• Location: Wheatley Heights, NY
• Project Type: Dry Well Drainage Installation
• Keywords: Dry well drainage, Dry wells for drainage, Dry well for drainage

1. Problem Observation

The homeowner in Wheatley Heights, NY, was facing significant water pooling issues at their basement stair landing. Every time it rained, water would accumulate at the base of the stairs, creating a major flooding concern. Over time, the water started seeping into the basement , causing structural worries and an increased risk of mold growth. The client reached out to Zavza Seal LLC, well-known for their expertise in dry well drainage solutions, to find a permanent fix for this recurring problem.

2. Initial Inspection and Diagnosis

Upon arrival, the Zavza Seal LLC team conducted a thorough inspection of the problem area to determine the root cause of the water accumulation. The inspection revealed several key issues:

• Pooling at the Stair Landing: The design of the basement stair landing was not conducive to proper water drainage. The concrete slab had insufficient slope, causing water to collect rather than flow away.
• Lack of Drainage Infrastructure: The stair landing lacked proper dry wells for drainage to handle excess water during heavy rains, leading to recurrent flooding.
• Structural Concerns: Prolonged exposure to standing water was starting to weaken the concrete, and water seepage into the basement raised concerns about potential water damage and mold.

3. Proposed Solution by Zavza Seal LLC

To address these issues, Zavza Seal LLC proposed installing a dry well drainage system at the basement stair landing. The solution would provide a long-term fix by efficiently channeling rainwater away from the stair landing and preventing further flooding. The proposed steps included:

• Concrete Slab Removal: The existing concrete slab would be cut and disposed of to prepare the site for excavation.
• Excavation and Gravel Bed Installation: The team would excavate to a depth of 3 to 4 feet and install a filtered gravel bed. This gravel bed would serve as a foundation for the dry well, ensuring that water would be filtered and directed into the well.
• Dry Well Installation: A dry well would be installed to capture and store excess water, allowing it to be absorbed naturally into the ground. This well would be the central component in eliminating water pooling.
• Storm Catch Basin and Aluminum Grate:
  1. An 18-inch storm catch basin would be installed above the dry well. The catch basin would trap and direct water into the dry well.
  2. A durable aluminum grate would be installed over the catch basin to prevent debris from entering the drainage system while allowing water to flow through freely.
• New Concrete Slab: A new 4,000 PSI high-strength concrete slab would be poured, level with the newly installed grate. The slab would be 4 inches thick, ensuring it could withstand heavy foot traffic and weather conditions.

This solution was designed to offer a robust and effective dry well for drainage system, minimizing the risk of water buildup in the future.

4. Implementation of the Solution

Zavza Seal LLC executed the plan with precision and efficiency. The project was completed in several phases:

• Concrete Removal and Excavation: The team began by cutting and removing the old concrete slab at the basement stair landing. Once the area was cleared, excavation work commenced to a depth of 3 to 4 feet. Careful attention was given to the dimensions of the excavation to ensure the proper fit for the dry well and catch basin.
• Gravel Bed and Dry Well Installation: The next step involved installing the filtered gravel bed. This bed was carefully laid to ensure proper filtration and stability for the dry well. The dry well was then installed, effectively positioned to capture and redirect any water from the landing.
• Catch Basin and Grate Installation: The team connected the dry well to the 18-inch storm catch basin and secured it with a sturdy aluminum grate. This combination would ensure that water could be collected and filtered efficiently while preventing debris from clogging the system.
• Concrete Slab Installation: Finally, the Zavza Seal LLC team poured a new high-strength concrete slab, level with the grate. The 4-inch thick slab was made from 4,000 PSI concrete, ensuring durability and longevity.
