Loresco Flexfill

Loresco type FlexFill™ is designed for use around continuous, long-line impressed current anodes. FlexFill™ is the result of extensive laboratory testing combining the rugged requirements of field installation with the demanding performance characteristics required for long-line anodes.

The production of FlexFill™ begins with the critical selection of a base carbon material which meets exacting standards. Calcination of the base material is strictly controlled according to Loresco quality control standards. Sizing of FlexFill™ during the manufacturing process is also carefully controlled to meet the requirements of conductive backfill used with long-line impressed current anodes. All surfaces of FlexFill™ are modified with a conductive coating which maximizes the electronic flow between FlexFill™ and the long-line anode. In effect, this maximizes the life of the anode.

FlexFill™ is a performing backfill medium designed specifically for use with impressed current long-line anodes. Advanced particle selection technology, enhanced surface modifications and rigid production controls all combine to ensure that FlexFill™ surpasses your performance requirements.

FlexFill™ is simple to install either by pouring or by subsurface displacement with gravity flow. FlexFill™ has been designed to be placed by either method with no additional steps necessary to create a successful conductive medium. No vibrating or compacting is required.
