Engineered Retaining Walls in Waltham, MA

A retaining wall contractor that knows Waltham

Waltham sits in Greater Boston (Middlesex County), and projects here near Charles River and Brandeis University need to handle a specific blend of weather and soil. Brandeis area and Waverly Oaks feature mature stonework. We've built retaining walls throughout South Side, Waltham Center, and the rest of town with that local knowledge baked in.

JL Masonry has been serving Waltham homeowners for over 15 years. Our crews understand the victorian aesthetic that dominates South Side, and we stock material samples that match Waltham's historic vocabulary.

Retaining Wall questions, answered

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.
