Geotextile Fabrics are used to provide effective separation and protection between soil and hardcore layers whilst allowing the flow of moisture.
The geotextile fabrics can act as a strong barrier to particles whilst still allowing free drainage.
This prevents soil from slumping in constructions such as artificial islands, embankments and cuttings.
Geotextile fabrics also prevent the ingress of particles into drains and outlet pipes.
Often underground permeable pipes will be wrapped in geotextile to prevent them becoming clogged up over time.
