Because non-woven geotextiles such as Filterwrap are highly porous, water can pass freely while fine particles are prevented from moving through. This allows Filterwrap to be used where drainage or control of groundwater is an issue.
Often used in a variety of applications:
- Ground water drainage behind retaining walls
- Separation over soft ground in driveway construction and gravel paths
- Separation between soil and drainage aggregates in planter boxes and roof gardens
- Lining of subsoil drain trenches
