Katam Drainage use Quicklock, German engineered no-dig, trenchless repair system for rehabilitating existing sewer & stormwater pipelines. The seal consists of a heavy grade (V4A, 1.4404, SS 316L) expandable stainless steel band and EPDM rubber gasket. Each sleeve has ratchet mechanisms that allows it to be rolled tight to fit inside the pipe and then expanded pneumatically to facilitate a permanent pressure contact of the seal onto the host pipe. The ratchet mechanism ensures the sleeve is locked permanently into place. Quicklock installs quickly and is a flexible, structurally sound repair system with minimal prep, minimal labour and minimal risk. The use of Quicklock, means that costly excavation is a thing of the past.
