Foundation Crack Injection Process

Here's Exactly How We Fix It

First, we assess the crack type and cause. Not all foundation cracks are the same—settlement cracks need different treatment than shrinkage cracks. We determine whether you’re dealing with structural movement or just concrete curing issues.

Next comes the injection process. We clean out loose debris, install injection ports at strategic points, and use high-pressure polyurethane or epoxy injection to fill the entire crack from inside out. The material expands to create a waterproof seal that’s actually stronger than the surrounding concrete.

Finally, we test the repair and clean up. You get a warranty-backed solution that stops water infiltration and prevents the crack from reopening. Most repairs are completed in a few hours with minimal disruption to your property.

Professional crack injection using polyurethane or epoxy creates a permanent seal that typically lasts the life of your foundation. The injected material is designed to move slightly with normal foundation settlement while maintaining the waterproof barrier. Most of our Westbury foundation crack repairs are still performing perfectly after 10+ years. The key is using the right injection material for your specific crack type and soil conditions. Cheap DIY crack fillers fail because they can’t handle Long Island’s freeze-thaw cycles, but professional injection techniques are engineered for our climate.
Yes, most foundation crack repairs can be completed from the interior side without excavating around your foundation. Interior crack injection is often more effective because we can control the injection pressure and material flow more precisely. We only recommend exterior repairs when the crack extends significantly above grade or when there are drainage issues that need to be addressed from outside. Interior repairs also avoid disrupting your landscaping, driveways, or walkways. The injection material penetrates through the entire wall thickness, creating a complete seal regardless of which side we inject from.
Epoxy injection is rigid and provides maximum structural strength—ideal for cracks caused by settlement or structural movement. It essentially welds the crack back together and restores the concrete’s original strength. Polyurethane injection is flexible and expands to fill the entire crack, making it perfect for active leaks or cracks that might experience slight movement. For most Westbury foundation cracks, we use polyurethane because it handles our soil movement better and provides superior waterproofing. We’ll assess your specific crack and recommend the right material based on the cause and location.
Foundation crack repair costs depend on the crack length, location, and injection method required. Most single crack repairs range from a few hundred to around a thousand dollars—significantly less than dealing with water damage or structural issues later. Multiple cracks or complex structural repairs cost more, but we provide detailed written estimates before starting any work. The investment usually pays for itself by preventing water damage, mold issues, and property value loss. We’ll assess your specific situation and give you transparent pricing with no hidden fees or surprise charges.
Small hairline cracks can be normal concrete shrinkage, but they can also be early signs of foundation settlement or water infiltration points. The key is determining whether the crack is stable or growing. Even hairline cracks can allow water seepage during heavy rains, leading to basement moisture and potential mold issues. In Long Island’s clay soil conditions, small cracks often expand during freeze-thaw cycles. It’s worth having them evaluated—catching foundation issues early is always less expensive than waiting until they become major structural problems.
Professional foundation crack repair with proper documentation actually protects and can increase your home’s value. Home inspectors and potential buyers see completed foundation repairs as a positive—it shows you’ve maintained the property and addressed issues properly. Unrepaired foundation cracks, however, are major red flags that can kill deals or force price reductions. We provide detailed repair documentation that you can show to inspectors or buyers, demonstrating that the work was done professionally with warranty coverage. Proper foundation maintenance is essential for protecting your property investment in Westbury’s competitive real estate market.
