Polyurethane is a mixture of organic compounds that can be created into a foam. While this foam is often used in insulation, bedding, and footwear, it can also be injected into cement for crack repair. If the cement around your home is cracked and damaged, here are four frequently asked questions that will help you determine if polyurethane foam injection is the right choice.

Common Questions About Polyurethane Foam Injection

What is polyurethane foam injection?

In this process, also known as concrete leveling, holes are drilled into a slab of cracked or sunken cement and filled with foam injection ports. Through these ports, polyurethane foam is then injected beneath the slab until it rises. When the concrete is completely level, the holes are sealed with cement.

How long does it take?

Since the polyurethane foam used for crack repair and concrete leveling cures in 15 minutes, small residential projects usually take only a few hours. However, finish times may vary if you are filling a large slab with more significant imperfections.

What are the benefits of using polyurethane foam?

Polyurethane foam is lightweight but durable. It is also an affordable, permanent solution for cement crack repair that doesn’t require entire slab replacement. Additionally, this material creates a moisture-resistant seal between the soil and the concrete slab. Since polyurethane foam lasts indefinitely, you won’t ever need to worry about erosion caused by moisture underneath the slab.

Is polyurethane foam environmentally friendly?

Polyurethane is a smart material for environmentally conscious homeowners since it is made from organic compounds that don’t change the pH of soil or water. Thanks to its long life span, it is also less likely than other types of plastic to be discarded in a landfill. Additionally, polyurethane foam can be recycled and turned into underlay material for carpets.
