Overview
A homeowner in Westbury, NY contacted Zavza Seal LLC after discovering signs of water intrusion in their cinder block crawlspace. Water infiltration in crawlspaces can lead to structural damage, mold growth, and indoor air quality issues. To prevent these long-term risks, the client opted for professional crawlspace waterproofing.
Problem Assessment
Upon inspection, our team identified that the **crawlspace wall surface—approximately 132 square feet—**was suffering from water seepage through the porous cinder blocks. The issue was likely due to hydrostatic pressure from the surrounding soil and insufficient prior sealing.
Scope of Work
Zavza Seal LLC executed a multi-step, high-performance waterproofing solution tailored for durability and long-term moisture protection.
Our Crawlspace Waterproofing Process Included:
- Cleaning and Scarification:
The cinder block walls were first cleaned and scarified to ensure optimal adhesion of the waterproofing material. This surface preparation step is crucial for a strong, lasting seal. - High-Strength Waterproofing Cement at Wall Joint:
We applied a layer of 6,000 PSI waterproofing cement at the wall-to-floor joint—an area highly susceptible to water intrusion. - Installation of Fiberglass Mesh Reinforcement:
A 4.5 oz fiberglass mesh strip was embedded, extending 6 inches up the crawlspace wall and 6 inches across the concrete slab. This mesh helps reinforce the waterproofing membrane and adds resistance to cracking and shifting. - Second Waterproofing Cement Coat:
A second coat of waterproofing cement was applied to fully encapsulate the fiberglass mesh, sealing all potential penetration points. - Extended Wall Protection:
The final waterproofing layer was extended 3 feet up the interior crawlspace wall to protect against higher-level water intrusion and capillary action through the masonry.
