Cracked concrete walls

For basement walls with cracks large enough to have water running through during spring thaw or after extended rainy periods, I recommend a professional basement home repair service. This repair may require injections of epoxy or polyurethane.

Note: Most concrete wall cracks are caused by pressure behind the wall, from ground pressure, hydraulic water pressure and/or frost behind the wall.

If you have any of the above, it would be best to excavate the entire area around the cracked wall.

Caution: Always protect excavated areas using poly sheets or proper sloping to eliminate any concern of caving in.

Perimeter drainage should be flushed and cleaned every 3 to 5 years. This is a very inexpensive process if a catchment sump is already in place. If there is no catchment sump in place, it is best to have one installed.

After excavation and repair of any perimeter drainage tile or pipe, power wash the concrete wall removing any residual on the surface. Allow to dry.

Spray asphalt primer sealer 12” either side of the crack.

Apply peel and stick membrane over crack, bridging crack by 6-8 inches on either side. Apply dimpled PVC membrane over repaired area.

Back fill area with Sandy Pit Run Gravel to ensure proper water drainage to perimeter tile or pipe.
