A hole is dug into the floor and the Sump Liner is inserted so that the top has just enough space to the lid above the floor level.

Concrete is then poured over the gravel and bringing the floor back to level and still allowing full access from the lid at the top to access the TripleSafe Sump Pump for annual service and maintenance.
