Ultrafill is a low resistance carbon based backfill material, which
dramatically lowers ground system resistance in difficult soil
situations. Ultrafill contains no bentonite or concrete components,
which, in very dry conditions, can cause shrinkage around the
ground electrode, thus rendering it ineffective.
Ultrafill is ideal for use in rocky soil, sand, gravel or any other high
resistance soil conditions. It is also the ideal backfill material for
use around enhanced ground rods and ground grid systems.
Ultrafill may be used in a horizontal trench or grid, or in vertical
applications. Ultrafill is now available in durable, tear-resistant,
