Permeable concrete mattress with filterpoints
For stable bases and low hydraulic loads
Incomat Filterpoint offers the ideal erosion control solution for applications subject to low hydraulic loads requiring a water-permeable concrete mattress. The mattress comprises a two-layer woven fabric, with the two woven layers are joined together by a regular arrangement of woven-in filterpoints. The in-situ concreting process ensures that the mattress adapts to the base profile, thereby lowering the risk of void formation below the revetment.
Incomat Filterpoint is normally specified as an alternative to rip-rap, pitched stone or conventional concrete slab revetments on account of its lower cost and superior performance. Incomat Filterpoint acts in conjunction with the concrete to create a highly efficient, permeable revetment suitable for strong bases and low hydraulic loads.
