Failures usually come from drainage pressure, weak or wet soils, poor base prep, or landscaping walls built too tall without reinforcement.

Yes, if the structure is still salvageable. We inspect movement and soils first, then recommend anchors, reinforcement, drainage fixes, or rebuild.

For steep or tall walls we use reinforced earth (MSE/geogrid), big-block systems, or geo-anchors depending on height and site conditions.

We install a full clean-stone drainage zone with perforated pipe and outlets per design—water control is the #1 factor in wall life.
