely waterproofed (with the help of the accessories shown below).

Waterproofing film for swimming pools

Our waterproofing sheets for swimming pools are formed by a multilayer structure that, apart from the waterproofing itself, allows bridging small cracks, absorbing the tensions of the union between coatings and support and reducing pathologies such as peeling and carbonation. All this helps to ensure the integrity of the pools avoiding possible humidities or filtrations.

One of the main advantages of the WATER-STOP waterproofing membrane with respect to other waterproofing membranes on the market is its durability (since if it is installed following our instructions and protected from the sun, its durability is for life) and the ease of installation, not requiring heavy machinery and being able to be installed with a single operator. Another great advantage is its ability to waterproof the pool over the old gresite.

● FAQS

What is the Water-Stop waterproofing membrane?
Water-Stop is a flexible waterproofing membrane that is bonded with tile adhesive directly onto the surface, creating a continuous barrier against water. It is designed to protect wet areas such as showers, bathrooms, terraces, balconies or swimming pools.
What advantages does the Water-Stop waterproofing membrane offer compared to other systems?
Unlike liquid or bituminous systems, the Water-Stop waterproofing membrane offers clean, fast application and an unlimited service life. It also guarantees a uniform thickness and total waterproofing without the risk of cracks or shrinkage.
Where can waterproofing membranes be installed?
Waterproofing membranes can be applied both indoors and outdoors. They are ideal for showers, bathrooms, kitchens, terraces, balconies and areas at risk of leaks. They can also be used on walkable roofs, swimming pools and high-use wet areas.
How is the Water-Stop waterproofing membrane installed?
Installation is carried out with C2-type flexible tile adhesive and a notched trowel. Joints between membranes are sealed with W-S BAND or by overlapping, and junctions with drains or walls are reinforced with specific accessories. Once installed, it can be covered directly with ceramic tiles or natural stone.
Can the waterproofing membrane be used under underfloor heating?
Yes. The Water-Stop membrane is compatible with underfloor heating systems, as it withstands thermal variations and maintains its elasticity without deteriorating.
How long does the waterproofing membrane protection last?
If installed correctly, the Water-Stop waterproofing membrane provides long-lasting protection throughout the service life of the covering, preventing leaks and structural damage caused by moisture.
What adhesive should be used with the Water-Stop waterproofing membrane?
It is recommended to use a C2-type flexible tile adhesive and a waterproofing cement for overlaps and joints, such as EASEAL, to ensure maximum adhesion and watertightness of the waterproofing system.

Technical information of the Water-Stop waterproofing sheet

● TECHNICAL

Water-Stop acts as a waterproofing film protected under coating, designed to form a continuous water barrier on floors and walls. It is suitable for flat roofs, terraces, balconies, swimming pools, planters, fountains, exterior surfaces and interior wet areas. On site, it works within a bonded system and is covered by the final coating, providing water tightness, resistance to root penetration, crack bridging capacity of up to 3 mm and performance as a vapor barrier in accordance with the requirements of CTE DB HS 1. It can also be used at temperatures between -20 ºC and +80 ºC, which allows its application in indoor and outdoor environments with different thermal and humidity requirements.

Water-Stop is manufactured with a multi-layer structure consisting of non-woven / double film / non-woven. The inner film is 100% copolymer EVA and the outer nonwoven is composed of 50% polyester and 50% polypropylene. The film has a mass of 260 g/m² and a nominal thickness of 0.5 mm. For fixing on traditional substrates, cement adhesive type C2 is used; for substrates such as plaster, existing ceramic or other materials, the compatibility of the adhesive with the substrate must be verified. For laying ceramic tiles or similar coverings on the sheet, cement glue type C2 is also used, while for wood finishes, textiles or other coverings, a specific adhesive compatible with the material and suitable for humidity must be used. C2 tile adhesive cement can be used for overlapping joints in showers and small interior surfaces that cannot be flooded; when maximum watertightness is required, the joints should be made with EASEAL polymer cement or with W-S MASTIC type adhesive sealant.
