Integrally the SILTBLOK unit has a unique filter barrier, which is made up of three micro porous plastic sections, which are manufactured from 100% waste plastics. This unique and innovative filter design will drain water very quickly but the structure retains water which helps repel silt. So the screen will not clog or blind, offering an exceptional yet simple sustainable solution. The filter has a permeable area of 50%, so provides exceptional flow, whilst blocking up to 95% of even the finest of silt.

The Silt Sentinel Range has been designed for the catchment and removal of silt and debris from the run off from impermeable and hard standing surface areas, such as: roofs, path and driveways, patios, car parks, roads and highways. Installation of a Silt Sentinel as part of a SuDS design, will provide effective primary treatment for the surface water run off, improving water quality downstream and in turn, helping prevent flooding.
