The HEADWALLBLOK provides a sustainable and maintainable solution to prevent Total Suspended Solids(TSS) from migrating into the outfall of the surface water system during the construction phase, helping prevent and alleviate pollution to the downstream connected wetland, pond or watercourse
Utilising a 100% recycled thermoplastic block (blok). This blok is installed against the headwall forcing all water flow through the blok before reaching the downstream connected wetland, pond or watercourse, filtering out TSS including silt up to 30μm (0.03mm)
This model accommodates pipework up to 450mm internal diameter
The blok slider assembly is designed to be removed and simply slides into the systems galvanised guide rails, which are installed to the respective headwall using M12 fixings (not provided). The blok assembly is then inserted into the mounted guide rails
