Segmental Block Retaining Wall

What This Service Involves

Segmental retaining walls use manufactured blocks that lock together and, for taller walls, tie back into the slope with geogrid reinforcement. This system is a workhorse for Puget Sound properties because it drains well and tolerates the ground movement our soils and quakes produce. A wide range of colors and textures lets the wall complement your home rather than look industrial. We build on a compacted base with a drainage core so water never accumulates behind the face. Taller installations are engineered and permitted to current code.

Benefits

Interlocking design flexes with soil and seismic movement; Built-in drainage core prevents water buildup; Wide range of colors and textures to match the home; Geogrid reinforcement allows greater wall heights; Durable, low-maintenance concrete units

Our Process

1) Excavate and compact a level base trench; 2) Set the first course precisely and check for level; 3) Stack courses, adding geogrid and drainage rock as engineered; 4) Cap the wall and backfill, finishing the surrounding grade

What Affects the Cost

Wall height and geogrid reinforcement needs; Block style and finish selected; Length and curvature of the design; Base preparation and drainage aggregate; Site access for material delivery and equipment

Best Time of Year

Best built in the drier months when base excavation and compaction stay firm, though shorter walls remain feasible into fall.
