Problem
The owner of Apartment #4 in a Brooklyn residential building reported persistent water intrusion along the north side of the unit. The water damage was affecting both the interior walls and the concrete foundation, raising concerns about long-term structural integrity and interior finishes. Based on a detailed inspection by our Senior Estimator, it was determined that both the exterior and interior areas of the foundation required waterproofing to ensure a long-lasting solution. Full excavation around the exterior was deemed unnecessary, which helped keep the project cost-efficient.
Solution
Zavza Seal LLC implemented a dual-scope waterproofing strategy targeting both the exterior and interior perimeters of the affected area.
Exterior Perimeter Waterproofing (Approx. 20 Feet along the North Side)
- Ground the surface with diamond blades to remove loose and damaged material, exposing the bare concrete for optimal adhesion.
- Applied high-performance waterproofing cement, waterproofing adhesives, caulking, and 4.5oz reinforced fibermesh to seal and strengthen the exterior surface.
- Used additional materials as needed, based on real-time site assessment by our foreman, to ensure maximum durability and water resistance.
Interior Perimeter Waterproofing (Approx. 18 Feet along the North Side)
- Removed the bottom 2 feet of drywall along the affected area.
- Cut and removed sections of the floor, floor plate framing, and wall stud framing where necessary to access the foundation wall.
- Ground the surface with diamond blades to remove any loose or damaged concrete.
- Applied the same high-performance waterproofing cement, adhesives, caulking, and 4.5oz reinforced fibermesh as used on the exterior.
- Restored all removed sections, including patching, taping, sanding, and painting. Efforts were made to match existing paint and flooring with the help of the apartment owner.
Result
The combination of interior and exterior waterproofing completely resolved the water intrusion issue for Apartment #4. The high-end materials and reinforced application method not only sealed the foundation against future leaks but also improved the overall strength and durability of the structure. The restored walls and floors blended seamlessly with the existing finishes, leaving the apartment in pristine condition.
