Interior Drain Tile

A drain tile system relieves hydrostatic pressure and channels problematic ground water to a sump pump, where it is safely discharged away from your foundation.

1. A trench is dug and drain tile is installed next to the footing, pitched toward the sump

2. Weep holes relieve water pressure on walls by drilling a hole in every core and seam of a block wall.

3. 3/4" river rock acts as an added filter to keep "fines" like sand and silt out of the drain tile. In this image, the discharge line from the sump is laid in the trench and will be hidden once the new concrete is laid.

4. Dimpled drainage board covers the weep holes and channels water to the drain tile system.

5. Afer the cement cures, the wall is ready to be refinished.
