Retaining Wall Design in Newtown Square, PA

Newtown Square and Edgmont Township's rolling topography creates retaining wall requirements on a significant portion of the properties we design. Some walls are purely functional — holding a grade change to create a flat usable area. The best walls are both functional and aesthetic — designed as landscape architecture, not just engineering.

When You Need a Retaining Wall

Signs your Newtown Square property needs a retaining wall:

• Sloped backyard that limits usable outdoor space
• Erosion on a hillside or slope
• Grade change between your property and adjacent properties
• Existing wall that's leaning, bowing, or showing drainage failures
• New patio design that requires grade modification

Wall Engineering for Main Line Properties

The engineering requirements for a Newtown Square retaining wall depend on:

• Wall height: walls over 4 feet typically require geogrid reinforcement and may require structural engineering review
• Soil type: Delaware County and Chester County soils vary — we assess before we design
• Drainage: water management behind the wall determines whether it lasts or fails
• Load: walls near structures, driveways, or with vehicle loads above them need additional design consideration

Material Selection

EP Henry or Allan Block Segmental Wall Block The most common and cost-effective choice. Available in multiple colors and textures. ICPI/NCMA installation standards well-established.

Chester County Fieldstone For properties where natural stone character is required. Dry-laid or mortared depending on height and structural requirements.

Boulders For naturalistic grade transitions on larger lots — a boulder wall feels organic and appropriate in landscape settings where the engineered look would feel wrong.
