Helical piers.Push piers.Driven to refusal.

Engineered foundation stabilization for Anchorage and Mat-Su Valley homes. Steel piers driven 18–60 ft through glacial till to bedrock refusal — engineered for seismic zone 4 and the 42" frost line.

The Anchorage Profile · Scroll to drive the pier

Every pier we drive
passes through this.

Anchorage homes built on the Bootlegger Cove formation or Cook Inlet drift settle when their footings sit above the frost line or on saturated silty clay. Our remedial program drives engineered steel piers through every stratum until the lead point refuses against weathered bedrock — typically between 22 and 60 feet depending on parcel.

Seven ways
we stop a house
from moving.

Every project starts with a soil-profile reading and ends with a written engineer's report. We don't guess. The repair is chosen from the ground up — not down from a catalog.

  1. 01

    Helical pier underpinning

    Galvanized steel piers with 2–3 helix plates driven hydraulically to ICC-ES torque refusal. The remediation of choice for settled footings on Bootlegger Cove clay or saturated silt.

    • 50,000 lb working load
    • 18–60 ft typical depth
    • Year-round install
    DEF-01
  2. 02

    Resistance push piers

    2-7/8" structural steel pushed through till to bedrock using the home's weight as a reaction. Used when load is high and access is good — common on full basement foundations.

    • 60,000 lb capacity
    • Bracket-mounted under footing
    • Verified with load test
    DEF-02
  3. 03

    Polyurethane slab lifting

    Two-part foam injected through 5/8" ports to lift settled concrete back to grade — driveways, garage slabs, basement floors. Faster than mudjacking, no curing time.

    • Cures in 15 minutes
    • Lifts 1/4 inch increments
    • Won't wash out
    DEF-03
  4. 04

    Basement waterproofing

    Interior drainage tile + sealed sump system installed below slab. Captures hydrostatic pressure that would otherwise heave or crack the basement wall.

    • Below-slab drain tile
    • Battery-backup sump
    • Transferable warranty
    DEF-04
  5. 05

    Exterior drainage correction

    Re-grading, gutter extensions, French drains, and frost-stable soil correction. The cheapest stabilization you'll ever buy — when caught before settlement begins.

    • Min 6 ft from foundation
    • 3-degree positive grade
    • Frost-stable backfill
    DEF-05
  6. 06

    Crawl space encapsulation

    Closed-cell polyethylene vapor barrier, perimeter insulation, and dehumidification. Stops vapor drive that swells joists and rots sill plates in AK humidity cycles.

    • 20-mil reinforced liner
    • R-15 perimeter foam
    • Air-sealed access
    DEF-06
  7. 07

    Structural crack repair

    Low-viscosity epoxy or polyurethane injection through surface ports to bond cracks structurally. Carbon-fiber straps where lateral pressure is the cause.

    • 1,200 PSI tensile bond
    • Carbon-fiber 100ksi
    • Lifetime guarantee
    DEF-07

What a typical
repair file looks like.

We're a young firm and don't yet have a body of public reviews. Instead — three real project files, names redacted, every number from the engineer's log. Same paperwork we'd give you.

Project field photo
File AK-24-0118Oct 2024Eagle River · settled NW corner

21 helical piers, 2-story residence

Site finding
Bearing soil saturated silty clay above till. Original footing 28″ — well above the 42″ frost line. Differential settlement 1.4″ at NW corner.
Outcome
Piers driven to 27 ft, torque-verified to 6,400 ft-lb. Recovered 1.1″ on lift survey. Engineer's report issued.

File AK-24-0207Jul 2024Spenard · garage slab

Polyurethane slab lift, 14 ports

Site finding
Settled garage slab from poorly compacted backfill at original construction. Voids confirmed by probe. Slab tilt 0.9″ across 22 ft.
Outcome
47 lb of two-part foam injected. Slab lifted back to grade in 1/16″ increments. Repour avoided — saved approx 78% vs replacement.

File AK-23-0942May 2023Hillside · stepped wall crack

Foundation crack repair + drainage

Site finding
Stepped diagonal cracks in basement wall, max 3/16″ width. Cause: positive grade reversed by mature landscaping. Hydrostatic pressure cyclic.
Outcome
Polyurethane injection on 7 cracks, 87 lf of French drain installed at perimeter. Re-graded to 3° positive. No further movement reported at 18-month follow-up.

Credentials · Paperwork before piers

Six pieces of paper
before we touch your house.

Foundation repair is permitted, inspected, engineered work. If a contractor can't produce these on request before mobilization, they probably shouldn't be in your basement.
