What Is Concrete Crack Injection?
Crack injection is a service provided by professional basement waterproofing companies. However, not all companies are the same and not all offer the same type of crack injection like we do here at StayDry. You see, we utilize a high-pressure injection system, where most other companies use a low-pressure system. Additionally, we use a quality polyurethane to fill the concrete cracks rather than the epoxy most competitors use. As far as the crack injection process goes, we still set ourselves apart from others. With this, let’s take a closer look at the process.
Both horizontal and vertical cracks can be dealt with through crack injection provided the crack is not too large and no serious underlying foundational issues have occurred. If not, the crack will first be covered by a temporary surface bond. The purpose of this is to make sure that the polyurethane injected into the crack remains long enough to set. Holes are then drilled into the area of the wall where the crack is, approximately every 12 inches or so extending from the top to the bottom of the crack at cross paths. Next, special brass packer ports must be inserted into the holes so a machine can be affixed to those ports.
Once the machine has been affixed, the packers are tightened so the polyurethane is not able to exit but is all directed into the crack. Professionals begin working from the bottom up, injecting the crack with the polyurethane until it is visible from above. The polyurethane material has a 40:1 positive expansion ratio, which means that even after it has been injected and fully fills the crack, it can continue to expand from the interior through to the exterior. This will serve as a very effective barrier preventing the water from coming in and completely sealing the crack.
After the port has been filled, the surface bond remains on the wall for a total of 24 to 48 hours. This ensures the polyurethane has time to set completely and fill the crack in full. The surface bonds and ports are easily removed after this period by the homeowner. The process is quick, simple and often cost effective. More Importantly, it can help to ensure your Michigan home’s foundation stays strong and your basement stays dry.
