In Burnaby, British Columbia, True Level Concrete was asked to lift and level a home that was not structurally sound. The 2-story home was sinking due to poorly compacted soils which caused the floors to slope. In fact, if you put a marble on the floor it would roll to the other side of the room! This was making the owners feel unsafe. The home sunk up to a full 6 inches on an addition of the home. Can you imagine how disconcerting that would be? Another sign of foundation settlement was the appearance of several large cracks at different locations along the foundation. To stabilize the home, True Level had to find a solution to bypass the unstable soils beneath the foundation. Anything other than fixing the soil problem would not be a long term solution.
Our solution was quick to install and caused very little disturbance to the existing structure. The whole project was supported and approved by geotechnical and structural engineers. To fix the tilted home, True Level installed 23 Supportworks push-pier systems to the underside of the exterior and interior foundation walls. These steel piles were then driven down to an average of 20 feet below the foundation footing until they hit solid bedrock. After the piles were driven, TLC used hydraulic rams to lift the house back to original heights where it was stabilized on the bedrock 20 feet below rather than on the problem soils directly beneath the foundation.
Once the house was lifted, True Level Concrete injected PolyLevel, which is a high density polyurethane expanding foam, to fill the new void beneath the foundation. The interior floor was also lifted and stabilized with our PolyLevel system.
