Structural Retaining Walls

Walls that hold a hillside

and look like they grew there.

Engineered, drained, and faced to read as natural stone outcroppings, not as infrastructure.

Hardscape ยท Engineered Walls

Geogrid, drainage,
and the long view.

As a core part of our Hardscape Design & Construction practice, this discipline is where the craft becomes specific โ€” the techniques, materials, and tolerances that separate generational work from passable work.

A retaining wall is a structural element first and a landscape feature second. Forget either responsibility and the project fails โ€” sometimes spectacularly.

Our retaining walls are engineered to current IBC standards, drained to prevent hydrostatic failure, and faced in stone or board-formed concrete chosen to fit the architecture.

Anything over four feet gets stamped engineering. Below that, we still build to engineered standards: geogrid reinforcement, perforated drain at the base, gravel backfill, and proper batter.

The Craft

01

Engineered geogrid

Tied back into the slope every 16โ€“24" of lift.

02

Drain rock & weep

Perforated pipe and gravel chimney prevent water build-up.

03

Stone or board-form face

Architectural finish over engineered structure.

Materials & Spec

The short list we trust.

Allan Block & Versa-Lok Segmental retaining systems
Boulder retaining 1โ€“4 ton hand-set boulders
Mirafi geogrid Soil reinforcement
4" perforated drain Wrapped in filter fabric

The Process

Four steps. A clear vision.

01

Geotech & engineering

Soils review and stamped drawings where needed.

02

Excavate & footing

Cut bench, set leveling pad, place drain.

03

Build with geogrid

Course-by-course with reinforcement layers.

04

Cap & backfill

Capstone set, gravel chimney, topsoil restored.

Considerations

Questions worth asking.

California requires stamped engineering for any retaining wall over 4 feet from footing to top โ€” and we recommend it on any wall holding a structure or driveway.

Not if it's built with geogrid and proper drainage. We've inspected our 25-year-old walls โ€” still plumb.
