What the work covers
- Segmental retaining walls
- Terracing and level changes
- Drainage behind the wall
- Steps and grade transitions
Segmental wall systems are already modular. The engineering that matters — batter, base, reinforcement, and drainage — is where the discipline goes, not the block itself.
Common questions.
When does a wall need engineering?
Height is the usual trigger, and thresholds vary by municipality. Surcharge above the wall — a driveway, a slope, a structure — can require it at a lower height.
Why do retaining walls fail?
Almost always water. A wall without drainage behind it is holding back saturated soil, which weighs far more than the design assumed — and in this climate that backfill then freezes and expands against the wall every winter.
