|

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

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.

space. Or the holes are spaced to far apart.

the middle of the day when the temperature is at its
highest.

diameter exceeds recommended hole diameter.
