Are you having structural problems due to a sunken footer? Most foundation failure results from soil-related problems such as expansive soils that expand and shrink with changes in the moisture content of the soil, poor compaction, overloading, excessive organic materials or erosion. These conditions create instabilities that can damage a home’s foundation as well as the rest of the structure. A1 Concrete Leveling and Foundation Repair can fix the problem without major replacement costs.
The QuadPower Piering System Is The Permanent Solution!
What is a Pier?
A pier is an engineered structural support that can be attached to the foundation at strategic points in order to stabilize and lift the structure. Traditionally, there have been two types of piers – Helical and Push Piers. A-1 Concrete Leveling and Foundation Repair has incorporated the best of both systems into the Quad Power Pier. A-1′s Quad Power provides the larger surface area of a helical, the greater depth of a push pier, and adds the strength of concrete encased in steel.
Pier installation comes in a variety of forms: interior, exterior, location augured, location excavated, and fully excavated. While all methods can be used to stabilize, in order to obtain optimum recovery the entire foundation should be excavated (to the top of the footer). This eliminates side friction and vertical load created by the pressure of the surrounding soil. It also allows for the foundation to be inspected, and permits the void created by the lift to be filled.
“Span” is the distance between piers. To accurately determine the correct “span” and pier placement, it is best to examine the condition of the foundation and evaluate the weight of the structure. By fully excavating the foundation, A-1 Concrete Leveling and Foundation Repair is able to inspect the condition of the foundation while reducing side friction and vertical load. This method, although more invasive, insures proper placement of piers and optimum recovery.
