Overview
Our team was hired to repair a structural crack in a foundation wall at a residential property in Mt. Sinai, NY. The homeowner was concerned about the crack’s potential impact on the home’s stability and the risk of water intrusion. This case study outlines how we identified the problem and implemented a durable solution using advanced materials and techniques.
The Problem: Structural Foundation Crack with Water Seepage
The homeowner noticed a significant crack running approximately 9 linear feet along the foundation wall. The crack showed signs of previous patching that had failed over time.
During inspection, we determined:
✅ The old sealant was deteriorating and no longer effective.
✅ The crack was allowing water seepage into the basement.
✅ The structural integrity of the wall was compromised in the cracked area.
Without professional intervention, this crack could have widened further, increasing the risk of serious foundation damage and more severe water problems.
The Solution: Structural Epoxy Injection and Waterproofing
We proposed a comprehensive foundation wall crack repair plan designed to restore structural integrity and create a watertight barrier.
1. Preparation of the Crack Surface
We began by grinding and removing all the old sealant from the crack using diamond blades. To properly prepare the surface, we chased the crack to clean out all loose and damaged material and fully expose the bare concrete. This preparation ensured that the repair materials would bond securely to the wall.
2. Drilling of Injection Ports
Using precision diamond bits, we drilled injection access ports along the length of the crack at 6-inch intervals. These ports allowed us to deliver the epoxy and urethane deep into the crack to fill voids and restore strength.
3. Epoxy and Urethane Injection
We injected the crack with specially formulated epoxy and urethane. This dual injection process served two purposes: reinforcing the structural integrity of the wall and sealing the crack against water intrusion.
4. Waterproofing Cement and Fiberglass Reinforcement
After the injection was complete, we applied a layer of high-strength 7050 psi waterproofing cement over the entire length of the repaired area. We then installed a 4.5-ounce fiberglass layer along the full crack length to further reinforce the wall and prevent future cracking. Finally, a second layer of 7050 psi waterproofing cement was applied to seal the repair completely.
Results: Stronger, Waterproof Foundation Wall
