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

Ground conditions, groundwater, and access constraints can define a project before construction begins. Pacific Foundation delivers the deep foundation, shoring, ground improvement, and groundwater-control work needed to support the structure and move the job forward.

Drilled-shaft illustration showing an auger inside a bored hole.

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 illustration showing an auger extending below ground.

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 illustration showing a hammer driving a pile.

Driven Pile

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

Micropile illustration showing a slender pile extending below ground.

Micropile

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

Deep cement mixing illustration showing rotating mixing paddles.

CDSM Soil Mixing

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

Jet-grouting illustration showing grout spraying into the ground.

Jet Grouting

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

Rigid-inclusion illustration showing columns beneath a supported slab.

Rigid Inclusions

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

Displacement-pile illustration showing a pointed tool pushing soil outward.

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 wall illustration showing lagging between vertical piles.

Soldier Pile Walls

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

Sheet-pile illustration showing interlocking steel profiles.

Sheet Pile

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

Secant-pile wall illustration showing overlapping piles.

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 illustration showing a pump connected below ground.

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.
