Retaining walls

Built to hold the hill, and drain it

From
How long
One to two weeks for most walls

A retaining wall holds back soil, and soil full of water is heavy. That’s why most walls fail: not the stone, but what’s behind it. Every wall we build starts with a footing on undisturbed ground, has drain rock and a perforated pipe behind the first course, and is backfilled in lifts, compacted as it goes.

Taller walls get geogrid laid into the backfill to tie the soil to the wall, and an engineer’s plan. We build in segmental block or in natural limestone from the quarry up the road.

Questions

Why did my old wall lean?

Almost always water: no drain behind it, so the soil got heavy and pushed. Ours are built to drain.

Do I need a permit?

Walls over four feet usually need an engineer's plan and a permit; we handle both.
