Project Location: Bethpage, NY
Service Category: Basement Waterproofing, Structural Crack Repair
Client Concern: Water intrusion and visible foundation cracks in the basement, boiler room and kitchen/living space

---

Project Overview

A homeowner in Bethpage, NY, contacted Zavza Seal LLC with concerns about water intrusion in the basement, specifically in the boiler room and the kitchen/living room area. Upon inspection, our team identified three (3) visible vertical cracks on the exterior of the foundation wall, which were the source of basement leaks and posed a potential structural risk if left unaddressed.

The homeowner required a permanent solution that addressed the root cause of the water infiltration and restored the integrity of their basement structure.

Scope of Work

Basement Area – Foundation Crack Repair & Waterproofing

To eliminate water penetration through foundation cracks and prevent further damage, we performed the following:

1. Interior Wall Access:
   
   • Opened the sheetrock/drywall inside the affected basement areas to access the concrete foundation wall directly.
     
   • Ensured careful removal to minimize unnecessary demolition.
     
2. Surface Preparation:
   
   • Steel brushed the cracks to remove loose materials and expose bare concrete for maximum adhesion.
     
   • Cleansed the surface to ensure effective bonding of repair materials.
     
3. Injection Port Installation:
   
   • Drilled injection ports every 6 inches vertically along the length of each crack.
     
   • This step enabled a deep-set application of waterproofing material, ensuring long-lasting protection.
     
4. Waterproofing Crack Repair:
   
   • Injected waterproofing solutions and overlaid the entire area with mesh-reinforced Basecrete waterproof cement.
     
   • This method provides a flexible and durable seal that adapts to minor wall shifts and moisture pressure.
     
5. Interior Finishing:
   
   • Reinstalled drywall in all treated areas, taped and compounded.
     
   • While final sanding and painting were left to the homeowner, we ensured the space was fully ready for finishing.
     
   • Molding was replaced to restore the room to its original appearance.

Boiler Room – Chimney Wall Crack Repair

In addition to basement waterproofing, our team addressed a crack in the flue pipe wall joint connected to the chimney. The repair involved:

• Application of high-strength hydraulic cement to seal the wall joint around the flue pipe.
  
• This ensured safe and watertight sealing, minimizing risks of gas leakage or further water infiltration through chimney structures.
