Freeze / Thaw Damage

Ottawa's freeze and thaw cycles can put pressure on foundations. As water freezes, expands, and melts, it can contribute to cracks, movement, and surface damage over time.

Clay Soil Movement

Clay soil can expand when wet and shrink when dry. This movement can place pressure on foundation walls and contribute to cracking, shifting, or settlement.

Poor Drainage

When water does not drain properly away from the home, it can collect around the foundation. Over time, this can lead to basement leaks, soil movement, and added pressure against foundation walls.

FAQ's

Questions homeowners usually ask.

Concrete aging. Concrete takes about 40 years to fully cure. The older it gets, the harder it gets, making it more prone to cracking. The only guarantee with concrete is that it is going to crack — it’s just a matter of when.

Foundation waterproofing should be done when the infiltration of water is observed, or as a preventative measure.

By managing the water before it can come in. This can first be done by managing the source of the water. Remedies can include isolating and waterproofing cracks in the foundation wall, fixing a clogged weeping tile, adding a sump pump, fixing negative grading issues, and more.

Waterproofing is done when the structural integrity of the foundation is suitable to continue supporting the house but just needs a system to keep water out from fissures in the wall. When the foundation has lost its structural integrity, a more in-depth structural repair following engineered drawings is needed to bring the wall back to structural load-bearing capacity.

A good foundation repair should last the lifetime of the structure.
