GU LINER SYSTEMS

IMPORTANT DESIGN FEATURE:  
The compression seal gasket is mounted in an intgrally cast-in-place GU PIPE BELL Assembly which is monolithically bonded to the interior manhole liner and extends to the exterior profile of the precast concrete manhole. The monolithic continuous bell sleeve liner assembly prevents ground water infiltration between the interface of the manhole liner and the precast concrete or around cast-in-concrete mounted gaskets not in continous bell sleeve assemblies.
