From boulder retaining walls that hold a hillside to concrete walls, dry-stack stone, granite steps, and boulder seawalls that armor a shoreline, we build walls and stonework that solve problems and look like they've always been there.

Our Approach

Walls That Hold

A wall fails for one of two reasons: bad base or bad drainage. We build for both. Excavation goes below frost line, base material is sized and compacted, and weeps and drainage stone go in before the first course — whether we're stacking boulders, dry-laying natural stone, or pouring a concrete retaining wall.

For boulder walls, we source local stone sized to the wall's height so it carries real load, not just decoration. For dry-stack natural stone walls, we set the batter and tie courses correctly so the wall locks itself together. For poured concrete retaining walls, we coordinate the forms, rebar, and drainage to the engineered design.

Stonework

Granite Steps

Solid granite, set right. We install granite steps on properly compacted, frost-resistant bases so they stay level, true, and beautiful through every Maine season.

The difference between a set that lasts and a set that shifts is what's underneath: proper excavation depth, frost-resistant base material, meticulous compaction in lifts, and finish-grading that moves water away from the steps rather than pooling against them.

Shoreline

Seawalls & Shoreline Stabilization

Waterfront ground is the toughest ground we work. We build boulder and riprap seawalls that armor a shoreline against wave action, ice, and runoff — sized and keyed so the water works against the stone instead of behind it.

Shoreline work in Maine touches protected resources, so we build to permitted, engineered plans and coordinate with your engineer through the Maine DEP Natural Resources Protection Act and local Shoreland Zoning review. Our crews include team members certified by the Maine DEP in Erosion Control Practices — the standard the state requires for soil-disturbing work in the Shoreland Zone. Done right, the bank stops moving and stays that way.
