Since the early 1800’s, contractors and engineers have been using helical piers and helical piles in foundation repairs. They are used to stabilize your sagging and shifting home. They were originally made with a wooden shaft and iron helix and were used mainly in lighthouse foundation repairs. Fast forward to today, and we see helical piers being used in almost every foundation repair. They are one of the two most common designs for structural piering repairs in homes. They are most sought after choice when a repair for stabilization of a light structural load is present. Also, in unstable rock foundations and when very deep load bearing stratums are present.
Helical piers are installed in the foundation of your home but the signs of needing them are much easier to spot then going underground to look. Indicators to look for if you need Helical Piers in California are cracks in walls exterior, doors and windows that are not opening/sticking, and if your chimney is pulling away from the home. If you notice of these signs it would be wise to consider having a professional take a look and see. It’s better to have it checked on earlier because then it can’t grow into a larger dilemma. Bay Area Underpinning utilizes helical piers from Earth Contact Products. These are the very best in underpinning products on the market today.
With the type of installation process that we use, the helical piers can be installed year round and only require small equipment, so we will not be causing as much disturbance to your home and its surroundings. We take our time to cautiously map out the area and find the best way to approach the problem to install your helical piers. They are mechanically installed by screwing them deep into the soil. We closely monitor the installation to assure optimum capacity. Once we have them at their capacity location, we will install and attach a underpinning steel foundation bracket to the piers. In a carefully maneuvered switch, the weight of your home is transferred onto the piers and then onto the soils below. This will ensure no future sagging and shifting of your home and give the possibility of your home being lifted to it’s original building position.
Helical piles is another name used for helical piers. These helical piles are driven deep into the ground through the unstable soil layers until they reach a more solid soil layer. Each helical pile is individually load tested. After load testing, the entire weight of the structure is lifted onto these helical piles using hydraulic jacks. There are many advantages of using helical piles for foundation repair such as:
Helical piles are ideal for application where there is a need to resist a tension, compressive force or both.
