Waterproofing & Foundation Repair

Description

We use outside and inside (see drain tile page) applications. The outside application requires excavating, straightening walls, repairing cracks, applying rubber membrane to cracks, applying foundation coating to walls and 2 layers of 6 mil plastic. Then, installing new drain tile, covering with clean rock, installing new window wells, and backfilling with grading to drain water away.

STEP 1

Waterproofing - Using the backhoe

The walls are excavated using the backhoe.

STEP 2

The walls are cleaned with wire brushes to remove all dirt. Then a propane heater is used to dry all moisture from the wall.

STEP 3

Waterproofing - Sealing the cracks

All cracks are patched using a rubber membrane.

Waterproofing - Coating the wall with tar

The wall is then given a THICK coat of tar.

STEP 4

Waterproofing - Installing 6 mil plastic

Two layers of 6 mil plastic are placed over the tar.

Waterproofing - Installing verticle pipes

Three inch perforated pipe is placed vertically along the walls at all window wells. A 3 inch draintile is also placed along the footing and covered with gravel. This pipe drains exterior water into the sump pit, floor drain, or natural drain.

STEP 5

Waterproofing - Backfill and graded

Finally, the trench is back-filled and graded out.

 

THE INSIDE application consists of sawing the floor one-foot out from the basement walls, removing the concrete, excavating, installing drain tile and covering with clean rock. The drain is connected into the sump pit, then the concrete is replaced.
