Case Study: Successful Basement Waterproofing in New York City
A trench 8 feet deep and 14 feet long dug to waterproof the foundation

This case study details the waterproofing project undertaken by Zavza Seal Team for a client experiencing persistent basement leaks in their New York property. The case highlights the importance of a thorough inspection, accurate diagnosis, and efficient execution to address foundation water infiltration issues.

Observations by the Client:

The client reported a recurring problem with moisture and water seepage in their basement. After heavy rain or snowmelt, damp patches would appear on the basement walls, causing concerns about mold growth and structural damage.

Zavza Seal Team Inspection:

Upon receiving the client’s request, a Zavza Seal Team estimator, visited the property to assess the situation. A meticulous inspection revealed the following:

  • Visible water seepage: Damp patches and minor cracks were identified on the basement walls, confirming water ingress from the foundation.
  • Limited window well drainage: The existing window well drainage system appeared inadequate to handle heavy rainfall.

Diagnosis:

Based on the observations, the Zavza Seal Team diagnosed the problem as foundation water leakage. The insufficient window well drainage was likely contributing to the issue by allowing water to accumulate around the foundation walls.

Solution and Implementation:

The Zavza Seal Team proposed a comprehensive waterproofing solution that addressed both the foundation cracks and the window well drainage:

  • Exterior foundation waterproofing: A trench 8 feet deep and 14 feet long was excavated to expose the foundation wall. The Zavza Seal Team then applied a high-quality waterproofing membrane to the exposed foundation, creating a watertight barrier.
  • Crack repair: Identified cracks in the foundation were repaired using appropriate materials to prevent further water infiltration.
  • Window well drain installation: The team installed two new window well drains to improve water collection and prevent pooling around the foundation.
