Foundation Work

A building is only as good as what it sits on, and in Alaska, that means foundation work requires extra care and expertise. MNA Construction provides complete foundation support services — from initial excavation to footing preparation, structural backfill, and final grading. We dig to the depths required by Alaska's building codes, which demand footings well below the frost line to prevent heaving and structural damage.

Our foundation crews work on everything from simple crawl-space residential foundations to full basements and large commercial slab-on-grade projects. We excavate to precise dimensions, provide compacted granular pads for footings, install perimeter drain tile systems, and handle waterproofing backfill with free-draining material. For projects on challenging soils, we work with structural engineers to implement solutions like over-excavation and replacement, helical piers, or thickened edge slabs.

Retaining walls are another area where our Alaska experience pays off. Whether you need a structural retaining wall to create a level building pad on a sloped lot or a gravity wall to stabilize a road cut, we build walls engineered for the lateral earth pressures and frost forces specific to our region. We work with segmental block, cast-in-place concrete, and treated timber systems depending on the application and budget.
