Photo Album: Straightening of a foundation in Cheneville, Qc

Mr. Billy contacted Systèmes Sous-sol Québec, because he had noticed several signs that the foundation of his house might have moved and that this could potentially become a big problem for his house. He did business with us in order to straighten his house as it was at its origin and to stabilize it permanently. The solution that was determined by Systèmes Sous-sol Québec was the insertion of support pillars in the ground of the interior of the house. The house was near a water's edge and a lot of obstacles were around the house such as a terrace, trees and bushes so doing the exterior work was not a solution for our client. The support pillars we used are made of steel and are driven deep into the ground to reach rocky ground or other stable layer of soil. This helps straighten the house and then stabilizes it.

Ground movement

This photo shows that there was movement in the ground under the house and that the bottom of the wall has shifted. Stair-shaped cracks in the corner of a wall usually mean the problem is getting worse.

Wall Crack

Here we see a major crack almost half an inch wide. This means the foundation moves and keeps moving as this crack has grown larger over time.

Pressure in the soil

A lot of pressure is in the soil around a house. The pressure varies depending on the type of soil, the level of humidity present, the depth, etc. When the pressure is so great in the ground that the wall of the house cannot take it, the wall begins to bend, crack or sink.
