Basement Foundation Crack Repair and Waterproofing
The Problem
A homeowner in Port Jefferson Station, NY contacted Zavza Seal after noticing water intrusion in their basement foundation wall. The issue stemmed from a structural crack that had developed over time, allowing moisture to penetrate the foundation. This not only created visible dampness inside the basement but also raised concerns about long-term structural stability and mold growth.
The homeowner needed an experienced team to not only stop the water infiltration but also reinforce the integrity of the foundation wall.
Our Solution: Structural Crack Repair and Waterproofing
At Zavza Seal, our team of waterproofing specialists developed a customized repair plan to eliminate the water intrusion and reinforce the crack using advanced injection and waterproofing techniques.
Step 1: Crack Preparation
We began by grinding the crack using a diamond blade to open up the affected area and remove all loose or compromised material. This ensured a clean and receptive surface for injection.
Step 2: Precision Drilling
Our technicians drilled access points every 6 inches vertically along the full length of the crack, preparing the wall for epoxy and urethane injection. These drill points allowed for deep penetration of the waterproofing material into the core of the crack.
Step 3: Epoxy and Urethane Injection
We then injected high-strength epoxy and urethane formulations into the crack to fill all voids, permanently sealing the crack from water intrusion while also restoring the structural integrity of the wall. This step ensures long-lasting protection and reinforcement.
Step 4: Mesh-Reinforced Waterproofing Application
To provide added defense, we covered the entire repaired crack with a strip of 4.5 oz mesh-reinforced Basecrete waterproof cement. This created an external barrier over the sealed crack, protecting the area from future moisture issues.
Step 5: Exterior Crack Patching
In addition to the interior work, we also patched the two above-grade sections of the cracks located on the exterior of the foundation wall. This completed the waterproofing envelope and protected the foundation from outside elements.
The Result
✔ No More Water Intrusion
The basement is now fully dry, with no signs of leakage or moisture buildup after rainfall.
✔ Strengthened Foundation
The epoxy and urethane injection strengthened the crack and restored the wall’s original load-bearing capacity.
✔ Long-Term Waterproofing Protection
The mesh-reinforced Basecrete coating and exterior patching deliver added resilience, protecting against future foundation damage.
✔ Improved Home Value
By eliminating structural and water concerns, the homeowner gained peace of mind and boosted the property’s long-term value.
