Our Retaining Wall Installation Process

01

Site Assessment & Design

We evaluate the slope, soil conditions, drainage, and proposed wall height to design a properly engineered wall.

02

Permitting

Permits are required for walls over 4 feet in most jurisdictions. We pull permits and submit engineering plans where needed.

03

Excavation & Foundation

Base trench is excavated to the proper depth and width. A compacted gravel base is installed for footing.

04

Wall Construction & Drainage

Wall units are installed in interlocking courses, geogrid is added for tall walls, and gravel backfill with drain pipe prevents water buildup.

Retaining Wall Installation FAQ for Wilmington Homeowners

How often should Wilmington homeowners get retaining wall installation?
Given Wilmington's cold winters averaging 32°f with 21 inches of snowfall, most homeowners benefit from retaining wall installation at least once a year. Freeze-thaw brick and mortar damage (Dec–March) often makes spring or fall the optimal time to schedule service.
What home types in Wilmington most need retaining wall installation?
Historic brick row houses in downtown Wilmington and Colonial and Cape Cod homes throughout New Castle County are the most common home types in Wilmington and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Do retaining walls need drainage?
Yes — drainage behind retaining walls is critical. Without it, hydrostatic pressure from saturated soil and freeze-thaw cycles are the primary cause of wall failure. A gravel backfill zone and perforated drain pipe should be included.
What material makes the best retaining wall?
Segmental retaining wall block (like Allan Block) is the most popular — durable, easy to maintain, and comes in many styles. Natural stone is beautiful but more expensive. Timber is lowest cost but has a 15–20 year lifespan.
How tall can a retaining wall be without a permit?
Most jurisdictions allow walls up to 3–4 feet without a permit. Taller walls require engineering and permits to ensure structural safety.
Can I build a retaining wall myself?
Small walls under 3 feet using segmental block are manageable DIY projects. Taller walls — especially those retaining significant soil loads — require professional engineering and installation to prevent failure.
