Case Study: Comprehensive Basement Foundation Wall Repair in Deer Park, NY

• Project Location: Deer Park, NY
• Service Provided: Basement Foundation Wall Waterproofing

Client Challenge

The homeowner in Deer Park, NY, faced a recurring water intrusion issue in their basement. Water was seeping through the basement foundation wall, which posed a risk of structural damage and mold growth . The homeowner reached out to Zavza Seal LLC to prevent further damage, eliminate moisture issues, and ensure a dry, stable basement environment for their basement foundation wall repair deer park.

Project Scope and Proposal

For this 36 linear feet (LF) section of the basement foundation wall, Zavza Seal LLC proposed a comprehensive waterproofing and crack repair solution, including excavation, cleaning, crack repair, and waterproofing. The primary steps included:

• Excavation: Excavating along the basement wall’s exterior—covering 27 LF along the main wall and 9 LF along the corner return—to reach down to the footing.
• Surface Preparation: Cleaning the wall thoroughly to assess and repair any cracks, defects, or areas of weakness along the entire 36 LF length.
• Waterproofing: Applying a liquid waterproofing membrane across the wall surface, followed by a protective mat to ensure durability and prevent future water infiltration.
• Backfilling and Grading: Backfilling the excavated area to the original grade, adding 2 cubic yards (CY) of soil to form a graded slope away from the foundation wall, further directing water away from the home.

Implementation Process

The Zavza Seal team completed each step with precision, ensuring the foundation wall was sealed and protected for long-term resilience against water intrusion.

1. Excavation

Our team carefully excavated down to the footing along the 36 LF wall length, allowing access to the entire foundation wall for thorough inspection and preparation. The excavation covered both the main wall section (27 LF) and corner return (9 LF), exposing any potential weaknesses contributing to water infiltration.

2. Cleaning and Repair

Once excavated, our technicians cleaned the exposed wall to remove dirt, debris, and any damaged areas on the concrete surface. This thorough cleaning allowed us to detect cracks and other structural defects. Each defect was repaired to ensure a smooth, even surface for optimal membrane application.

3. Waterproofing Application

To protect the basement wall from future water intrusion, we applied a liquid waterproofing membrane over the entire 36 LF surface. This membrane acts as a barrier, preventing moisture from entering the foundation. We also added a protection mat on top of the membrane, shielding it from external forces, soil pressure, and potential damage over time.

4. Backfilling and Grading

After the waterproofing was complete, our team carefully backfilled the excavated area to match the original grade, adding approximately 2 CY of soil to form a slope away from the foundation. This added grading helps divert rainwater and groundwater away from the foundation, further minimizing the risk of water infiltration.

The basement foundation wall in dire condition before the Zavza Seal Team can to work on it.

Project Outcome

The completed project delivered a fully waterproofed basement foundation wall with strengthened crack repairs and a strategic slope to divert water away. The homeowner was highly satisfied, reporting immediate improvements with no signs of water seepage even after heavy rain. This repair not only resolved the immediate water intrusion issue but also fortified the home’s foundation against future moisture damage, reducing risks of mold and structural deterioration.
