Henrico County Slipline

HALL cleaned, televised and sliplined 1800′ of existing 72″ PCCP sanitary sewer with 66″ ID Flush Wall HOBAS Fiberglass Pipe, then grouted the annular space with lightweight grout, and set two new manholes, and televised the completed installation. Flow was running continuously and at a very high velocity, but no bypassing was required, as is typical for this preferred method of large diameter sewer rehabilitation.
