HELICAL PILES FOR FOUNDATION REPAIR
Sinking foundations, cracked and buckled walls and uneven floors are problems commonly faced annually by some quarter-million homeowners. Homes and other structures situated on unstable soils settle when their foundations are subjected to extreme moisture conditions or lack proper drainage. A shifting foundation may result in structural damage to your home or building and a loss of your investment.
What to look for:
- Foundation walls that are buckled or bowed
- Doors and windows that stick or don’t open properly
- Cracks in foundation walls
- Cracks in exterior walls
- Cracks in interior walls and ceilings
- Sunken or buckled interior concrete floors
How Helical Piles WorkThe idea behind helical piles (screw piles) is to relieve the stress on these failing areas by drilling helical screw piles (see the illustration) into stable areas of soil until the necessary load bearing capacity is reached. Adjustable brackets are then attached to your foundation and the weight is transferred from your foundation to the screw piles. The structure can then be raised to its original state using the adjustable bracket.
HELICAL PILE Foundation Systems Advantages:
- A time-proven, versatile and technically sound system
- Lower cost — both for the system and its installation
- Faster installation than other methods
- Very limited excavation — site is minimally disturbed
- No heavy equipment required
- Installs in limited-access areas
- Used in new building construction to enhance foundation strength on sites with poor soil conditions
