A retaining wall holds back soil and water — and above a certain height, New Jersey requires it to be engineered. We design segmental block, poured concrete and timber walls for the soil, surcharge and drainage at your site, and seal the drawings for your town.
In New Jersey, retaining walls above a set height (often 4 feet, measured bottom of footing to top) require sealed engineering. We design the wall for the retained soil, any surcharge (a driveway or structure above), drainage and frost.
Most municipalities require sealed engineering once a wall passes about 4 feet in height, or any height when it supports a surcharge like a driveway, pool or structure. Tiered walls and walls near property lines usually need it too.
Retained soil pressure, surcharge loads, water and drainage behind the wall, and frost at the base. Poor drainage is the most common cause of retaining-wall failure, so we design the drainage as carefully as the wall itself.

Yes — segmental retaining walls, poured concrete, and timber. We size the wall and the drainage for your soil and site.
We evaluate failing walls and provide a sealed repair or replacement design.
