Client: Homeowner in Brooklyn, NY
Project Location: Brooklyn, NY
Service Provider: Zavza Seal LLC
Project Scope: Foundation waterproofing, HVAC ejector line separation, and downspout maintenance.

Project Overview

A homeowner in Brooklyn, NY, reached out to Zavza Seal LLC to address foundation waterproofing concerns and drainage system inefficiencies. The client reported moisture issues along the exterior foundation wall joint and an ineffective downspout system that contributed to water pooling around the foundation. Additionally, the HVAC ejector line was directly connected to the downspout, creating a dependence that needed to be eliminated.

Challenges

1. Foundation Water Seepage: The exterior foundation wall joint exhibited signs of water penetration and deterioration, requiring immediate waterproofing measures.
2. HVAC Ejector Line Dependence: The existing setup linked the HVAC ejector line to the downspout, potentially causing drainage inefficiencies.
3. Blocked and Unsecured Downspout: The North-West corner downspout was clogged, impacting water flow and leading to potential structural damage.

Solution Implemented

Subject Area A: Exterior Foundation Wall Joint (25 linear feet from the North-West corner along the West wall toward the South-West corner, and 7 linear feet from the North-West corner along the North wall toward the North-East corner)

• The team ground the surface of the Wall/Floor joint to remove all damaged and loose materials, ensuring proper adhesion for the new waterproofing application.
• Two layers of Basecrete waterproofing cement were applied, forming a durable, water-resistant barrier that prevents future water infiltration.

Subject Area B: HVAC Ejector Line

• The existing ejector line was cut near the downspout to remove its reliance on the shared drainage system.
• A 90° PVC elbow was attached to redirect the ejector line directly to the ground, improving overall drainage efficiency and reducing dependency on the downspout.

Subject Area C: Downspout on the North-West Corner (Approx. 25 ft high)

• The gutters were thoroughly cleaned to eliminate debris and allow unimpeded water flow.
• The downspout was snaked to remove any blockages, restoring its full functionality.
• The downspout was securely fastened to the facade to ensure long-term stability and prevent future detachment or damage.

A before and after comparison shows the repair work where the foundation wall joint was sealed and the downspout was extended, cleaned and fixed.

Results & Client Satisfaction

Following the implementation of these solutions, the homeowner observed a significant improvement in water drainage and foundation protection. The waterproofing treatment reinforced the foundation against moisture infiltration, while the HVAC ejector line modification optimized water flow management. The cleared and secured downspout now efficiently directs rainwater away from the structure, mitigating potential water damage.
