Why did the customer contact us?
The customer said that the basement is constantly flooding. She said she did purchase a sump pump a few months ago but it burned out. She is interested in a new sump pump and also waterproofing her basement.
Solutions provided:
Small basement had 24 inches of standing water. Existing sump pump was not functioning properly, excessive leaves and sediment in existing, open crock. Once dewatering was completed water was entering floor from weep holes drilled in concrete block wall and from blocked drain box outside and into basement under door. Drain was blocked due to leaves. Water has reached a maximum height of 36 inches as evidenced by the wet line on the block wall.
Due to severe conditions in the small basement the following is needed.
Full GrateDrain system around perimeter of basement.
1: Use jackhammer to remove floor only, from out 9 inches from inside edge of footer.
2: excavate down to just below underside of floor.
3: Install GrateDrain system and backfill with washed type 56 stone.
4: Drill additional weep holes along entire perimeter to permit water to enter FlexiFlange along wall, up 12-16 inches, seal to wall with fasteners and finish seal adhesive.
5: Cover with high strength concrete and finish flush with floor.

3: To supplement existing GrateDrain, install SpeedE channel across doorway inside of door, past threshold and tie into GrateDrain system below
