How we build it

A retaining wall fails for one of two reasons: no drainage behind it, or no base under it. We build a compacted footing below frost depth, backfill with clean crushed stone, and run drainage so water leaves the wall instead of pushing on it.

Above that, the face is what you actually see — fieldstone fitted by hand, granite block set to a string line, or segmental units stepped back for batter. Steps get the same treatment: bluestone treads and granite risers, set level and pinned so they do not rock.

What's included

  • Excavation and compacted footing below frost depth
  • Clean crushed-stone backfill with drainage
  • Geotextile separation where soils are fine
  • Battered or vertical face, depending on height and material
  • Cap course set and adhered
  • Bluestone treads and granite risers for steps
  • Landings set level and pitched to shed water
  • Grading and loam restoration behind the wall

Materials we work in

  • Fieldstone and boulder, fitted dry
  • Granite block — new and reclaimed
  • Segmental retaining-wall units with caps
  • Poured and block foundation walls
  • Bluestone treads, 2" and thicker
  • Granite risers, curbing and slabs
