Rear Patio and Steps Rebuild - Wayne Colonial
Project Overview
A Wayne homeowner had been living with a crumbling rear concrete patio for years. The original slab had heaved, cracked, and settled unevenly due to decades of freeze-thaw cycling and inadequate base preparation. One step had a broken nose presenting a trip hazard. The iron railing had rusted through at two base post anchors. Water pooled against the house foundation after every rain due to negative slope. Exterior Solutions LLC demolished the existing concrete patio and steps, excavated and installed a proper compacted base system, and rebuilt the entire outdoor space using a tumbled concrete paver system with new bluestone steps, a black aluminum railing, and proper positive drainage away from the foundation.
Analysis
Full demo revealed the original pour had been placed directly on uncompacted soil with no gravel base and no reinforcement. The soil beneath had settled and shifted over decades, leaving unsupported spans that had fractured under load. Excavation depth was 10 inches below finished grade to accommodate a 6-inch compacted processed stone base and a 1-inch sand setting bed. We found the original steps had been tied to the patio slab with rebar pins that had corroded and expanded, further cracking both sections. The foundation wall behind the patio showed minor efflorescence from the water pooling. We applied a waterproofing masonry coating to the exposed foundation section before backfilling.
Process
Day one: concrete demolition completed with skid steer, debris loaded to roll-off. Excavation to 10 inches, soft spots identified, filled and compacted. Day two: gravel base in two lifts, each compacted with reversible plate compactor, slope verified by laser. Sand setting bed screeded. Day three: paver installation began at the house and worked outward — soldier border course first, then field pavers in running bond. Cut work at edges and around step opening with wet diamond saw. Paver surface compacted over rubber mat. Polymeric sand swept, compacted, activated. Day four: step and railing post footings poured. Day six (after curing): bluestone treads mortared and pointed, railing system assembled and secured. Day seven: final inspection, cleanup, and mortar joint sealing.
Outcome
The patio now sheds water cleanly away from the foundation, resolving the pooling problem that had worried the homeowner about basement intrusion for three summers. The tumbled paver surface provides a natural, timeless aesthetic that complements the colonial architecture of the home. The bluestone steps with black railing give the rear entry a polished, finished look. The new railing meets current code height requirements and provides solid fall protection where none existed before. Polymeric sand joints are clean and weed-resistant. The homeowner added outdoor furniture and uses the space daily through warm-weather months, describing it as the best-looking part of the property.
Project Details
Materials Used
Demolition: concrete saw, jackhammer, skid steer loader for debris removal. Base: 6 inches of NJ DOT-spec processed gravel compacted in 2-inch lifts, laser-verified slope 1/8 inch per foot away from foundation. Setting bed: 1-inch coarse washed concrete sand screeded to slope. Pavers: Unilock Umbriano 12x12 and 12x18 tumbled concrete pavers, graphite with natural blend, soldier course border in tan. Polymeric sand: Techniseal HP Pro+ activated with water compaction. Steps: 2-inch full-color bluestone treads, natural cleft finish, mortar bed over concrete footing. Railing: 42-inch black powder-coated aluminum with 1/2-inch square balusters, posts in concrete footings. Foundation treatment: Drylok Extreme applied to exposed block wall prior to backfill.
Methods & Techniques
