Pier & Pile Foundations
PIER & PILE FOUNDATIONS FOR CHALLENGING SOILS
Pier and pile foundations transfer structural loads through weak surface soils to stable bearing strata below. We install drilled concrete piers (caissons), driven piles, and helical piers with grade beam connections for commercial buildings, bridges, retaining structures, and residential projects on poor soils. Pier sizing and depth are engineered based on soil borings and structural load calculations.
Key Highlights
Drilled piers (caissons)
bored into stable bearing strata for heavy structural loads.
Helical piers
screw-type piers for additions, decks, and underpinning on soft soils.
Grade beam connections
reinforced concrete beams connecting pier tops to support the structure above.
Why Choose Our Pier & Pile Foundations
When surface soils can't support standard footings, pier foundations transfer loads to stable soil or rock below. We install drilled concrete piers, helical piers, and grade beam systems engineered for your specific soil conditions and structural loads. All pier work is based on soil borings and structural engineering.
Signs You Need Pier & Pile Foundations
1. Poor soil conditions
Geotechnical investigation reveals soft, expansive, or organic soils that can't support conventional spread footings.
Our Process
Step 1 — Soil investigation
Review geotechnical borings and structural load requirements to design pier layout.
Step 2 — Pier installation
Drill, drive, or screw piers to specified depth and capacity.
Step 3 — Grade beam
Form and pour reinforced concrete grade beams connecting pier tops.

FAQs About Pier & Pile Foundations
When are pier foundations needed?
Pier foundations are needed when surface soils have low bearing capacity (soft clay, organic soils, fill), when the building loads are too heavy for conventional footings, or when building near water or on slopes where shallow foundations aren't practical.
