PowerFillTM is an economical ground enhancement material to
substantially lower earth resistance of copper-clad ground
rods and copper grounding systems.
PowerSetTM is designed for use by the electrical grounding
industry when a permanently-setting ground enhancement
material for use with copper-clad ground rods and copper
grounding systems is specified.
Typical designs for both products can be viewed through
the graphic links shown here.

Grounding Enhancement Backfills
In order to access the effect of corrosion inhibitors used with
grounding enhancement backfills, four identical copper strips
were cleaned and placed in individual containers with each strip
placed in a different environment for a period of 1 year. Tap
water was periodically added as required to replace water lost
due to evaporation. The picture below was taken after removing
and cleaning of the copper strips after exactly 1 year. The electrode
numbers and environments were as follows:
#1 - Tap water
#2 - Carbon covered with tap water-no inhibitor
#3 - LORESCO PowerFillTM covered with tap water
#4 - LORESCO PowerSetTM covered with tap water
The copper strip exposed to coke with no inhibitor (#2) exhibited
a 20% loss in weight due to significant corrosion as evidenced
by the photograph. Significant thinning of the strip is evident
in the photograph. The copper strip exposed to the tap water
(#1) also exhibited some minor evidence of corrosion. However,
both of the copper strips exposed to the LORESCO inhibited grounding
enhancement backfills (#3 and #4) showed no corrosion. The protective
surface film remained intact.
