TerraFill® Ground-Enhancing Backfill
TerraFill® low-resistivity grounding backfill offers a simple, highly effective method to substantially lower the earth resistance of grounding systems. When paired with copper grounding equipment, contact resistance to the earth is reduced by up to 63%.
By creating a reliable, low-resistance electrical connection, TerraFill® produces lower steady-state ground impedance and a stable connection to the earth. Additionally, Alltec’s formula delivers lower surge impedance, resulting in faster transient dissipation. Manufactured from environmentally safe, stable materials, TerraFill® boasts an excellent shelf life and long-term storage capability with zero degradation in performance.
Easy to apply using standard field installation methods
Excellent shelf life and stable long-term performance
Will not dissolve, wash away, or decay over time
Completely maintenance-free once installed
Maintains consistent resistance for the entire lifespan of the grounding system
TerraFill® Applications
TerraFill® creates a highly reliable, low-resistance electrical connection between your grounding system and the earth. It is fully compatible with copper grounding grids and standard installation methods, making it ideal for minimizing dangerous step and touch potentials.
Installation Guide: Locate the number 2 on the application maps to the right to view typical installation locations.
How It Works
System Compatibility: Specially formulated to be compatible with copper grounding systems and standard field application methods.
Safety-Focused: Can be used in conjunction with grounding grids to successfully minimize step-and-touch potentials.
Design Versatility: Applying TerraFill® to lower ground resistance allows engineers to implement creative, highly effective earthing designs that might otherwise be impractical due to space constraints.
Self-Compacting & Easy to Handle: Shipped in easily transportable 50 lb (22.68 kg) bags. The self-compacting formula is designed to be easily installed by a single person.
High Performance: Consistently produces acceptable grounding impedance even in high-resistivity soils within a reasonably sized footprint.
