Woven geotextiles
A woven geotextile (also called root fabric) is a (water) permeable textile manufactured from polypropylene granules. This geotextile has several applications:
- Stabilizing and/or strengthening the subsoil to increase its load-bearing capacity
- As filter and drainage material to allow liquids to pass through and prevent passage of soil particles
- As a separation material to prevent mixing of different soil layers
The incorporation of these geotextiles in the work, for example, prevents sand and/or granules of good quality from mixing with the underlying soil.
Woven geotextiles play an important role in the construction of (temporary) roads, foundation reinforcement in asphalt paving/paving stone pavement, foundation layer in unpaved road structures, parking lots or coastal defense works such as embankment protection and reinforcement of dikes and banks.
TF woven geotextiles with tensile strengths above 80 kN/m, the so-called heavier fabrics, are used in conditions where high loads are required, such as in temporary soil reinforcement, bank reinforcement and soil stabilization.
Types and tensile strengths
Woven geotextiles are available with a range of opening sizes and difference tensile strengths directly from stock. Within the range we have various tensile strengths in stock including:
- TF18/18 kN/m | +/- 100gr/m2
- TF25/25 kN/m | +/- 125gr/m2
- TF35/35 kN/m | +/- 160gr/m2
- TF40/40 kN/m | +/- 190gr/m2
- TF60/60 kN/m | +/- 280gr/m2
- TF80/80 kN/m | +/- 370gr/m2
The TF18/18 is stocked as standard in the following sizes: 100 running meters with widths of: 50 cm, 65 cm, 80 cm, 105 cm, 131 cm, 160 cm, 200 cm, 262 cm, 325 cm, 425 cm, 525 cm.
Features and benefits
- Lifespan of at least 100 years
- Mechanical properties offer maximum strength at minimum cost
- Greater mechanical strength per unit weight compared to similar nonwovens, which makes it extremely suitable for separation
- Greater mechanical strength per unit weight compared to similar nonwovens, which makes it extremely suitable for separation
- Significant cost savings compared to traditional methods
- Resistance to acids and alkalis at ambient temperatures
- High biological resistance
- Separation, filtration and stabilization in one product due to fine structure
- Due to the high tensile strength, the thickness of the foundation package can be reduced
