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
Is ideal for use in rocky soil, sand, gravel or any other
high resistance soil conditions. It is also the ideal backfill
