Geotextile protection for linings
- basements
- bridge abutments and decks
- canals
- roof gardens
- service reservoirs
- tunnels
- retaining walls
Coatings and membranes applied to concrete structures are often in need of protection. Angular materials in contact with the proofing, whether by design or by accident, are capable of penetrating the barrier, particularly if the structure is to be subjected to high confining pressures.
Thick, non-woven geotextiles are the easily-applied and proven solution.
- Protection during installation and in service life
- Optimum puncture resistance at minimum cost
- Narrow widths available for ease of handling (typically 2m wide)
- In-plane drainage options
Whether it’s a polymeric or a bituminous membrane, applied vertically or horizontally, above ground or below, protection to prevent puncture will be required on one or both sides. One of the GEOfabrics’ range of thick, geotextiles will provide the necessary level of protection.

Combining membrane protection with drainage
The Protexia products combine the inherent protection capability of the geotextiles with the additional benefit of in-plane drainage. If the objective is to install a protection layer and prevent the build up of pore water or gas then installing one product, instead of two, will save time and money.
The drainage capacity is achieved by incorporating band drains within the geotextile, or by creating a composite with nets or cuspates (eggbox-like sheets) as the drainage component. So, depending on the anticipated pore water/gas levels and the confining load, the most suitable solution can be chosen.
