What is Filter Fabric?
Definition of Filter Fabric in Construction
A material that is designed to allow water to flow thru but retain sand, sedimentation materials , soils, etc. that are in the water.
This fabric is used to reduce material flowing into a stream or body of water, or to retain the fines and material from leaching out of a system. Filter fabrics are used extensively in the stabilization of project sites that have less than perfect soil conditions. In addition to filtering out fines, fabrics are also used to encompass controlled stone and bagged stone, to create drainage behind walls, or other impervious structures, that may hold back an accumulation of water. Filter fabric is used to keep a footing drain free of silt and debris as well as ensure a drywell remains sediment free. Filter fabrics are extremely common in the construction industry and are improving in performance as technology advances.
