How tall can a retaining wall be?

We build walls from 2 feet (garden walls) up to 12+ feet (engineered terraces). Walls over 4 feet require an engineer's stamp and permit.

What's the most important part of a retaining wall?

What you can't see — drainage. A wall without proper perforated drain tile, crushed-stone backfill, and geotextile separator will fail within 5–10 years no matter how good the face stone looks.

Can you build into a slope or only against existing soil?

Both. We can cut into a hillside for a benched terrace or build a freestanding wall to create a level yard above grade. Each requires different drainage and structural approach.

Retaining Wall in Medford, MA

A retaining wall contractor that knows Medford

When we take on a retaining wall project in Medford, the first thing we factor in is the local soil: urban with clay; mystic river alluvial in lowlands. Combined with river fog impacts north-facing masonry, this dictates how we engineer the base and joints. The result is a retaining wall that performs the way it's supposed to — for decades.

Choosing a retaining wall contractor in Medford means choosing someone who'll show up. We do. Licensed, insured, MA HIC registered — and the same crew you meet at the estimate is the crew that builds the project.
