Retaining walls · Grading · Drainage · Leveling

Walls that hold the hill.

Sloped yard? Wet basement after a hard rain? We grade the property, install retaining walls where the slope is fighting you, and route drainage away from the house.

Most retaining wall failures come from skipping the boring parts — drainage behind the wall, proper base depth, the right backfill. We don't skip the boring parts. Engineered systems for walls over 4 feet; segmental block systems for everything else.

Sloped yards, made usable.

What we solve

Terraced backyards

Two or three retaining-wall steps to turn an unusable slope into level usable space — patio, lawn, garden tiers.

Walkout basement protection

Wing walls + grading that keep water moving away from a walkout, not into it.

Driveway widening

Cut into the side of a slope, retain it, widen the driveway by 4–6 feet.

Drainage rescue

Wet basement, soggy lawn, eroding slope. Re-grade the yard, daylight a drain, fix the problem at the source.
