Loresco backfills are produced exclusively for use as earth contact backfills in cathodic protection installation. The high carbon content in the Loresco products (greater than 99%), coupled with low resistivity, assures long system performance.

The standard Loresco Backfill product line includes several different compositions of earth contact backfill, providing an optimum product selection for the various types of Cathodic Protection installation and performance requirements.

• DW-1 for Surface System and Light Duty Semi-Deep Systems
• SC-2 for Enhanced System Performance
• SC-3 Modified with wetting agents added
• SW/SWK/SWS for Impressed Current Systems
• Many others available

Loresco PowerFill™ is an economical low-resistivity grounding backfill designed specifically for the electrical grounding industry. PowerFill™ is an economical solution for locations where acceptable earth resistance is difficult to achieve (i.e. < 1 ohm). It is highly conductive wet or dry and does not require moisture to lower the resistance of a grounding/earthing system. PowerFill™ carries an NSF certification (Certified to NSF/ANSI standard 60) enabling installation close to buried potable water systems. PowerFill™ also contains a corrosion inhibitor which forms a film on the copper cabling creating a barrier against corrosion.

PowerFillTM is designed to be used in conjunction with all standard copper grounding equipment allowing for a greater variance in design that would otherwise be uneconomical.

PowerFillTM can be poured in dry or pumped in slurry form. No tamping required. It is very user friendly. No special tools are required.
