Manufactured by Taltex
Geotextile
Needle-punched non-woven geotextile is our core production. Permeable and rot-proof, it separates layers, filters water, drains and protects waterproofing membranes. Eleven standard grades from 100 to 1200 g/m², in widths up to 6 metres.
Key features
Controlled permeability
The O90 opening size is measured for every grade, so the product can be selected against the actual grading of the soil.
Mechanical bond
Needle punching entangles the fibres with no chemical binder. The material stays supple, lays flat and follows irregularities in the formation.
Resistant to soil agents
Chemically inert and rot-proof, it withstands the agents found in natural soils and repeated wetting and drying cycles.
Typical uses
- Separation beneath a sub-base
- Filter in a drainage trench
- Underlay for erosion control
- Geomembrane protection
- Embankment reinforcement
APPLICATIONS
On site
Protection geotextile laid on a slope, ahead of the geomembrane
