Municipal Retaining Wall Construction

What This Service Involves

Grade changes along public trails, roadway shoulders, and park sites often demand structural retaining solutions. We construct segmental block, cast-in-place, and rockery walls to engineered drawings with proper drainage and geogrid reinforcement. Saturated Puget Sound soils make subsurface drainage design critical, and we build to prevent the hydrostatic failures that undermine cheaper installations. All work carries the bonding, engineering coordination, and prevailing wage compliance public projects require.

Benefits

Stabilizes slopes and prevents costly erosion and roadway undermining; built to stamped engineering with geogrid and drainage per plan; handles saturated Puget Sound soils that fail undrained walls; segmental, cast-in-place, or rockery options to match site aesthetics; engineered submittals and inspection coordination included

Our Process

1) Geotechnical and drawing review with drainage design confirmation; 2) Excavation, foundation preparation, and base leveling; 3) Wall unit placement with backfill, drainage rock, and geogrid layers; 4) Cap installation, backfill compaction, and drainage outlet verification

What Affects the Cost

Wall height, length, and engineered reinforcement requirements; excavation depth and soil bearing conditions; drainage system and backfill material specifications; wall system type and cap or facing selection; site access for heavy equipment and material delivery

Best Time of Year

Dry summer conditions keep excavations stable and allow proper compaction of engineered backfill.
