Silt Sentinel SILTBLOK SSSB1200

Designed for installation upstream of large volume, cellular/crate – attenuation systems, ponds, swales and irrigation systems


1200mm diameter, single piece – factory built units, delivered to site ready to install. SILTBLOK units feature a robust, impact resistant, twinwall body, with a choice of main channel pipework diameters from 100mm up to 600mm, with extra inlets available on request.

Integrally the SILTBLOK unit has a unique filter barrier, which is made up of four 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.

Chambers can be supplied with fitted ladder if required
