Problem:
A residential property in Brooklyn, NY was experiencing recurring water intrusion at a utility wall where electrical and plumbing conduits penetrated the masonry. During heavy rain events, moisture was entering through small cracks and voids around the electrical and plumbing penetrations. Over time, this posed a risk to the electrical components, interior finishes, and the overall integrity of the wall.
The homeowner contacted Zavza Seal after noticing dampness, minor staining, and concern about potential long term damage. Our inspection confirmed that the conduit penetrations were not fully sealed and that previous patching attempts lacked proper bonding and waterproofing protection.
Solution:
Zavza Seal implemented a comprehensive utility wall waterproofing and structural sealing solution designed to permanently stop water intrusion and reinforce the surrounding masonry.
Scope of Work:
- Surface preparation by thoroughly cleaning the masonry and removing loose debris, laitance, and contaminants
- Mechanical abrasion of the affected areas to ensure proper bonding of all repair materials
- Drilling and installing injection ports around the perimeter of the electrical and plumbing penetrations
- Structural epoxy injection to seal internal voids and cracks associated with the conduit penetrations
- Polyurethane and epoxy injections to expand within hidden gaps and create a watertight seal
- Removal of injection ports followed by filling all holes with high strength mortar
- Application of a waterproofing cement base coat over the repaired areas
- Embedding 4.5 oz fiberglass reinforcing mesh into the base coat for added strength and crack resistance
- Application of a second coat of waterproofing cement to fully encapsulate and seal the repair
- Repeating the same waterproofing process on the adjacent electrical wall penetration
- Protection of all nearby finishes and full cleanup of construction debris upon completion
Results:
Once the work was completed, the utility wall was fully sealed and reinforced against future water intrusion. The conduit penetrations are now protected by a multi layer waterproofing system that addresses both surface and internal vulnerabilities. The homeowner gained peace of mind knowing their electrical and plumbing areas are secure, dry, and structurally sound.
This Brooklyn waterproofing project highlights Zavza Seal’s expertise in utility wall waterproofing, structural sealing, and long term water intrusion prevention for residential properties in New York.
Why This Matters?
Properly sealing utility wall penetrations is critical for preventing moisture damage, electrical hazards, and structural deterioration. Professional injection waterproofing combined with cementitious reinforcement provides a durable solution that outperforms temporary surface patches.
