Raised Floor Drainage Systems

This approach is called for when we determine a standard closed pressure relief system below the slab will actually be below the water table, thereby channeling too much water to the sump pit, causing the sump pump to run continually.

In this case, we raise the entire closed pressure relief system so that the drainage pit rests at the highest point of the water table. The system, and sump pit(s), are installed at the new elevation. We then cover the entire subfloor with a dimpled membrane and pour a new 4” concrete basement floor.
