Any contractor can tell you that a structure is only strong as its foundation. Deep foundations transmit the structure’s load to soils that are deeper in the ground. A deep foundation is used when a shallow foundation is not possible, not practical, or will not carry the load, such as in weak, unstable, or expansive surface soils. Proper site preparation and installation is key to the success of any job – starting with the foundation.
When building a new home, short-term decisions usually include what floor tile to use in the kitchen or which coverings to put on the living room bay windows. Few homeowners think about which type of foundation offers the best long-term stability.
With residential remedial foundation repair becoming a greater concern, the CHANCE® helical pile was developed in the mid-1980s and was issued a helical underpinning methods patent in 1992. This all sounds well and good, but the question remains: Why are helical piles so effective for remedial foundation repair?
