It is believed the blaze - which caused severe damage to the first floor - was caused by a plug-in heater setting bed
Use ordinary washed concrete sand for the setting bed
. Figure on 1 cu.
To determine excavation depth, add the paver dimension, the thickness of any sand or mortar setting bed
, and the thickness of the base.
One key is to never use sand in these systems; since sand provides an extremely tight pore size it will seal off with a small amount of sediment, so we use a small (1/16-inch to 1/8-inch) clean, crushed limestone as the setting bed
and the granular material to backfill the void spaces between the pavers.
To determine how deep you should excavate, add the paver thickness (anywhere from 1 1/2" to 3"), the depth of any sand setting bed
(typically 1"), and the thickness of the base (typically 4").
It is believed that the blaze, which badly damage the first floor of the home, was caused by a plug-in heater setting bed
However, alternatives do exist to use of an aggregate base with a setting bed
for some pavement types.
And have gravel or sand delivered to use as a setting bed
for the stone (Photo 2) as well as topsoil to fill behind the wall (Photo 5).

Or use leftover sand from the setting bed
, if it's dry.
