Foundation Underpinning
FOUNDATION UNDERPINNING — STOP SETTLEMENT, RESTORE LEVEL
Underpinning stabilizes and lifts settling foundations by extending support to deeper, more stable soil layers. Methods include steel push piers (driven to bedrock or stable strata), helical piers (screwed into stable soil), and mass concrete underpinning (excavate and pour beneath existing footings). We assess the cause of settlement, engineer the pier layout, install piers to required capacity, and lift the foundation back to level where possible.
Key Highlights
Push pier systems
steel piers driven through unstable soil to bedrock or competent bearing strata.
Helical pier systems
screw piers for lighter structures and interior underpinning applications.
Foundation lifting
hydraulic jacks on installed piers can lift settled foundations back toward level.
Why Choose Our Foundation Underpinning
Foundation settlement is progressive — it doesn't fix itself. Underpinning addresses the root cause by extending support to stable soil layers below the problem zone. We assess the settlement pattern, determine the cause, engineer the pier layout, install piers to verified capacity, and lift the foundation where possible.
Signs You Need Foundation Underpinning
1. Cracks in walls and ceilings
Diagonal cracks at window and door corners, stair-step cracks in masonry, or ceiling separation indicate settlement.
2. Doors and windows sticking
Frames racking out of square from foundation movement cause doors and windows to bind or not close properly.
Our Process
Step 1 — Assessment
Evaluate settlement pattern, interior and exterior cracking, and floor levelness.
Step 2 — Pier installation
Install steel push piers or helical piers at engineered locations to verified capacity.
Step 3 — Lift and stabilize
Use hydraulic jacks on piers to lift the foundation toward original position and lock brackets in place.

FAQs About Foundation Underpinning
Can a settled foundation be lifted back to level?
In many cases, yes. Push piers and helical piers can be used with hydraulic jacks to lift a settled foundation back toward its original position. The amount of lift achievable depends on the building construction, the amount of settlement, and the condition of the structure above. We provide honest expectations during assessment.
