GROUNDMAX™
BURNDY
®
GROUNDMAX™ is an economi-
cal solution for areas with very difficult
grounding issues. BURNDY
®
GROUND-
MAX™ is highly conductive in a wet or dry
application and does not require moisture to
lower the resistance of your grounding sys-
tem. BURNDY
®
GROUNDMAX™ contains a
corrosion inhibitor which forms a film on cop-
per, creating a barrier against corrosion.
BURNDY
®
GROUNDMAX™ can be poured
in dry or pumped in slurry form. No tamping
required. It is very contractor friendly. No
special tools required.

Thickness of
BURNDY
®
GROUNDMAX™
(Inches)
To calculate the lbs. of material required to fill a trench:
• Determine desired thickness.
• Move to the right until you are under the known width of the trench. This number will be the
weight of the material in lbs./linear ft.
• Take this number and multiply by the length of the trench in feet. Your answer will be the
amount of BURNDY
®
GROUNDMAX™ material required to fill the trench to the desired level
in lbs.
Example:
Thickness: = 6 inches
Width
= 18 inches
54.6 lbs. per linear ft. (from the table above)
Answer
= 54.6 lbs. per linear ft. x 25 ft. trench = 1,365 lbs. of BURNDY
®
GROUNDMAX™
= 28 (50 lb.) bags of BURNDY
