Permavoid Diffuser

Diffuser units are a recognised method for efficient diffusion of collected rainwater run-off into and out of the voided sub-base aggregate layers beneath permeable pavements. Diffuser Units are fully compliant with BS7533-13:2009 and arrive to site ready to install with no-site assembly required.

Silt Catchpit

Purpose-built high density polyethylene (HDPE) pre-fabricated catchpit chambers are ideal for stormwater drainage systems. WASP Catchpit chambers are designed to separate silt and other particles, helping to improve the quality of water before it is reintroduced into the environment. They can be integrated into any drainage system requiring ‘in line’ silt and debris separation prior to attenuation or infiltration.
