ENGINEERED 
RETAINING
WALLS®

Call your insurance company first to open the claim and get a claim number — but also contact an engineer or qualified retaining wall contractor within the same 24–48 hours to document site conditions before they change. Failure evidence like soil displacement, drainage issues, and wall position can shift significantly in the days after a failure. Having both running simultaneously protects your claim from the start.

Adjusters need wide-angle shots of the full wall and surrounding slope, close-ups of every crack, separation, or zone of movement, documentation of drainage outlets (or their absence), soil blowouts at the base, any storm debris or tree strike evidence, and a slow continuous video walk-through of the entire failure. Date-stamp everything. The more clearly your photos tie the damage to a specific event, the stronger the claim.

Most retaining wall insurance claims take 4–12 weeks from first notice to settlement, though complex cases involving engineered rebuild scopes, disputed cause, or large dollar amounts can stretch to several months. Prompt documentation, a clear engineering report, and a detailed contractor estimate significantly speed up the review. If your adjuster is slow, following up weekly is appropriate and often necessary.

Insurance typically pays for what is necessary to restore safety and function to the pre-loss condition. Minor damage may be repairable, but structural movement, wall rotation, base loss, or collapse almost always requires a full engineered rebuild — because a patch on a compromised structure doesn't meet code and won't pass inspection. We document the structural condition and recommend the appropriate scope for your claim.

The most common denial reasons are: the adjuster determines the failure was caused by long-term drainage issues or soil settlement rather than a sudden event; the insurer cites lack of maintenance; or they claim the wall was defectively built. Each of these can often be countered with engineering documentation showing a clear triggering event, proper prior condition, and code-compliant original construction. Never accept a denial without reviewing the specific written reason.

Yes — in NC, GA, and TN, any wall over 4 feet tall or supporting a slope, driveway, or structure that is being rebuilt must have an engineered design and building permit before work begins. Inspectors will not approve a rebuilt wall without a licensed PE stamp on the plans and inspection sign-offs during construction. We handle engineering and permitting in-house, so our estimate and scope already account for these requirements.

Do only what is necessary for immediate safety. If blocks are creating a direct hazard, minimal movement is acceptable — but photograph their position first. Otherwise, leave the failure intact as long as possible. Before anything is moved, take photos and video from every angle and save any displaced materials on-site for the adjuster's review. Evidence that's been cleaned up before documentation is a common reason claims are underpaid.

A proper insurance estimate for an engineered wall rebuild should include: base excavation and soil removal, a full drainage zone with perforated pipe and stone, geogrid reinforcement layers for MSE walls, wall material and labor, access and safety staging costs for difficult-terrain sites, and engineering and inspection fees. Estimates that leave out drainage, geogrid, or engineering are red flags — they won't produce a code-compliant result and insurers may require a revised scope.

The strongest claims have three things: a clear trigger event (storm, flooding, slope movement) documented with dated photos and weather records; a licensed engineer's report identifying root cause and ruling out maintenance or pre-existing conditions as the primary cause; and a detailed contractor estimate that matches the scope the engineer recommends. ERWalls provides engineering-backed estimates formatted specifically for insurance review.

Get the adjuster's findings in writing, then submit your engineering report directly to the claims supervisor explaining the technical disagreement. If the engineer's analysis shows a covered cause and the adjuster's denial was based on a field opinion rather than engineering, you have grounds for re-inspection or appraisal. We've helped dozens of homeowners navigate this — an engineer-backed position almost always gets a second look.
