Client Observation

A homeowner in Freeport, NY, contacted Zavza Seal LLC after noticing severe water damage in basement, Freeport, NY. The issue was particularly noticeable during and after heavy rains when water would seep into the basement through the block foundation wall near the Bilco door opening. The homeowner expressed concerns about potential structural damage and the possibility of mold growth due to the recurring water intrusion. The client also mentioned that previous attempts to mitigate the problem with DIY solutions had failed.

Diagnosis by Zavza Seal LLC

Upon inspection, the Zavza Seal team identified that the water was infiltrating through cracks in the foundation wall and the concrete floor. The problem was exacerbated by inadequate exterior basement waterproofing Freeport, NY and drainage systems, leading to repeated water intrusion after every heavy rain. The water leaking into basement after heavy rain from the Bilco door area was contributing to pooling and dampness in the basement, making the space unusable.

Our thorough assessment revealed that the block foundation wall and the surrounding area adjacent to the Bilco door opening were the primary sources of the leak. Without addressing the underlying causes—waterproofing deficiencies and crack repairs—the problem would likely persist, leading to increased water damage in basement Freeport, NY over time.

Proposed Solution

The team at Zavza Seal LLC developed a comprehensive plan to resolve the water damage in the basement and prevent future occurrences. The key steps included:

  1. Excavation and Waterproofing:
    • We proposed excavating the full length of the house’s foundation wall—35 feet long by 5 feet deep—extending to the corner return near the Bilco door opening, which would involve an additional 5 feet of excavation.
    • After excavation, the foundation wall would be thoroughly cleaned to remove any debris and contaminants, ensuring a smooth surface for basement waterproofing Freeport, NY.
  2. Liquid Waterproof Membrane:
    • A high-performance liquid waterproof membrane was applied to the entire subgrade section of the wall. This membrane provides a durable, waterproof barrier that prevents future water infiltration through the foundation.
    • All cracks in the cement plaster, both above and below grade, were carefully repaired to ensure no weak spots in the structure.
  3. Protection Mat and Backfill:
    • To further protect the newly waterproofed wall, we installed a protection mat over the liquid membrane. This mat acts as an additional layer of defense, ensuring that the membrane remains intact and continues to perform effectively.
    • The excavated area was then backfilled to the original grade level, restoring the landscaping around the foundation while maintaining proper drainage.
  4. Masonry Coating:
    • For added aesthetic appeal and protection, we applied an exterior masonry coating to the above-grade section of the foundation wall. The homeowner had the option to choose their preferred color, allowing the repairs to blend seamlessly with the existing structure.
  5. Sump Pump Installation:
    • To further mitigate the risk of water accumulation in the basement, we installed a new sump pump connected to the existing discharge pipe. This pump is designed to actively remove water from the basement, preventing any future flooding or water pooling issues.
    • The sump pump installation Freeport, NY was completed with a reliable, high-capacity model that would ensure optimal performance even during heavy rainstorms.

Implementation of the Solution

Once the client approved the proposal, our team quickly mobilized to begin work. The first step involved careful excavation along the foundation wall and the Bilco door area. Our team worked efficiently to minimize disruption to the homeowner’s property while ensuring the excavation was thorough and precise.

Next, we applied the liquid waterproof membrane to the cleaned foundation wall, followed by the installation of the protection mat. This process provided a robust waterproofing system that would effectively block water from penetrating the basement.

Once the excavation and waterproofing steps were complete, the team installed the sump pump, ensuring that any water that might collect in the future would be efficiently removed from the basement. Finally, the above-grade section of the wall was coated with the masonry finish, completing the project.
