Client Location: Lindenhurst, NY
Project Type: Crawl Space Foundation Wall Structural Crack Repair
Service Provider: Zavza Seal LLC

Client Concern

A homeowner in Lindenhurst, NY contacted Zavza Seal LLC after noticing a vertical crack in the crawl space foundation wall. The crack, approximately 5 linear feet in length, was a concern both for potential structural weakness and water intrusion. The client wanted a long-lasting repair solution that would address both issues and prevent future damage.

Observation and Diagnosis

Upon inspection, our team confirmed that the crack extended vertically along the crawl space foundation wall. If left unaddressed, the crack could lead to water penetration, compromise the structural stability of the foundation, and potentially worsen over time. Immediate repair was necessary to restore integrity and ensure waterproofing.

Our Solution

To provide a comprehensive and durable repair, Zavza Seal LLC implemented the following process:

1. Surface Preparation
   
   • Steel-brushed the crack to remove all loose and damaged materials, exposing the bare concrete for proper adhesion.
2. Access Port Installation
   
   • Drilled injection access ports every 6 inches using diamond bits to allow for precise material application.
3. Epoxy and Urethane Injection
   
   • Injected a combination of epoxy and urethane formulations into the crack to reinforce structural stability and seal it against water intrusion.
4. First Layer of Waterproofing Cement
   
   • Applied a 6,000 PSI waterproofing cement layer over the injected area to provide a strong, protective surface.
5. Reinforced Fiber Mesh Installation
   
   • Embedded 4.5 oz reinforced fiber mesh into the damp waterproofing cement to add strength and flexibility.
6. Second Layer of Waterproofing Cement
   
   • Applied a second layer of the 6,000 PSI waterproofing cement over the fiber mesh to ensure a secure, watertight seal.
7. Exterior Patching
   
   • Patched the exterior side of the crack above grade for added protection and extended waterproofing two inches onto the floor surface for complete coverage.

Materials and Benefits

The repair used high-quality, industry-approved materials designed for both structural reinforcement and waterproofing. The benefits included:

• Enhanced Structural Integrity: Epoxy and urethane injection bonded the crack, restoring the wall’s strength.
• Effective Waterproofing: Multiple layers of cement and fiber mesh prevented moisture penetration.
• Long-Term Durability: Reinforced repair system designed to withstand environmental stress and soil pressure.
• Improved Property Value: Protecting the foundation prevents costly future damage.

Project Outcome

The vertical crack repair in Lindenhurst, NY was completed successfully, restoring both the strength and waterproofing of the crawl space foundation wall. The homeowner can now rest assured that the foundation is secure, moisture intrusion is prevented, and the structural integrity of the property is protected for years to come.
