Retaining walls

Strength behind the stone

A retaining wall does real structural work, so what you can't see matters most. We excavate a solid footing, build with the right block or stone, and add drainage stone and geotextile behind the wall so water pressure can't push it out of place over the years.

Wall anatomy

The wall has to fight pressure you never see

A retaining wall is only partly about the face stone. The footing, drainage stone, geotextile and backfill are what keep it straight through freeze-thaw cycles.

Why Excavation Frenna

Walls that stay put

Solid footing

We excavate and compact a proper base course so the wall has a stable, level foundation to build on.

Drainage built in

Drainage stone and geotextile relieve water pressure — the main reason walls lean and fail.
