Retaining Wall Repair in Montgomery, AL

Retaining walls are common on Montgomery, Alabama properties with sloping yards. These

walls hold back soil, preventing erosion and protecting foundations. Over time, retaining walls

can crack, lean, or fail completely. Retaining wall repair restores their function and prevents

foundation damage.

Why Retaining Walls Fail in Montgomery

Retaining walls fail for several reasons in Montgomery. Poor drainage behind the wall allows

water to build up, increasing hydrostatic pressure. The expansive clay soil behind the wall

swells when wet, pushing the wall outward. Tree roots can displace stones or blocks. The

wall’s footing may settle into the clay. And freeze‑thaw cycles (though mild in Alabama) can

crack concrete. Montgomery Foundation Repair Co inspects the entire wall system to diagnose

the cause of failure.

Signs Your Retaining Wall Needs Repair

Look for these warning signs: the wall is leaning or bulging outward (more than 1 inch out of

vertical). Cracks are visible, especially horizontal or stair‑step cracks. Soil is washing out

between blocks or through cracks. The wall’s drainage outlets (weep holes) are clogged or

missing. The top of the wall is uneven. If you ignore these signs, the wall could collapse

suddenly, causing significant soil erosion and potentially damaging nearby foundations.

Montgomery Foundation Repair Co offers retaining wall inspections as part of our foundation

services.

Repair Methods for Retaining Walls

Small cracks in concrete retaining walls can be injected with polyurethane foam, similar to

foundation cracks. Leaning walls can be straightened with helical tieback anchors—steel rods

drilled through the wall and into stable soil behind it, then tensioned to pull the wall back. For

severely damaged walls, we may recommend replacement. In some cases, we install a new

retaining wall in front of the old one (a “buttress” wall). Montgomery Foundation Repair Co

selects the most cost‑effective method that provides long‑term stability.

Preventing Future Retaining Wall Problems

The key to a long‑lasting retaining wall is proper drainage. We install a perforated drain pipe

behind the wall, surrounded by gravel, to carry water away. We ensure weep holes are clear.

We also recommend waterproofing the back of the wall to prevent water from seeping through.

For new walls, we compact backfill in layers to reduce settlement. Montgomery Foundation

Repair Co can retrofit drainage to existing walls at a reasonable cost.
