Exterior french drain with the use of membrane is the number one solution to prevent water infiltration.

 

 

The process is as follows.

• The foundation walls are first excavated, then cleaned with high powered pressure washer and dried.

• Any damage to the foundation is repaired using hydraulic cement, epoxies and rebar.

• Aqua block 720 waterproofing membrane in then applied (installed) and left to dry to form a rubber coating over the foundation walls.

• Geo textile is then applied at the footing.

• The French drain (weeping tile) is then installed around the footings.

• Core thru footing in desired area for the installation of the sump pit.

• Break concrete floor for sump pit install. (inside basement)

• Install sump pump for the discharge of any waters.

• Platon (dimple board) is then fastened to wall with a pneumatic nail gun, then sealed with moldings and polybitume (waterproofing caulking membrane) to ensure no water infilitration.

• 24 inches of ¾ clean gravel is then placed with an additional layer of geo textile on top to prevent contamination of the drain.

• The area is then backfilled and graded. Excess backfill is removed and the area is then cleaned.
