Rock and block retaining walls in Maple Valley, WA
DDB builds rock and boulder retaining walls, along with traditional block retaining walls.

Retaining walls
What's included
Because the same crew does the excavation and grading, the wall goes in as part of the dirt work: cut the slope, set the rock, finish the grade.

Dorien and his team did a great job on a driveway/open area project. Super efficient. Had the land cleared and prepped in one day! Very impressive.
