Project Overview
This foundation repair project was completed by the team at Zavza Seal in Mastic, NY. The homeowner was dealing with active water intrusion through two structural cracks in the foundation wall. Water was entering the basement during rain events and causing moisture issues inside the living space.
The goal was to fully stop water intrusion, restore structural integrity at the cracks, and return the interior wall to a clean and finished condition.
Problem
The homeowner reported the following issues:
- Visible water seepage through two foundation wall cracks
- Dampness and moisture inside the basement
- Deterioration around the cracked areas
- Concerns about long term structural damage
On inspection, the team identified:
- Two active structural cracks in the foundation wall
- Loose concrete, efflorescence, and dirt along the crack lines
- Water migration paths entering through the wall under pressure
These conditions are common in foundation crack repair projects in Mastic, NY, especially in homes exposed to seasonal rainfall and soil pressure.
Solution
Our team followed a detailed structural repair and waterproofing process to permanently seal the cracks and prevent future leakage.
Interior Repair Process
- Opened interior sheetrock to fully expose both foundation cracks
- Ground both sides of each crack to remove loose material, salts, and contamination
- Prepared clean concrete surface for proper bonding
- Installed injection ports at 6 inch vertical spacing from top to bottom
- Injected structural epoxy and urethane materials to seal the cracks internally
- Applied one layer of Basecrete waterproofing cement over the repaired cracks
- Installed 4.5 oz reinforced fiberglass mesh for added strength
- Applied a second layer of Basecrete waterproofing cement to fully seal and reinforce the surface
- Installed new sheetrock with taping and compound finishing to restore the interior wall
Exterior Repair Process
- Patched both above grade exterior crack locations
- Sealed exterior entry points to reduce future water penetration
- Restored surface protection on the outside foundation wall
Result
After completion of the repair:
- Water intrusion through both cracks was fully stopped
- The foundation wall was structurally reinforced
- Basement interior was restored to a clean finished condition
- The homeowner gained long term protection against moisture damage
This type of foundation crack repair in Mastic, NY helps prevent costly structural deterioration and improves overall basement health.
