Polyurethane Crack Injection
The best solution for most cracks on poured concrete foundations,is injecting expanding polyurethane into the crack from the inside. It penetrates into hairline cracks and contact with water makes it forcefully expand up to 20 times its volume to completely fill even wide cracks (up to 1/2″). The polyurethane foam remains flexible and allows for the natural movement of concrete.
Polyurethane is a great choice for minor cracks and is best used in poured concrete foundations. These foundations are typically found in older homes, although many construction and building companies still use this technique to save on building costs. Unfortunately, poured concrete is notorious for cracking as the home shifts on its foundation in response to differences in soil quality underneath your home. When this happens, cracks appear in your foundation and move vertically up your wall. It can take some time for these cracks to show, and even longer for leaks and flooding to occur. However, the time to address these issues is as soon as they appear.
Your Home Might Need Polyurethane Injections If:
- You notice cracks trailing up your wall from the ground
- One side or corner of your house is built on higher or lower ground than the rest
- You notice a specific area of your basement is wet (as opposed to an entire wall)
Polyurethane injections are the most cost-effective way of eliminating leaks and flooding in your home while cracks remain small. Don’t put off any work if you find cracks in your foundation. Give us a call and let us help you make an informed decision!
