Catch-pit Ancillaries


Rubber Stone Guards

Patent No. - 2542850 

Factory fitted to suit TDK and TDE pipes, Rubber Stone Guards reduce the ability for the granular fill material to ingress the GRP preformed sump unit during installation. This reduces the time taken on site to install a catch-pit as no additional works are required to ‘dig out’ any fill material that has accumulated in the catch-pit sump.
