Filterwrap non-woven geotextile helps to provide effective drainage for a range of residential and landscaping applications. Filterwrap separates and filters particles of dirt, sand and aggregates to improve drainage in subsoils and behind retaining walls.
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

WHY CHOOSE FILTERWRAP?
- Allows rapid drainage
- Damage-resistant
- Lightweight and easy to handle rolls, convenient for the trade
- Reduces aggregate wastage
- Flexible for irregular shapes of land formations
- Acts as a barrier to reduce weed growth
APPLICATIONS
FUNCTION
Drainage
Geosynthetics can act as a drain to carry fluid through less permeable soils. Ideal for use in subsoil drainage systems, can be used to dissipate pore water pressures at the base of road and railway embankments, sports fields and behind retaining walls. Facilitates surface water runoff.
Filtration
Geosynthetics can act as a filter by allowing water to move freely through while preventing the migration of fine particles. Often used to prevent soils from migrating into drainage aggregate or pipes while maintaining flow. Can also prevent soil erosion in coastal and riverbanks when used below loose stones or rocks and other material.
Separation
Geosynthetics can be used to prevent the intermixing of soil types of different sizes in the construction of roads, railways, and embankments where the ground is soft and unstable to maintain the integrity of each material while allowing free passage of liquids or gases. Using a layer of geotextile to separate the soft ground from the fill material reduces the amount of fill required, increases the lifespan of the road or rail structure and cuts long-term maintenance costs.
