Bluestone Holiday resorts foul system which comprised of 150mm Clay Pipes upto 9m deep had infiltration within the pipe work system and also within the MHs. Due to this the SPS downstream was overloading and non-compliant.
Drainforce were approached to provide a solution on a selection of 400m of the system to reduce the infiltration through a mix of UV Lining and MH Sealing.
Drainforce recommended lining though MHs where possible where infiltration was gushing and to divert connections to other Manholes.
This Process allowed Drainforce to line though Specific manholes with a high level of infiltration ensuring they sealed fully.
Once the liner was cured the sealed manholes were covered with concrete and type one.
A specified number of Manholes were sealed by lowering in 1000mm diameter rings into into 1200mm rings and backfilling the annulus with concrete to ensure the Manholes was fully sealed and secure.
