Basement Waterproofing

  1. Protect work areas with tarps
  2. Excavating the located area down to the footing level of the building (which holds up the walls of the building), and expose the footing and wall ready for waterproofing application.
  3. Cleaning the wall, repairing cracks by grinding them out into a “v” and repair with hydraulic cement, applying a parging mix (meant to coat a water-resistant barrier)
  4. Applying foundation aqua bloc.
  5. Applying fibre mesh (yellow jacket) for reinforcement and then another coat of aqua block and polyurethane (four-millimetres thick) for additional protection.
  6. Installing Delta MS drainage membrane (made of long-lasting polyurethane and recyclable materials, another added feature which keeps your basement dryer) with delta clips, finishing the moulding along the top with tapcon screws.
  7. Removing old weeping tile and install new “Big O” weeper with filter and connect to the existing weeping tile pipe.
  8. Encasing weeper (which sits on the soil) with ¾” clear gravel (one foot of gravel above the weeper), and then install a filter on top to separate gravel from soils.
  9. Backfilling and compacting the ground every two feet until backfilled.
  10. Installing gravel finish, clean work areas and remove access debris from the site.
