Client: Residential Homeowner
Location: Basement Foundation Wall (Approx. 7 Linear Feet)
Service Provided by: Zavza Seal LLC

Client’s Observation

The homeowner noticed a persistent water intrusion issue in the basement. During heavy rain, water would seep through a structural crack in the corner of the basement foundation wall, near the window. This caused dampness in the basement and raised concerns about potential structural and moisture-related damage. The homeowner attempted temporary repairs with patching material, but water continued to infiltrate.

Diagnosis by Zavza Seal LLC

Upon inspection, the Zavza Seal team identified that the water intrusion was due to a structural crack extending along the basement foundation wall, running approximately 7 feet vertically. The team observed that prior patching attempts failed to address the underlying issue, allowing water to penetrate the crack. Further examination revealed that the crack required stabilization, sealing, and waterproofing to prevent future water entry and to strengthen the foundation wall.

Solution Implemented

To address the root cause of the water intrusion and provide a lasting repair, the Zavza Seal team devised a comprehensive approach:

1. Removal of Existing Patching Material
   1. The team began by grinding off all existing patching material along the crack, exposing the bare concrete surface. This step was essential to ensure that new materials could bond effectively to the concrete and provide a robust repair.
2. Preparation of the Crack for Injection
   1. The entire length of the crack was carefully cut, and the team drilled injection ports at 6-inch intervals from the top to the bottom. These ports were designed to facilitate uniform distribution of repair materials within the crack, enhancing its stabilization.
3. Injection of Urethane and Epoxy Formulations
   1. The team utilized a combination of urethane and epoxy formulations to fill the crack completely. Urethane was used for its flexibility and waterproofing properties, ensuring that the crack was fully sealed against water infiltration. Epoxy was injected for its strength and bonding capacity, helping to stabilize the foundation wall.
4. Application of Basecrete Waterproof Cement
   1. Once the injection was complete, the Zavza Seal team reinforced the area with a mesh strip and applied a layer of Basecrete waterproof cement over the crack. Basecrete provided an additional waterproof barrier and strengthened the repaired area, protecting it from future wear and environmental exposure.

Results and Client Satisfaction

The comprehensive repair by Zavza Seal LLC effectively stopped water infiltration and restored the integrity of the basement foundation wall. The client was pleased with the thoroughness of the repair process and the professionalism of the Zavza Seal team. Since the repair, the basement has remained dry, even during heavy rain, and the client now has peace of mind knowing the foundation is reinforced and waterproofed for long-term durability.
