Retaining Wall Repair in Washington & Oregon
A leaning, cracking, or bowing retaining wall could be a structural issue. We repair and reinforce failing walls before they get worse.
Signs your retaining wall is failing
Retaining walls typically fail gradually. The slow lean or hairline crack you've been watching may worsen as the wall can no longer withstand the soil pressure behind it. These signs say it could be time to act.
Wall bowing or tilting
A wall that's no longer plumb, visibly leaning away from the slope, is actively failing. Soil pressure is exceeding the wall's capacity.
Horizontal or diagonal cracks
Cracks running horizontally or diagonally through a concrete or block wall mean it's in flexure and bending under the load of the soil behind it.
Sections that have shifted or fallen
If part of the wall has moved out of plane or collapsed, the remaining sections are now carrying more load than before. This can be urgent.
Soil eroding from behind the wall
Washout, sinkholes, or soil displacement behind the wall means water is moving through the fill and could be accelerating the pressure and erosion cycle.
Any movement on a wall over 3 feet
The taller the wall, the more soil it retains and the greater the force on it. Any movement on a wall over 3 feet is worth an inspection. Under 3 feet we typically recommend a landscaping partner.
Water staining or poor drainage
Persistent dampness, efflorescence, or water weeping through the face means drainage behind the wall has failed, a leading driver of wall failure.
Is your wall structural or landscaping? Height and material are the tells. Walls over 3 feet, concrete, or CMU block are usually structural. Feel free to book a free inspection and we'll tell you which category yours falls into.
What causes retaining walls to fail?
Retaining walls fail for predictable reasons. In almost every case, the wall is being asked to do more than it was designed for, either because conditions changed or it was undersized to begin with.
Hydrostatic pressure
Water that can't drain through or around the wall builds up behind it and multiplies the soil pressure it must resist. Walls with poor drainage fail faster.
Original design and construction
Many residential walls were built without engineering review, especially older or landscape-grade walls. They look fine for years, then reach their limit.
Soil loading changes
A deck built above the wall, a car parked near it, or a slope that's gotten steeper all increase the load beyond the wall's original design.
Age and material deterioration
Concrete, block, and timber all degrade over decades, mortar fails, concrete loses tensile strength, timber rots, leaving the wall weaker than it looks.
How Ram Jack West fixes it
The key questions at inspection are always wall height and material. Walls over 3 feet, and any solid concrete or CMU wall, are in the structural scope for us. Some shorter walls with serious structural concerns near a building or on a steep slope also qualify. We'll tell you plainly which category yours is in.
✓ Structural repair of walls over 3 feet. wall anchors, tiebacks, and reinforcement syste
✓ Case-by-case assessment of shorter walls with structural concerns near buildings or on steep slopes.
✓ Drainage assessment to tell you if the wall's drainage needs to be addressed as part of the repair.
✗ Walls clearly under 3 feet made of removable landscape block a landscapin-contractor scope. We'll refer you to the right partner.
Our process
Four steps. We stabilize the wall and address the drivers of failure, so your failing retaining wall stays put.
Schedule
Book your free on-site evaluation online or by phone. No commitment required.
Inspect
A specialist assesses height, material, movement, and the drainage behind the wall.
Repair
We anchor and reinforce to restore the wall to stability. In some cases, we can shift retaining walls back to plumb; if not, we can always permanently stabilize them.
Warranty
Lifetime transferable warranty on Ram Jack helical tie backs, and best-in-class warranties on carbon fiber solutions.

Common questions
Real questions property owners ask, answered directly.
How do I know if my retaining wall is structural?
Height and material are the two main indicators. Walls over 3 feet, poured concrete, CMU block, and any wall near a structure are typically structural. Walls under 3 feet of removable landscape block are usually landscaping scope. When in doubt, book an inspection and we'll tell you clearly.
Can a retaining wall collapse without warning?
Yes, the rate of movement or change is the most significant indicator. A retaining wall that has leaned slowly for years can reach a tipping point and go from stable to failed quickly. If yours is actively moving, don't wait.
How much does retaining wall repair cost?
It varies with wall height, length, material, and the method required. A free inspection gives you exact pricing.
My wall is under 3 feet — can you still help?
Possibly. If it's near a structure, on a steep hillside, or there's a serious structural concern, we'll evaluate it. If it's landscape block that just needs resetting, we'll point you to the right contractor.
