Montreal Foundation Crack Repair


Is your concrete foundation cracked or leaking?  Most homeowners have encountered the frustrating problem of cracks in their foundation walls as well as the resulting stubborn water leaks that eventually find their way into your basement.  Unfortunately, many foundation crack repair techniques deal solely with covering the cracks with hydraulic cement, epoxy or sealer. When moisture eventually loosens the water soluble ingredients and expansion and contraction takes place, these quick fix solutions usually fail. We know that cracks will continue to move as warmer and colder weather causes continuous expansion and contraction of the structure.

There are two main kinds of foundation repair that we use; Polyurethane and Epoxy injection.  Without getting to confounding here are the basic principles we follow.

Polyurethane Injection: 

  • Flexible and allows for natural movement of the concrete due to thermal shrinkage and expansion.

  • Can be used to repair wet or even leaking cracks, it repels water.

  • Polyurethane crack injection expands over 20 times its volume.


Epoxy Injection:
  • Epoxy crack injection provides structural strength.

  • Strength and bond with concrete greatly exceed the strength of the concrete itself.

  • Only to dry surfaces, making the repair of a leaking or wet cracks impossible 

  • No expansion - a 1/4-inch crack needs four times more epoxy than a 1/16-inch crack.

  • Epoxy Crack Filler provides the strongest repair, which will withstand traffic.

We know that in attempting to waterproof your basement the first priority is to properly repair your foundation.  Just give us a call and our team of repair specialists will work with you to find the best and most cost effective method to achieve a successful, long lasting foundation repair.



Foundation interior Crack Repair

 

Step 1: Drill holes through the crack at a  45 degree angle               every 6 inches.

Step 2: Screw in injector plugs ( with Grease nipples to connect               the high pressure pumps).

Step 3: Flush out the crack with a mild acid to remove dust, dirt               and debris from one injector to the next (removal of               any obstructions for the injection).

Step 4: Flush out the crack with water to clean out the acid.                Water is also a reactor/accelerator for the               polyurethane.

Step 5: Cover the crack with hydraulic cement to prevent the               outflow of the polyurethane from the injection.

Step 6: Inject the polyurethane at 3000 to 10000 psi to fill all               the open voids in the concrete and to push through to               the other side.

    Step 1: Lay plywood on the ground around the work area to               keep the mess at a minimum.

    Step 2: Excavate one hole approx 3.5 feet by 3.5 feet to the              footing.

    Step 3: Scrape and clean the wall with wire brushes in               preparation for the repair.

    Step 4: Drill holes through the crack at a  45 degree angle               every 6 inches.

    Step 5: Screw in injector plugs ( with Grease nipples to connect              the high pressure pumps).

    Step 6: Flush out the crack with a mild acid to remove dust, dirt               and debris from one injector to the next (removal of               any obstructions for the injection).

Step 7: Flush out the crack with water to clean out the acid.                Water is also a reactor/accelerator for the               polyurethane.

Step 8: Cover the crack with hydraulic cement to prevent the               outflow of the polyurethane from the injection.

Step 9: Inject the polyurethane at 3000 to 10000 psi to fill all               the open voids in the concrete and to push through to               the other side.

Step 10: Remove the injector plugs and fill all the holes with                 hydraulic cement to have a smooth surface

Step 11: Apply our 3 signature membranes over the entire                 crack area

Step 12: Cover the area with an elastomeric membrane (Aqua                 block)

  • Adhere a rubber sticker (Blue skin) to the wall and seal the joints with the elastomeric membrane (Aqua  block)  

  • Install a drainage and protection board (Delta-ms) to protect the injection and the other membranes

Step 13: Carefully backfill the hole without damaging the                 membranes and by keeping all the big rocks away                 from the foundation

Step 14: Clean up the work area
