A qualified underpinning contractor will determine the best method to repair your home. Here are some common methods:
• Mass Pour - This method extends the surface area of the foundation by digging holesaround the structure and pouring concrete.
• Screw Piles and Brackets – Screw piles are installed around the perimeter of the foundation. A hydraulic jack is used to shift the foundation into the proper position.
• Piled Raft – Piles are inserted inside the building. Reinforcing steel needles are placed to bear the wall’s load. Next, a ring beam is installed to link the needles. Concrete is poured to reinforce the new structure.
• Pile and Beam – Piles are driven at regular intervals along the foundation walls. They are connected by concrete or steel needles which are drilled through the walls.
How Much Does it Cost?
The cost of underpinning depends on a number of factors. The consistency of the soil, condition of the existing foundation and the size of the work area must be considered. Each repair technique has a specific cost as well.
