Project Overview: In this case study, we examine a recent foundation waterproofing project completed by Zavza Seal LLC for a homeowner in Commack, NY. The homeowner contacted us with concerns about moisture intrusion in a utility room, which had extended into an adjacent bedroom. Our team assessed the situation, diagnosed the root cause, and implemented a waterproofing solution to secure the affected areas.

Location: Commack, NY
Scope of Work: Utility room and bedroom foundation wall waterproofing (12 linear feet total)

Homeowner Observation

The homeowner in Commack noticed persistent moisture along the base of the foundation wall in their utility room, which was causing concern as the issue appeared to be extending into an adjoining bedroom. Visible signs of dampness and moisture infiltration along the lower section of the wall were the primary symptoms, and the homeowner was understandably eager to prevent further water damage and protect their property from mold and structural issues.

Zavza Seal’s Assessment and Diagnosis

Upon visiting the property, our team conducted a thorough inspection of the foundation wall, carefully analyzing the utility room and bedroom areas. The main concern was moisture penetration through the concrete foundation, particularly affecting the lower section of the wall. After evaluating the layout, wall condition, and visible dampness patterns, we identified that water infiltration was occurring at the base of the wall, primarily due to a lack of adequate waterproofing.

The affected area was approximately 4 linear feet in the utility room, extending an additional 8 feet into the bedroom, where the green-painted wall had also shown signs of moisture.

Implementing a Waterproofing Solution

To address the issue effectively, we followed a multi-step approach to secure the foundation wall. Here’s a breakdown of the steps our team implemented to ensure a long-lasting solution:

1. Preparing the Work Area:
   The first step involved preparing the area by removing the lower 4 feet of sheetrock in the bedroom to access the underlying concrete wall. This allowed our team to fully inspect the foundation and identify any additional cracks or weak points along the Subject Area. We also removed the framing if it interfered with the application, ensuring a clean working area.
2. Concrete Surface Preparation:
   With the sheetrock removed, we thoroughly cleaned and ground the concrete wall along the Subject Area, focusing on the areas where the waterproofing would be applied. Grinding the concrete ensured a clean, even surface that would allow for better adhesion of the waterproofing materials.
3. Application of Waterproofing Cement:
   Our next step was to apply a coat of waterproofing cement along the joint, extending 3 inches on each side. This initial layer created a seal and added the first level of protection against moisture infiltration.
4. Reinforcing the Waterproofing Layer:
   After the first coat of waterproofing cement dried, we installed a 4.5 oz reinforced fiber mesh over the area. The fiber mesh provided structural reinforcement to the waterproofing layer, enhancing its durability and helping to resist any future water pressure.
5. Second Waterproofing Cement Application:
   Finally, we applied a second coat of waterproofing cement over the reinforced fiber mesh. This second layer solidified the barrier, ensuring comprehensive coverage and protection along the 12-foot foundation wall.
6. Observation Period:
   To confirm the effectiveness of our work, the homeowner agreed to leave the concrete wall exposed for a few rain cycles. This observation period would allow us to identify any remaining weak points, guaranteeing that the wall would remain dry before any framing or sheetrock was reinstalled.
