EnviroCoke IV™ combines the conductive properties of natural round grain Calcined Fluid Petroleum Coke particles with the low permeability properties of grout. The Coke particles are specifically sized to form the main conductive structure of the electrically conductive grout. To enhance the conductivity properties of EnviroCoke IV™, other forms of high quality carbon are added to the composite mixture. Further additives make installation easier by minimizing the apparent viscosity of the slurry. The additives insure the compatibility of EnviroCoke IV™ with equipment normally used to install cathodic protection systems.

EnviroCoke IV™ is designed specifically for use in the discharging zone on the outside of a conductive casing, with anodes and Loresco SC-3® inside the casing. By placing EnviroCoke IV™ around the casing on the outside, a conductive seal is formed which serves as an environmental precaution against interchange flow between water bearing formations in the discharging zones. When used in conjunction with PermaPlug, total environmental control can be established.

EnviroCoke IV™, with its conductivity and ease of installation, provides a solution to environmental concerns pertaining to deep anode installations in sensitive areas.
