Building Retaining Walls in Malvern: 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 Malvern: Rolling Main Line-edge terrain with upscale graded lots; clean grades that suit crisp, formal layouts.
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: Malvern Borough / Willistown & East Whiteland Township zoning, with standard grading and stormwater review.
Retaining Walls considerations for Malvern 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
