Full Perimeter Interior Waterproofing System
The homeowners had dealt with water seeping through the basement walls and floor after every significant rain event for nearly a decade. Previous attempts at DIY fixes — sealant paints, dehumidifiers, and a cheap big-box sump pump — had all failed. The basement had become unusable, with mold growth behind the drywall and a persistent musty odor throughout the house. The clay-heavy soils in Blue Bell were creating hydrostatic pressure that pushed water through every weak point in the foundation.
Carbon Fiber Wall Stabilization & Crack Repair
A beautiful stone-and-block farmhouse in Doylestown had developed a severe horizontal crack across the rear foundation wall, with approximately 2.3 inches of inward bowing. The homeowners first noticed a hairline crack after a heavy spring rain in 2020. By 2024, the crack had widened to over 1/4 inch, water was actively seeping through, and the wall had visibly bowed. The historic nature of the home required a solution that preserved the original stone facade while structurally reinforcing the interior.
Full Crawl Space Encapsulation & Mold Remediation
The homeowners were in the process of selling their Havertown Cape Cod when the buyer's home inspector flagged severe crawl space issues: active mold on floor joists, rotting subfloor in the kitchen area, standing water after rains, and fiberglass insulation saturated and falling down. The sale was at risk. They needed a fast, comprehensive solution that would satisfy the buyer, pass inspection, and protect the home long-term. The post-war construction with minimal original waterproofing made this a challenging but common scenario in Delaware County.
TripleSafe Sump Pump & Exterior Drainage Overhaul
A charming Victorian twin home in downtown West Chester had a stone foundation with a dirt-floor basement that flooded 3-4 times per year. The existing sump pump was a 15-year-old pedestal model that ran constantly but never kept up during storms. The narrow lot (12 feet to the property line) made exterior excavation impossible. The solution required an interior system that could handle high water volume while preserving the historic character of the basement, which the owners used as a wine cellar and workshop.
Exterior Waterproofing Membrane & Drainage System
A split-level home in Yardley, just blocks from the Delaware River, had chronic water intrusion through the below-grade walls of the lower level. The high water table in this river-adjacent area meant hydrostatic pressure was constant, not just during storms. The homeowners had tried interior sealants twice, but water always found new paths. With the lower level used as a home office and guest suite, the moisture was destroying drywall, carpet, and electronics. An exterior solution was the only permanent fix.
New Construction Basement Waterproofing Correction
A newly built colonial in a King of Prussia development was showing water seepage through the basement walls just two years after construction. The builder-grade waterproofing — a thin spray-on membrane and a single sump pump — had failed. The clay-heavy soils typical of the area were creating hydrostatic pressure that overwhelmed the minimal system. With the home still under the builder's warranty, the homeowners initially tried to get the builder to fix it, but after 8 months of delays, they hired Platinum for a proper permanent solution.
