A leaning, bulging or shifting retaining wall is a symptom; the cause is almost always trapped water, failed drainage, or an undersized footing that has been heaving for years. Portland Concrete diagnoses the actual cause first, then repairs at the source rather than re-stacking blocks that are going to lean again. Some walls can be repaired in place; some need partial rebuild; a few need to come down entirely. Every assessment is free.
A leaning retaining wall is a story about water. The drainage stone behind the wall has clogged, the drainage pipe has failed or was never installed, the soil is now saturated, and water pressure is doing what the engineer warned about. Re-stacking the wall without fixing the drainage is a guarantee that the same lean comes back in a few years.
We start every wall repair with diagnosis, what is the wall doing (leaning, bulging, shifting, settling), what is the cause (drainage, footing, design), and what is the right fix (in-place repair, partial rebuild, full replacement). The honest answer sometimes is that the wall needs to come out and be replaced as a poured wall or block wall built right.
Same approach across the rest of our retaining wall work and our wider foundation repair service where similar root-cause-first logic applies.

How it works
How We Repair a Retaining Wall in Portland
Diagnose what the wall is doing
We assess the wall and the slope it retains, identify whether it is leaning, bulging, shifting or settling, measure how much, look behind for drainage issues, and identify the actual cause rather than the symptom.
Excavate behind the wall
Where drainage is the cause, we excavate behind the wall to expose the existing drainage stone and pipe, remove what has clogged or failed, and inspect the back face of the wall for damage that needs to be addressed in place.
Rebuild drainage and reset
New drainage stone goes in against the back face, a new drainage pipe is installed at the base routed to daylight, and any leaning sections of block are reset; poured walls that have moved get assessed for stay-or-go.
Backfill and monitor
The cut is backfilled with the drainage path intact, the wall is monitored after rain or melt to confirm the lean has stopped, and any longer-term watching is built into the project handoff.
When to repair vs replace
Some Walls Cannot Be Repaired Honestly
Repair is the right tool when the wall structure itself is sound and the cause (almost always drainage) can be corrected without rebuilding the whole wall. It is the wrong tool when the wall was undersized from day one, when the footing is wrong everywhere, or when the lean is past the angle a repair can pull back.
On every wall repair call we say which case the wall is in. If repair is throwing money at a doomed wall, the quote will recommend a fresh poured wall or block wall instead, built right with proper drainage and footing.
Leaning walls, drainage rebuild, when to repair vs replace and root-cause diagnosis.
Sometimes. If the lean is moderate, the wall structure is sound, and the cause is correctable drainage, repair can stop the lean and prevent it from getting worse. If the lean is severe, the structure is failing, or the cause is not correctable, replacement is the honest answer.
Because trapped water is almost always the root cause of wall failure. Re-stacking the visible part of the wall without fixing the drainage just buys a few years before the same lean returns. Fix the drainage first; the wall stays.
We measure the lean, inspect the back of the wall (excavating where needed), check the existing drainage, check the footing depth, and identify whether the cause is one issue or several. The repair quote follows the diagnosis.
Some excavation behind the wall is required to fix drainage, which means the yard above the wall gets disrupted. We restore the landscape after the repair, but expect a working zone of a few feet behind the wall during the project.
From a few days for a simple drainage rebuild to a few weeks for a partial wall reset. Diagnosis is usually a half-day; the repair scope drives the schedule, and the full timeline is in the written quote.

What Portland Homeowners Say About Their Wall Repairs
Three contractors quoted to rebuild the wall. Portland Concrete diagnosed it as a drainage failure, fixed the drainage, reset two block sections, and the wall has stayed put for two years. Fraction of the rebuild price.

Honest that our wall was past repair and a new one was the right call. Could have charged us for a repair that was going to fail. New wall is bombproof. Trust earned.

Drainage pipe behind our poured wall had collapsed years ago. They excavated, replaced it, monitored the wall through spring. No more bulging. Cause was the answer.

Diagnosis was free and detailed. Showed me exactly what was happening and what the options were. Picked the partial rebuild, exactly as quoted, exactly to schedule.
