Helical & Push Pier Systems
When a Long Island foundation settles because the original footing sits on weak or poorly compacted soil, pier systems are the permanent engineered fix. Helical piers screw into stable strata below the problem zone and work well in the sandy soils common along Long Island's south shore. Push piers drive off the structure's own weight to reach deeper bedrock, making them the better choice in north shore clay conditions. We are a Supportworks-certified installing dealer, and every pier plan is PE-signed, load-tested to twice working capacity, and ICC-ES code-compliant. After installation, synchronized hydraulic jacks lift the structure back toward original elevation — doors close, cracks tighten, and floors level, typically over one to two days. The lifetime warranty transfers to new owners at no cost.

4 Steps. No Theatre.
Assess
Elevation survey at footing corners to quantify settlement. Soil boring or probe to understand what we're piering through.
Engineer
Pier count, spacing, and depth calculated from load and soil. PE signs the plan before we mobilize.
Install
Hydraulic drive to load-bearing strata, each pier recorded to capacity. Brackets bolted to footing.
Lift
Synchronized hydraulic lift returning the structure toward original elevation. Doors and cracks close in real time.
