Brewers Creek Peat Settlement

Owners of this Vancouver home called True Level Concrete when they noticed their house was in need of foundation repair. TLC took measurements and noticed a 20″ slope from one side of the house to the other. If you were to look at the house from the street, you could see that the house was off-level. This happened because the house was built on a peat bog, which meant that the soils beneath the foundation were shifting constantly and unable to support the home. Other houses in the area have similar settlement issues. The foundation was strong and in excellent condition but because of bad soils had sunk and tiled 20″ towards one corner. The house was unsafe and needed to be stabilized.

Solution

The Geotechnical & Structural engineers recommended True Level Concrete to lift and stabilize the sunken areas of the house. The push piers supplied by Supportworks¬†were made of galvanized steel to prevent corrosion. For this home, True Level dug a trench around the perimeter of the house for the push piers to be installed and then 22 individual piers were then driven 50 feet into the earth until they each hit load-bearing bedrock. Then, with a hydraulic lifting station, TLC used the piers to lift the house 20″ back to original heights. The foundation is now level and all of the customers were thrilled with the result.
