Why Is Polyurethane Foam Injection the JES Choice for Fixing a Concrete Porch?

The efficacy of polyurethane foam injection is backed by the United States Department of Transportation, which has been using it for concrete repair on roads and in other situations for more than 30 years. However, if that’s not enough to convince you of its benefits, you can look at those benefits for yourself.

These are the main reasons JES uses polyurethane foam injection for concrete leveling. 

Lightweight

One of the biggest downsides of pressure grouting is that it’s very heavy. The slurry mixture can weigh about 120 pounds per cubic foot. That means it’s very difficult for individuals to pump the slurry into the area in the first place.

Compare that to polyurethane foam injection, which can weigh around 4-6 pounds per square foot. This is largely because polyurethane foam expands 25-35 times its original size, which makes it a lightweight and effective option. 

Low Cost

One reason that both pressure grouting and concrete replacement aren’t the best options is that they’re both very expensive. Due to the amount of work and time required for them, they may not be affordable for many people. That can cause some to simply not pursue fixing their cracked floors.

Contrast that with polyurethane foam injection, which is very affordable. That’s one of the reasons the Department of Transportation uses polyurethane foam injection. It can take a beating, but it’s much less expensive than re-pouring concrete. 

Waterproof

Even though concrete is a strong material, that doesn’t mean it’s necessarily waterproof. Plus, the soil underneath the concrete isn’t waterproof; that’s one of the reasons your concrete may be sinking. When you pump in new concrete, you’re risking the same water-based concerns that you already have.

Instead, consider polyurethane foam injection, which is fully waterproof. One of the benefits of polyurethane foam injection is that you don’t have to worry about washout, which means it’s truly a fix that can keep your sunken concrete propped up for a long time. 

Quick Cure Time

A major downfall of both concrete replacement and pressure grouting is the cure time. You may need to stay off a brand-new concrete patio or a patio with pressure grouting for multiple days, with some requiring up to two weeks.

This is not so with polyurethane foam injection. Polyurethane foam makes it quick and easy for you to get on with your life. It can cure to its final state in only 15 minutes.
