Experts in Drilling, Shoring & Ground Improvement

Pacific Foundation plans and executes geotechnical construction across a wide range of ground conditions and geotechnical challenges. Services include deep foundations, earth retention and shoring, ground improvement, seismic upgrades and groundwater control across the Pacific Northwest, Mountain West, and Hawaii.

GEOTECHNICAL CONSTRUCTION SERVICES

OUR CAPABILITIES

Pacific matches deep foundations, earth retention and shoring, ground improvement, and groundwater control methods to site conditions, access constraints, structural loads, groundwater, and project sequencing.

Drilled Shafts

Large-diameter cast-in-place foundations installed to transfer heavy structural loads through weak soils into competent bearing layers or rock.

Augercast Pile

Continuous-flight auger piles installed with pumped grout or concrete to provide efficient deep foundation support with limited vibration and noise.

Driven Pile

Steel, concrete, or timber piles driven to required resistance for dependable structural support across variable soil and groundwater conditions.

Micropile

Small-diameter, high-capacity drilled piles used where access, overhead clearance, difficult ground, or existing structures constrain conventional foundation equipment.

CDSM Soil Mixing

In-place soil is blended with cementitious binder to increase strength, reduce settlement, control groundwater, and improve excavation stability.

Jet Grouting

High-pressure grout creates soil-cement columns that strengthen weak ground, reduce permeability, and support or underpin existing structures.

Rigid Inclusions

High-modulus columns installed beneath foundations and slabs to reduce settlement and transfer loads through compressible soils into stronger materials.

Displacement Piles

Cast-in-place piles installed by displacing and densifying surrounding soils, producing strong foundation support with minimal spoil generation and vibration.

Soldier Pile Walls

Drilled or driven steel piles with lagging that provide adaptable temporary or permanent support for excavations and adjacent improvements.

Sheet Pile

Interlocking steel sheets driven into the ground to retain soil, control groundwater, and support excavations in constrained conditions.

Secant/Tangent Piles

Overlapping or closely spaced drilled shafts that form rigid earth-retention walls for deep excavations, groundwater cutoff, and limited-access sites.

Groundwater Control

Dewatering, cutoff, pumping, and drainage systems designed to manage groundwater while maintaining excavation stability, access, and construction progress.

Hoffman Construction Company Logo

“Pacific Foundation accomplished a “Herculean” task to complete drilling of 760 Micropiles and 174 steel towers to temporarily support the 80,000 tons dead load of the Capitol… Hoffman Construction would like to recognize your entire crew in achieving such a difficult task.
