Polyurea Concrete Crack Injection

Polyurea is 4x stronger than Epoxy. It is also 98% more flexible than Epoxy. The flexibility of the material makes it extremely durable and long-lasting. Since the material is flexible, it will not crack or peel, unlike Epoxy.

Polyurea and Urethanes are great for crack filling. Because polyureas’ elastomeric nature can accommodate concrete movement, the seal stays intact and does not crack or break off. They also begin to harden within minutes of injection. This reduces the chances of the material flowing out of an injected crack while still in liquid form, and even if some do leak out, the Polyurea will fill the void. 

Application temperature

Freezing temperatures will prevent epoxies from completely curing. Only use epoxies when the installation temperature is above 32 degrees F.

On the other hand, Polyureas will thoroughly cure even in freezing temperatures. Polyureas can cure at temperatures as low as -20 degrees F (-29 degrees C). This gives them the advantage over epoxies.

Appearance

Both filler types will discolor when exposed to UV radiation from sunlight or even some types of interior lighting. UV stabilizers can be added to our polyurea products to delay the onset of any discoloration.

With all the information in front of you, it’s easy to see why most people have turned away from epoxies and employed the use of Polyurea instead. If you would like to know more about our products, please fill out a form here and let us know how we can help.
