Be sure that all the wire mesh or reinforcing bars are set approximately two
inches (51 mm) off the bottom of the form.
If required, use local practices to treat the area below the mounting pad and
for two feet around the perimeter against insect infestation.
Use a high-early strength concrete mix so that you can place the cabinet
three days after concrete pouring. Coarse aggregate used in the concrete is
graded from 3/4-in. to No. 4 only. The compression strength of the concrete
must be a minimum of 4000 psi as determined by ASTM C39 test of
compression strength of concrete cylinders.
Pour the concrete. Finish the concrete so that the entire surface is flush with
or 1/4 inch below the top of the template mounting plates.
Note: Do not put a crown in the concrete surface.
Wait for a minimum of three days for the concrete to cure before cabinet
installation, or according to the type of concrete used and local practices.
