Problem:
The homeowner in Melville, NY was experiencing water intrusion at the floor joint where the foundation wall meets the basement slab. This issue often led to moisture seeping into the basement during heavy rainfall, raising concerns of long-term damage and mold growth. The affected area measured approximately 14 linear feet, and the leak was located at the base of the foundation wall where structural stress and age had compromised the joint.

Solution:
Work Area: Foundation Wall Base (Approx. 14 Linear Feet)
To address the water intrusion and restore the integrity of the joint, our team executed a precision-based waterproofing repair. We started by grinding 3 inches vertically along the foundation wall and 3 inches horizontally along the basement floor at the joint. This allowed for proper adhesion and depth for waterproofing application.

Once the surface was properly prepared, we applied a mesh-reinforced Basecrete waterproof cement system. This advanced material offers both sealing and structural reinforcement, ensuring long-term protection against water penetration. The mesh reinforcement adds strength and flexibility to the repair, allowing it to accommodate slight movements in the structure without compromising the seal.

This targeted intervention effectively sealed the vulnerable joint and eliminated the water intrusion issue. The client was satisfied with the outcome and now enjoys a dry, secure basement environment.
