Retaining Walls
Retaining wall construction for properties where elevation changes require thoughtful planning, drainage and durable site improvements.
The work
What this service involves
A retaining wall can help create usable space or support a change in grade, but wall design depends on height, soil, loading and water conditions. Structural requirements and permits should be established before work begins.
Serving Beaverton, Clackamas, Salem and surrounding Willamette Valley communities. Work is evaluated by scope, schedule and applicable licensing.
Scope & considerations

Drainage behind the wall

Questions
Frequently asked
Does a retaining wall need engineering?
Depending on location, height and loads, engineering or permits may be required. Applicable requirements should be checked with the local jurisdiction.
Will a wall fix a drainage problem?
A wall and a drainage solution serve different purposes. Water management should be evaluated as part of the overall site plan.
Can you estimate a wall from a photo?
Photos help with an initial conversation, but final scope and pricing often require dimensions and a site assessment.
