Earthwork that
earns its energy spec.
Foundation systems and site prep for the builders, architects, and owner-builders specifying high-performance envelopes across Anchorage and the Mat-Su.
01
ICF foundation excavation
R-50 continuous
Footing excavation, drainage stone, and bracing prep for insulated concrete form pours. Tight tolerances on plumb so the form courses stack square.
0.25" plumb toleranceQuote ready in 5 days
02
Frost-protected shallow foundations
FPSF / IRC R403.3
Shallow slab with horizontal and vertical skirt insulation. Cuts excavation volume 50–70% on suitable lots while meeting AK frost-depth code.
16–24" dig depthQuote ready in 5 days
03
Geothermal loop trenching
Horizontal / vertical bore prep
Trenching for 4–6 ton residential ground-source heat pumps. Coordinated with the loop installer for proper pipe burial depth and backfill.
4–6 ft burialQuote ready in 5 days
04
Site pad engineering & compaction
ASTM D1557 modified Proctor
Engineered fill in 8” lifts, compacted to 95% modified Proctor. Compaction tests at every lift on slab-on-grade and shop foundations.
95% compactionQuote ready in 5 days
05
Septic system installation
AK DEC standards
Tank set, leach field excavation, and final cover. Built to Alaska DEC residential septic spec with permit coordination.
DEC-compliantQuote ready in 5 days
