Homes all over the country are settled on varying types of soil conditions. Some have rocky foundations while others are settled in very sandy soil. These differences naturally lead to the need for appropriate foundation repair solutions. Three of the most common foundation repair techniques include resistance or push piers, helical piers, and bell bottom piers.
Resistance or “Push” Piers
Resistance piers are great for lifting heavy structures. If the soil underneath a home is inadequate, this type of pier is pushed into the ground until it reaches a load-bearing surface. At this point, the support tool acts as a counter-force that lifts heavy structures such as a single-story home and heavier construction. The systems are installed in two steps: First, the pipe is driven until it reaches the bearing stratum; second, the lift equipment and a manifold system lift the structure.
Helical piers are valuable for powerful support while construction workers complete foundation repairs. These steel shafts look a lot like a corkscrew. The corkscrew blades rotate into the ground, keeping the pier in place and providing plenty of downward pressure and outward force. These piers are often used in tieback applications. They are chosen for projects including retaining walls, pre-construction, hillside structures, and concrete patios. Before settling on these piers as an option, however, it’s crucial to have an expert test the soil to ensure the right amount of soil strength.
Bell Bottom Piers
Finally, bell bottom piers are on option. These piers are constructed from a combination of concrete and rebar. The concrete is poured into a bell-shaped “foot”. This new shaft is then located deep underground. The specific size of the pier, depth in the soil, and location are determined by the construction of the home.
Remember that foundation repair options depend a great deal on the type of geographic conditions of the worksite. If you’re considering repairing the foundations of your home, work closely with a professional to determine the best option for your area.
