Problem:
A homeowner in Huntington, NY contacted Zavza Seal after noticing moisture intrusion and deterioration along the bottom four feet of two exterior foundation walls. One wall measured approximately seven linear feet and the second measured approximately six linear feet. The existing drywall showed signs of damage, and continued exposure to moisture risked mold growth, insulation failure, and long term structural concerns. The homeowner needed a permanent waterproofing solution paired with a proper wall rebuild.
Solution:
Zavza Seal developed a step by step approach to fully waterproof and restore the affected exterior walls while improving insulation and interior finishes.
Our team completed the work as follows:
- Removed the existing drywall to expose the foundation walls.
- Thoroughly cleaned the foundation surface to ensure proper bonding.
- Applied a high strength 6,000 PSI waterproofing cement to fully seal and waterproof the bottom four feet of both exterior walls.
- Reconstructed both walls using pressure treated bottom and top framing plates for moisture resistance.
- Installed new 2×4 wall studs to rebuild the wall structure.
- Installed R13 fiberglass insulation across the entire subject area to improve thermal performance.
- Installed new drywall, tape, and compound.
- Returned to sand and paint, delivering a clean and finished appearance.
This method ensured that moisture was addressed at the foundation level before rebuilding the interior wall system.
Results:
The completed project delivered fully waterproofed foundation walls, improved insulation, and a restored interior finish. The homeowner now has stronger protection against water intrusion, improved energy efficiency, and peace of mind knowing the walls were rebuilt correctly from the foundation outward.
Homes in Huntington often face groundwater pressure and seasonal moisture fluctuations. Proper foundation waterproofing combined with pressure treated framing and insulation is essential to prevent recurring damage and protect interior living spaces.
