Basement Water Intrusion Repair and Waterproofing
The Problem
A homeowner in Seaford, NY contacted Zavza Seal after discovering water intrusion in their basement bedroom closet, spanning approximately 4 linear feet, with an additional 1 foot of affected area behind the drywall. This kind of water penetration is common in older foundations where joints between the wall and floor begin to break down over time.
The homeowner reported dampness and minor discoloration along the closet wall, indicating moisture seepage through the joint between the foundation wall and slab. If left untreated, this could lead to mold growth, structural degradation, and deterioration of the finished interior.
Our Solution: Targeted Joint Waterproofing with Reinforced Cement System
To effectively resolve the issue, Zavza Seal implemented a targeted waterproofing strategy using a reinforced Basecrete cement system, designed specifically for foundation joint repair.
Step 1: Precision Grinding
Our technicians began by grinding the joint at the water intrusion site using a diamond blade. We opened up a 3-inch vertical and 3-inch horizontal section along the joint. This allowed for the complete removal of surface contaminants, loose materials, and any hidden cracks that could continue to let in moisture.
Step 2: Installing Reinforced Fibermesh
Next, we installed 4.5 oz reinforced fibermesh across the entire affected area. The fibermesh adds structural strength and flexibility to the repaired joint, which helps resist future cracking and water penetration. This mesh also acts as a bonding layer between the cement coating and the foundation surface.
Step 3: Dual-Layer Waterproofing Cement Application
We then applied two coats of Basecrete waterproofing cement over the prepared area. Basecrete is a high-performance, waterproof cementitious coating ideal for foundation repairs. The dual layers ensure deep sealing of micro-cracks and long-lasting protection against groundwater infiltration.
The Result
✔ Dry and Protected Basement Closet
The joint is now fully sealed, with no signs of active water intrusion.
✔ Reinforced Structural Integrity
The Basecrete and fibermesh combination ensures added protection against shifting or movement in the foundation.
✔ Improved Indoor Air Quality
By addressing the moisture issue, the homeowner avoids the risk of mold, odors, or humidity buildup in their living space.
✔ Minimal Disruption
The project was completed efficiently with minimal disruption to the finished basement bedroom.
