UPM® Cold Mix offers numerous features and benefits to make repairs easily and cost-effectively.

UPM® customers see the value and savings in a higher quality material that works permanently vs. buying the cheapest cold mix available.

The product has become the industry standard after years of development and field testing. Wouldn’t you rather fix it right with UPM® than buy a cheaper product that requires added labor costs to repair the same holes over and over?

Do it right the first time and use UPM® Cold Mix as a permanent solution to your pavement and pothole repairs.
