Resistance piers, or steel push piers, are one of the main products that we use to lift foundations in the Bay Area. These products are installed underneath existing foundations that have started to sink to lift them back to the proper level. Here at Bay Area Underpinning, we rely on high-quality steel resistance piers from ECP (Earth Contact Products).
Have you noticed your foundation settling or sinking? Normally, this is due to soil movement under your foundation. During dry conditions, the soil will shrink, leaving voids under the foundation. During wet conditions, the soil expands and can push on the foundation. As the soil expands and contracts, it can shift the foundation above, causing it to settle further into the ground.
When this happens, you need a foundation pier that can drive deep into the ground past the active soils to lift the foundation. The Model 300 piering system from ECP is becoming well-known as one of the strongest and deepest driving piers in the industry. The expert foundation repair crew at Bay Area Underpinning can install these piers to raise and stabilize your pier in California. If you see signs of foundation failure in your home, such as foundation cracks, foundation settlement, misaligned doors and windows, wall or ceiling cracks, or porch and stoop issues, call us today.

These are just some of the benefits that our ECP resistance piers offer. The flexibility of the piering system allows them to be used in a variety of different foundation lifting situations. The resistance piers used by Bay Area Underpinning are a two-step system, meaning that it uses hydraulics after it is driven into the ground. First, the piers are driven into the ground until they reach a solid layer of soil that can bear weight without moving. This means that they must be driven in far enough to anchor underneath the active, moving soils. Next, the hydraulic lifting system is activated to raise the foundation.
Because the piers are end-bearing, they do not rely on friction to support the above structure. In addition, the friction reduction collar on the piers reduces any friction to help installers verify when the piers reach the load-bearing soil layers. Each pier is carefully load-tested before installation to ensure that it can bear the foundation.
