Retaining Wall Construction Philadelphia

Smart Retaining Wall Construction for Philly Homes & Businesses

No gimmicks, no guesswork—just the right wall for your property. Call APS for retaining wall solutions that actually match the job.

• Gravity Walls – Built to Settle In, Not Shift Out

  A gravity wall relies on its own mass. Concrete blocks, stacked right and set deep, form a barrier that holds the line against pressure. These are the go-to on smaller urban lots where there’s no room for overbuilt systems. For backyard landscapes, raised beds, or patio borders, this is the wall that blends in and stays solid.

• Cantilevered Systems – Reinforced and Ready for Load

  When a wall has to fight pressure long-term—steep grades, heavier soil, deeper digs—we move to reinforced builds. Cantilevered walls use steel, poured footings, and tie backs to hold position. We calculate pressure, build to spec, and lock the wall in behind the scenes so the finished face looks clean and holds steady. This is infrastructure-grade work applied at the residential and small commercial level.

• Segmental Walls – Flexible Design with Real Strength

  Segmental systems are made up of interlocking units that flex with ground movement and water flow. They're ideal for patios, curves, and landscape transitions where a rigid wall would crack over time. When matched with proper drainage and solid prep, they look sharp and hold up—less mass, more engineering.

• Bluestone: The Perfect Balance of Strength and Style

  Bluestone isn’t just tough—it’s got that natural, understated elegance that fits right into Philly’s mix of historic charm and modern style. You’ll see it on classic brownstone steps, tucked into garden walkways, or framing cozy backyard patios. It holds up against the city’s rough winters, resists wear, and looks better with age.

FAQs for Retaining Walls in Philadelphia

• Do I need a permit for a retaining wall project in the city?

  If your wall is over 30 inches tall, you’re required to pull permits through Philadelphia’s Department of Licenses and Inspections. Skipping that step isn’t worth it—it can mean fines, delays, or tearing down finished work. APS handles the paperwork, inspection coordination, and makes sure every build is backed by a valid license and fully compliant with city code.

• What does retaining wall construction in Philadelphia typically involve?

  Every site is different, but the process usually includes layout and grading, excavation, base installation, drainage systems, and then block or stone placement. Retaining wall construction in Philadelphia also means managing tight lots, old infrastructure, and varied soil conditions—all things we’ve seen and solved before.

• How do I choose between wall contractors?

  Start by looking at the basics: experience, references, permits pulled under their name. Then dig deeper. Do they explain their process clearly? Do they understand local terrain? Do they actually show up when they say they will? Good wall contractors don’t guess on material quantities or skip drainage—if the estimate seems rushed, so will the job.

• Can APS repair or replace an existing wall, or do you only build new?

  We do both. We’ve rebuilt collapsed walls that were only a few years old and reinforced walls that just needed smarter drainage and stronger footing. If your wall is leaning, cracking, or holding water, we’ll inspect it, give you honest recommendations, and let you know if a repair is viable or if it’s time to replace.

• How long will a properly built retaining wall last?

  With quality materials, proper base prep, and professional installation, a retaining wall should last decades—some over 50 years without issue. We don’t aim for “long enough.” We build for the next generation to not have to think about it.
