Why Wilmington Homeowners Choose Keystone for Retaining Walls

Wilmington properties: Older row, twin and Victorian homes plus close-in suburbs; owners want hardscape that maximizes compact urban yards.
Building Retaining Walls in Wilmington: What the Site Demands
Our sloped, clay-backed lots put real lateral load behind a wall. Built without drainage and proper bearing, that clay swells when wet and pushes walls out of plumb.
In Wilmington: Tight city and inner-suburb lots with limited access; row and twin homes share grade lines with neighbors.
We set walls on a compacted leveling pad, backfill with free-draining stone and a drain tile, and add geogrid reinforcement on taller runs so the hillside stays put.
Permitting: City of Wilmington (or New Castle County for the suburbs) permitting — city projects mean stricter access, right-of-way and stormwater rules.
Retaining Walls considerations for Wilmington lots
- Drainage stone + perforated drain tile behind every wall to relieve clay water pressure
- Geogrid soil reinforcement on taller or surcharged walls
- Walls over 4 ft typically need an engineered design and a township permit
