Building Retaining Walls in Avondale: 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 Avondale: Flat-to-gentle borough parcels with high-water-table pockets near the creek.
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: Avondale Borough / New Garden Township zoning, with floodplain and Conservation District review near the White Clay.
Retaining Walls considerations for Avondale 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
