Dexpan Frequent Asked Questions (FAQs)


How much area will a 44lbs box of Dexpan® fill?

A 44lbs. Box of Dexpan® would cover approximately 34-36 linear feet.


How big or small can I drill my holes?

For best results it is recommended to use a 1½” Diameter hole.

It is not recommended to exceed 2½” or go less then 1” in diameter.


How far apart can I space my holes?

Recommended spacing is as follows:

  • Depending on the density of the rock/concrete will determine the hole spacing. If you are working with reinforced concrete, it is highly recommended to use 1’ centers. In rock, Dexpan® has been known to range in spacing up to 2’!!  It is recommended to test out the density of your stone first by drilling holes starting at 12”, then to 16” then to 18” then to 24” then determine what will work best for your stone.

  • Depending on your hole size will also determine your spacing. Using a 1½ diameter hole we recommend that the holes are 12” apart in reinforced concrete. Using a 2” diameter hole you can extend out to 18” – 24” spacing, once again depending on the density of the stone.

  • Remember that Dexpan® is a “controlled agent”, you may cut your stone to your desired size, by just making sure that your lines are set on 1’ spacing.


How do I determine what type of Dexpan® to use?

Determine the type to use by checking the Rock/Concrete temperature.

(Dexpan III: 23º-50ºF, Dexpan II: 50º-77º, Dexpan I: 77º-104ºF)

Best time to apply Dexpan® would be early in the morning or late in the afternoon, this is HIGHLY recommended in extremely hot temperatures.

What causes the Dexpan® to blow out?

  • You may get a blow out if there is no expansive space. Or the holes are spaced to far apart.

  • You can get a blow out if you do your application in the middle of the day when the temperature is at its highest.

  • You may also experience blow outs if you hole diameter exceeds recommended hole diameter.

  • You may also experience blow outs if using core drill bits. Note: There has been much success using core bits, this is just a possibility.
