Conductive Carbon Backfills
Exceptional Backfill Quality & Purity
Their carbon backfills start with high-quality carbons calcined under ISO 9001:2015 standards at a minimum of 1250 °C, resulting in very low volatiles, low ash, and high fixed carbon content (over 99%).
High-Conductivity Performance
Features such as surface-modified particles, high bulk density (up to 74 lb/ft³), and low resistivity ensure maximum electronic current transfer, extending ground bed life and reducing operational costs.
Easy & Flexible Installation
Products like SC‑2® mix well with water and settle on their own, no vibrating or compacting needed. RS‑3® combines pumping and pouring adaptability, with rapid sinking to support quicker system energizing.
Versatile Deep Anode Solutions
The Replaceable Deep Anode System enables anode replacements without drilling new boreholes and offers superior system reliability even in constrained or high-resistivity environments.
Simplified Maintenance & System Longevity
Deep anode systems are designed for easy inspection, replacement, or repair quick, cost-effective maintenance that minimizes downtime.
Safe & Compliant Solutions
Loresco PowerFill™ grounding backfill is NSF/ANSI‑60 certified for use around potable water systems, contains no hazardous substances, won’t leach into the ground, and includes corrosion inhibitors, making it safe and sustainable.
Strong Worldwide Track Record
Loresco is globally recognized for superior conductive carbon backfills, trusted across sectors from pipelines and storage tanks to power generation and communications infrastructure.
Engineered Solutions for High-Demand
Advanced products like RS‑3® and SC‑2® are engineered for high-current, deep installations with superior conductivity and rapid settling, yet responsibly packaged and easy to handle.
