The Challenge:
A homeowner in Manorville, NY, was experiencing persistent water intrusion at the basement wall/floor joint, which was further exacerbated by water seeping through previously patched anchor holes in the concrete slab. This issue was causing dampness, mold growth, and structural concerns.
Client Observation:
The homeowner noticed visible water stains and dampness along the basement wall/floor joint, accompanied by a musty odor. Additionally, they observed water seeping through patched anchor holes in the concrete slab, indicating a more significant underlying problem.
Zavza Seal Diagnosis:
The Zavza Seal team conducted a thorough inspection of the affected area to identify the root causes of the water intrusion. They determined that the primary culprits were:
- Compromised wall/floor joint: The joint between the basement wall and floor had deteriorated, allowing water to penetrate.
- Inadequate anchor hole repair: The previously patched anchor holes were not providing sufficient protection against water intrusion.
The Solution:
To address these issues, Zavza Seal implemented the following repair plan:
- Surface Preparation: The affected area was chased and ground with a diamond blade to remove efflorescence, dirt, and mold, creating a clean surface for the waterproofing materials.
- Waterproofing: A coat of Basecrete waterproofing cement was applied to the exposed surface to seal the wall/floor joint and prevent further water penetration.
- Reinforcement: Reinforced fiberglass mesh was installed to strengthen the repaired area and provide additional protection.
- Anchor Hole Repair: The existing anchor bolts were drilled open, and hydraulic cement was injected to fill the holes and waterproof them. The cement was then troweled to achieve a smooth finish that blended seamlessly with the surrounding floor.
By addressing both the structural integrity of the wall/floor joint and the anchor holes, Zavza Seal was able to effectively resolve the water intrusion problem and prevent future damage.
