Problem

A homeowner in Sagaponack, NY, experienced ongoing issues with their basement foundation walls, including moisture intrusion, mold buildup, and visible efflorescence. These problems threatened not only the structural durability of the foundation but also the air quality inside the home. The property owner contacted Zavza Seal LLC for a long-term, professional solution to strengthen the foundation, waterproof the basement, and eliminate the mold problem.


Solution

Zavza Seal LLC designed a comprehensive repair and waterproofing plan that would address both the current damage and help prevent future moisture-related issues.

  • Surface Preparation: We thoroughly cleaned and steel-brushed the basement foundation walls to remove all dirt, efflorescence, and mold. This step ensured a clean and stable surface for optimal adhesion of repair materials.
  • Crack Repair: All cracks were sealed with Basecrete to restore wall integrity and create a waterproof barrier.
  • Wall and Floor Joint Reinforcement: The joint between the foundation wall and foundation floor was reinforced with 4.5oz fiberglass mesh, extending 4 inches onto the floor for added stability and crack prevention.
  • Concrete Densification: We applied Intercept Densifier to the foundation walls, which penetrates deep into the concrete to strengthen its structure and increase water resistance.
  • Waterproof Coating: Two coats of Basecrete were applied to all floor-to-wall joints, ensuring maximum waterproofing and long-term durability.

Result

The project was completed efficiently, resulting in a basement that is now structurally stronger, fully sealed against water intrusion, and free from mold and efflorescence. The combination of Intercept Densifier and Basecrete provided a robust defense against moisture while improving the overall strength of the concrete walls. The homeowner can now enjoy a healthier indoor environment and the assurance that their basement is protected for years to come.
