Reasons To Try A Polyurethane Foam Injection Instead of Concrete Replacement

  1. It 's easy.

From the time a polyurethane form is placed around your existing concrete to the time the finished piece is removed, it takes three weeks. It includes curing time. While this is a little more time than pouring new concrete, one of our customers said it took him six years to find time to build on his year-round lakefront property. Saving THAT much money and aggravation could easily be worth working with a contractor for three weeks instead of only 1 or 2 days like you would if you were doing a new concrete pour.

  1. It was less expensive.

Pouring our polyurethane foam injection method costs 5-10% less per square foot than labor-only concrete replacement. Also, if you are doing it yourself, it's much more convenient to use polyurethane from injection versus concrete replacement. Once you've spent that much time pouring concrete, you might as well save even more and get it right the first time! It's hard to be proud of a concrete pour, and most people don't even bother.

  1. It 's super fast.

Concrete is one of the slowest methods to repair a sidewalk. After preparing your substrate and ensuring your forms are properly wrapped, the curing process takes three weeks before the sidewalk can be used again (1 week for sun exposure). In contrast, the polyurethane form method only takes 24 hours before the sidewalk can be used. (This may vary for each batch of polyurethane)

  1. It's safe and durable.

These forms are made from 100% recyclable plastic. Also, they're UV reactive and won't absorb moisture, so they'll last a LONG time - even when not in use! And because they are UV reactive, they will continue to act as a sunscreen on your concrete - protecting it from being overexposed to sunlight. 

  1. It 's green.

The polyurethane foam injection method is 100% non-toxic, environmentally friendly, and easy to use. When it comes to concrete, Sunray is the best way to brighten the look of your old, faded concrete. 

We believe the only way to repair a sidewalk correctly is with Polyurethane Foam Injection. These forms are made from 100% recyclable plastic and will protect your concrete for years without absorbing water, so it will not rot like bricks. Also, since they are UV reactive, they will continue to act as a sunscreen on your concrete - protecting it from being overexposed to sunlight. Because of the benefits of using these forms in place of traditional concrete replacement, we believe that this method is safer and more environmentally friendly, and much more cost-effective than replacing the sidewalk with new concrete.
