Introduction:

This case study details the successful repair of a concerning vertical crack in a Brooklyn basement, undertaken by Zavza Seal LLC. The extensive crack, measuring approximately 15 feet from floor to ceiling, posed a significant threat to the structural integrity of the foundation and allowed water infiltration. Through a meticulous process of inspection, diagnosis, and repair, Zavza Seal LLC restored the basement wall and provided the homeowner with lasting peace of mind.

Client Concerns:

The homeowner contacted Zavza Seal LLC after discovering a large vertical crack running along the entire east side of their basement cinder block wall. Their primary concerns were:

• Water Leakage: The crack allowed water seepage into the basement, potentially leading to moisture damage, mold growth, and a damp, unpleasant environment.
• Structural Integrity: The extensive size of the crack raised concerns about the structural stability of the foundation walls.

Onsite Inspection and Assessment:

A certified Zavza Seal LLC inspector visited the property to assess the situation firsthand. The inspection included:

• Visual Examination: A thorough visual examination of the crack, noting its size, location, and any visible signs of water damage.
• Moisture Detection: Utilizing moisture detection tools to identify any hidden moisture issues within the wall.
• Foundation Assessment: Evaluating the overall condition of the foundation to determine if the crack was an isolated issue or indicative of a broader structural problem.

Diagnosis:

Based on the inspection findings, the Zavza Seal LLC team diagnosed the problem as a large structural crack in the cinder block wall. This crack required immediate attention to prevent further water infiltration and potential structural concerns.

Proposed Solution:

To address the crack and restore the basement wall, Zavza Seal LLC recommended a comprehensive repair plan involving several key steps:

• Surface Preparation: Extensive surface preparation using diamond blades to remove paint, loose material, and any foreign objects from the affected area. This creates a clean and well-bonded surface for the repair materials.
• Crack Stitching: Cutting deep slots perpendicular to the crack at 12-inch intervals throughout its entire length. These slots act as channels for the structural epoxy and carbon fiber stitches.
• Structural Epoxy Injection: Filling the newly cut slots with a high-strength structural epoxy resin. This epoxy reinforces the crack from within, preventing further movement and water infiltration.
• Carbon Fiber Reinforcement: Installing non-corrosive carbon fiber stitches within the epoxy-filled slots. These high-tensile strength stitches provide additional structural support, literally pulling the crack closed with a capacity of 6,500 pounds each.
• Waterproofing Membrane: Applying a thick coat of 7,000 PSI waterproofing cement to the entire affected area. This waterproof barrier prevents future water seepage through the crack.
• Reinforced Mesh and Finishing Touches: Laying a layer of reinforced fiber mesh 4.5 oz. on top of the wet waterproofing cement for added strength. Finally, applying a second coat of waterproofing cement to ensure complete coverage.
• Painting: Completing the project with a fresh coat of paint on the repaired area, restoring a finished appearance to the basement wall.
