  • 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.
