The City of Ketchikan has used IRR for patching potholes since last summer. Our crews are continually amazed at how well it has performed. We have not had a single patch ravel or come loose this winter. It is even better than the original asphalt.

The winter freeze thaw cycles with rain and snow has not phased the material at all. Chains do not even marr or scratch the patch. Overall, we couldn't be more pleased with IRR and we plan to have plenty of material on hand from now on.

Thanks for developing this amazing product. It has saved us a lot of money.

Harvey Hansen
