Identifying retaining wall failure signs
Common signs of wall failure include forward tilting, horizontal bowing, cracked mortar, and bulging blocks. These issues stem from inadequate foundation gravel, missing deadman anchors, or poor groundwater drainage. We resolve these issues by installing proper drainage behind the wall.
Repairing versus replacing a wall
Minor block shifting or localized timber rot can often be repaired by resetting sections and replacing gravel. If the foundation footing has settled severely or soil has washed out behind, complete replacement is necessary. You can review all material pricing options in our complete cost guide.
Upgrading drainage during replacement
When replacing an old wall, we remove all trapped mud and old backfill dirt behind the structure. We install modern perforated drain pipe and clean crushed stone to prevent future hydrostatic pressure. We also build concrete block retaining walls for long-lasting performance.

People also ask
How do I know if my wall needs repair or replacement?
Leaning walls with intact footings can often be repaired, while cracked or collapsed foundations require full replacement.
Why did my existing retaining wall lean?
Most walls lean due to trapped groundwater building hydrostatic pressure behind an improper backfill layer.
How much does wall repair cost?
Repair costs depend on wall height, site access, and damage extent, so we price each repair after a site visit.
Do you haul away old broken wall material?
Yes, we remove and dispose of old decayed timber, broken concrete, or excess soil during replacement jobs.
You might also want drainage behind the wall and concrete block retaining walls, or see what these usually cost in the cost guide.
