Problem
The homeowner in Bellmore, NY, noticed persistent water intrusion in their basement, especially during heavy rain. Water stains and dampness on the basement wall raised concerns about the structural integrity and the indoor air quality of the property. Upon inspection, our Zavza Seal team identified a vertical crack along approximately 5 linear feet of the basement foundation wall, as well as water penetration through a plastic conduit passing through the wall.
Solution
Zavza Seal LLC developed a targeted solution to stop the water intrusion and restore the basement’s structural soundness. Our comprehensive process included the following steps:
- Surface Preparation: We scarified the surface of the crack area to eliminate all previous patching materials and any loose or foreign debris, ensuring proper adhesion and penetration of repair materials.
- Crack Injection: Every 16 inches along the length of the crack, we drilled precise holes for the resin injection. This resin was injected to fully penetrate, seal, and stabilize the foundation crack, providing both structural reinforcement and waterproofing.
- Waterproof Coating: After the resin cured, we applied mesh-reinforced Basecrete waterproof cement across the entire repair surface. This product added a durable, water-resistant layer that would hold up against future moisture intrusion.
- Thru-Wall Conduit Repair: On the exterior side of the foundation wall, we excavated the area around the plastic thru-wall conduit. We thoroughly cleaned out the joint cavity, applied hydraulic cement for initial sealing, and finished with a waterproofing cement coating for long-term moisture protection.
Result
The waterproofing repair successfully stopped all water intrusion in the affected section of the basement. The combination of high-performance crack injection, Basecrete application, and exterior joint sealing ensured a robust and long-lasting solution. The homeowner now enjoys a dry, stable basement and peace of mind knowing their foundation is protected.
