Underpinning is the process of stabilizing an existing foundation. Often, older homes are in need of underpinning because the original foundation isn’t strong enough. When thinking of adding on or changing the use of a home underpinning may be necessary to support the added use. Sometimes, the soil properties change, nearby construction can cause fluctuations or shifts in soil.
One way to tell if your home is in need of underpinning are cracks, especially those wider than ¼” and diagonal. Other signs of a failing foundation are cracked or buckling walls or cracked concrete floors.
Helical Piles are an effective home underpinning when the traditional method is not possible. Using a two-man crew and a mini-excavator, this method of home underpinning is ideal in areas where the structure must withstand tension, winds, compression, vibration, and pretty much hurricane or tornadoes we feel in Central Florida. The structure can be leveled and the weight distributed on the pier and bracket system. Screw and bracket home underpinning is fast and less intrusive, keeping any noise and vibration of surrounding areas to a minimum.
When wanting to forego a footing altogether, the best method of home underpinning is the installation of Spreader Beams. Using this method, foundation specialists install a pile on either end of the affected wall. A reinforced concrete beam connects the piles allowing the brick and existing damage to be removed. To allow for greater loads, shorten the distance between the beams. Helical Pile home underpinning is faster, less disruptive, allows for high loads and suitable in restricted areas making it an ideal solution to foundation stabilization.
It is best for a structural engineer to assist in any underpinning methods to ensure they are completed properly. Contact Poly Foundation Solutions today to consult with our team of foundation specialists.
