Case Study: Water Intrusion Repair in Long Island, NY

• Location: Residential Home, Long Island, N
• Project Type: Basement Water Intrusion Repair
• Keywords: Long Island flooding, Long Island flooding contractor

1. Problem Observation

The homeowner began noticing recurring water pooling in the basement, particularly during and after heavy rainfall. The water was seeping through the basement’s block foundation wall, and the floor near the Bilco door opening was consistently damp. This water intrusion was causing concerns about potential structural damage, mold growth, and overall deterioration of the home’s foundation . The homeowner, having previously experienced Long Island flooding issues, realized this was a serious concern and sought professional help.

2. Initial Inspection and Diagnosis

Zavza Seal LLC, a trusted Long Island flooding contractor, was contacted to diagnose the issue. The team conducted a thorough inspection of the property, focusing on both the interior and exterior of the foundation.

• Interior Observations: Evidence of water staining on the basement floor, particularly near the Bilco door. There were clear signs of moisture penetration in the basement block wall.
• Exterior Observations: Cracks in the foundation wall and evidence of water seepage due to ineffective waterproofing. The surrounding soil grading was leading water towards the foundation, exacerbating the problem.
• Diagnosis: Water was infiltrating through the basement block wall and concrete floor adjacent to the Bilco door. The existing waterproofing measures had deteriorated over time, and the lack of a proper drainage system was contributing to repeated flooding during storms.

3. Proposed Solution by Zavza Seal LLC

The solution proposed by Zavza Seal LLC was a comprehensive repair and waterproofing system designed to eliminate the water intrusion issue permanently. The team outlined a detailed repair plan, which included:

• Exterior Excavation: The team proposed excavating along the full length of the foundation wall, a total area of 35 linear feet (LF) by 5 feet deep (D), with an additional excavation at the corner returning to the Bilco door opening (5 LF by 5 D). This excavation would expose the foundation down to the footing for thorough waterproofing.
• Waterproofing and Crack Repair:
  1. Once the foundation was exposed, the wall would be cleaned thoroughly to remove dirt and debris.
  2. A liquid waterproof membrane would be applied to the entire subgrade section of the foundation wall, ensuring long-lasting protection against water infiltration.
  3. All visible cracks in the cement plaster, both above and below grade, would be repaired to prevent any future water penetration.
• Protection Mat Installation: To enhance the waterproofing system’s durability, a protection mat would be installed over the liquid membrane before backfilling the excavated area to the original grade level.
• Sump Pump Installation:
  1. A new sump pump would be installed to ensure proper drainage in the basement. The sump pump would be connected to the existing discharge pipe, providing an efficient way to pump out any water that might accumulate near the foundation.
  2. Zavza Seal LLC would supply and install a high-quality sump pump to handle the water drainage, further preventing future flooding issues.

4. Implementation of the Solution

Zavza Seal LLC’s team worked efficiently to implement the proposed solution. The following steps were completed:

• Excavation and Foundation Waterproofing: The team excavated the exterior foundation wall, cleaned the surface, and applied a premium liquid waterproof membrane , which would protect the foundation from future water infiltration. The protection mat was then installed for added resilience.
• Crack Repair and Coating: All visible cracks were expertly repaired, both above and below grade. The exterior of the foundation received a fresh masonry coating, providing both aesthetic enhancement and additional weather protection.
• Sump Pump Installation: A new sump pump was installed, connected to the existing discharge pipe, ensuring that any excess water accumulating in the basement could be efficiently pumped out.
