Commercial structures, warehouse distribution centers, retail strips along Capitol Boulevard, and multi-family apartment complexes in Olympia face intense structural demands. When heavy commercial footings settle on soft alluvial soils or reclaimed marine fill around Budd Inlet, structural settlement compromises building safety, elevator shafts, and municipal occupancy permits.
Unlike light residential structures, commercial foundation remediation involves massive live and dead structural loads. Underpinning commercial foundations requires precision geotechnical calculations, structural engineer stamped plans, and heavy industrial hydraulic tooling.
Olympia Foundation Repair Pros provides engineered deep foundation solutions for commercial assets across Thurston, Lewis, and Pierce Counties. Our core underpinning technologies include heavy-gauge round-shaft helical piles, high-capacity resistance push piers, and drilled micropiles.
Helical piles feature high-strength steel shafts with welded circular flighting (helixes). Specialized high-torque hydraulic drive heads advance the piles into the soil like giant screws. By monitoring installation torque in real time, our engineers correlate mechanical resistance directly to exact ultimate load-bearing capacity, ensuring every pile meets structural specifications.
For retaining walls, basement shoring, and marine bulkheads suffering from lateral soil movement, we install helical tiebacks. These horizontal anchors are drilled deep through concrete walls into stable embankments, tensioned to engineer specifications, and secured with heavy steel wall plates to permanently arrest lateral deflection.
