What is geotextile sheeting?
The geotextile waterproofing sheet is a textile with a laminar and flexible structure, manufactured from synthetic fibers such as polypropylene or polyester.
Types of geotextile sheeting
Depending on its manufacturing method (woven, needlepunched or heat-set nonwoven, or a combination of both), it obtains outstanding mechanical and hydraulic properties, such as high tensile strength, drainage capacity or the possibility of acting as a filter.

Application examples |
|
Fabric |
– High tensile strength – Low deformability |
Manufactured with propylene, polyester or high density polyethylene fibers. |
– Road and highway reinforcement (base and sub-base) – Earth retaining walls – Slope stabilization – Embankments on soft soils |
|
Nonwoven |
– Good filtration and drainage – Flexibility – Adapts to irregular surfaces -Impact absorption |
Propylene or polyester (short fibers or continuous filament, joined by mechanical or thermal punching. |
– Subway drainage systems (surrounding pipelines or drains) – Protection of waterproofing sheets on roofs and terraces – Filtration in dams or canals – Separation in gardens and landscaping |
|
Mixed / Composite |
– Combine reinforcement and filtration/drainage – Multipurpose solution |
Propylene and/or polyester blend integrating woven and nonwoven layers |
– Landfills (reinforcement + drainage/leachate) – Green walls or landscaped areas (structural reinforcement + fluid control) – Road works in difficult terrain (reinforcement, separation and drainage at the same time) |
There are variants of geotextile sheeting for specific purposes, such as the nonwoven polyester geotextiles used in building construction for waterproofing.

What is the difference between a geotextile sheet and a geomembrane?
A geomembrane is a synthetic sheet made of plastic polymers that does not allow water or gases to pass through (it can be HDPE, PVC, EPDM or EVAC). It is used to waterproof surfaces that are in permanent and continuous contact with water, contaminating liquids, humidity or steam, but it does not drain or filter. It is used in ponds and artificial ponds, landfills, waste tanks, building roofs, tunnels, cisterns…
The difference between a geotextile sheet and a geomembrane is its composition, since the former uses synthetic fibers, while the latter uses polymers. This makes their texture different, while the former is more porous, the latter is totally impermeable.
Hybrid geotextile waterproofing sheet that combines the performance of geotextile sheets and geomembranes.
There are other types of mixed or hybrid geotextile sheets developed specifically for waterproofing buildings.
These waterproofing geotextile sheets are formed by several technical layers. In the center, they incorporate a waterproof membrane with two layers of EVAC plastic film, so we are talking about a waterproof geomembrane. In addition, on their outer sides, they have non-woven geotextile layers to improve the adhesion of the type C2 tile adhesive cement.
GURU develops, manufactures and markets these hybrid sheets that easily adhere to surfaces using cement glue or cementitious adhesives and can be quickly cut, glued and manipulated. This makes these hybrid sheets the ideal solution for waterproofing building areas and fast and efficient renovations.
For installation, the Water Stop waterproofing membrane is placed under ceramic tiles with tile adhesive.
Water stop has a minimum thickness of 1 mm which makes it ideal for:
- Waterproofing new construction projects
- Renovation of terraces and balconies that have suffered problems due to the aging of previous waterproofing applied.
- Solving leakage problems
- To achieve an effective application due to its flexibility and adaptability to projects of different sizes.
- Waterproofing under ceramic tile
- Control expansion and contraction movements
- Quick installations by making it easy to handle due to its light weight
- Care for and protect the environment as it is a recyclable and ecological product (it contains the DAP seal and its manufacture does not pollute).
It is a high quality product designed by the brand to offer a waterproofing solution for interiors and exteriors with excellent adhesion to the surface by means of cementitious adhesives.
Among the advantages of this waterproofing membrane are its elasticity, which facilitates its adaptation to the base and avoids cracks, and its resistance to temperature changes to guarantee its durability.
This waterproofing membrane can be used for site showers and adapted bathrooms, terraces and walkable or non-walkable decks, swimming pools, ponds and basements.

Preguntas frecuentes sobre lámina geotextil y Water-Stop de GURU
¿Una lámina geotextil es siempre impermeable?
No. Las láminas geotextiles estándar, tanto tejidas como no tejidas, no son impermeables. Su función principal es protección, separación o drenaje. Las láminas impermeables multicapa como Water-Stop de GURU sí bloquean completamente el paso del agua.
¿Qué diferencia hay entre una lámina geotextil y una lámina impermeabilizante?
La lámina geotextil no impide el paso del agua, mientras que una lámina impermeabilizante actúa como barrera estanca. Water-Stop combina capas técnicas que protegen y, al mismo tiempo, garantizan impermeabilización total.
¿La lámina Water-Stop se considera una lámina geotextil?
Water-Stop no es una lámina geotextil convencional. Es una lámina impermeabilizante multicapa que integra velos técnicos tipo geotextil para mejorar la adherencia y la protección, junto con un núcleo totalmente impermeable.
¿Es necesario aplicar capas impermeabilizantes adicionales sobre Water-Stop?
No. El núcleo central de Water-Stop ya es impermeable. Solo es necesario sellar correctamente las juntas y encuentros con productos compatibles como WS-Band para asegurar la continuidad del sistema.
¿Se necesita imprimación o maquinaria especial para colocar Water-Stop?
No. A diferencia de otros sistemas, Water-Stop no requiere imprimación, soldadura ni maquinaria especial. Se coloca con adhesivo cementoso tipo C2, de forma similar a la colocación de una baldosa.
¿Puede sustituir Water-Stop a una lámina geotextil tradicional?
En sistemas donde además de protección se necesita impermeabilización, sí. Water-Stop aporta funciones superiores a una lámina geotextil convencional, ya que protege y bloquea completamente el paso del agua.
¿En qué aplicaciones se suele usar una lámina geotextil?
Las láminas geotextiles se utilizan como capa de separación, refuerzo o protección en cubiertas, drenajes, jardinería, pavimentos y sistemas de impermeabilización. No sustituyen a una lámina impermeable cuando existe riesgo de filtraciones.
¿Es Water-Stop adecuada para reformas sin experiencia avanzada en impermeabilización?
Sí. Las soluciones de GURU están pensadas para facilitar el trabajo a profesionales de la colocación en general. Water-Stop se corta fácilmente, no necesita tiempos de secado, se puede revestir de inmediato y es ligera y manejable.
¿Qué ventajas ofrece Water-Stop frente a una lámina geotextil tradicional?
Ofrece impermeabilización total, mayor durabilidad, mejor comportamiento en juntas y esquinas, y elimina la necesidad de aplicar productos impermeables adicionales sobre la superficie.
¿Se puede colocar cerámica directamente sobre Water-Stop?
Sí. Water-Stop permite el revestimiento inmediato con cerámica u otros acabados sin tiempos de espera, lo que acelera la obra y reduce riesgos de fallo.
