LPI EARTH ENHANCING COMPOUNDS
Due to varying soil conditions from one site to the next, the installation of earth electrodes alone can often fall short of achieving a low resistance earthing system.
The application of earth enhancing compounds (EECs) around earth electrodes makes a significant impact towards achieving the low resistance required for an effective earthing system. They achieve this goal without the expansion and shrinking characteristics of some cheap alternatives that can effectively render the earthing system useless over time.
| Characteristic | RESLO-20 | Comment |
| Ingredients | Sodium bentonite, gypsum, special additive | RESLO – natural, benign components SRIM-PLUS – natural and recycled components |
| Packaging | LDPE-lined woven polypropylene bag | Environmentally friendly, recyclable packaging |
| Shelf Life (years) | > 1 | Shelf life is longer than 1 year if kept in a dry environment |
| Bag Size (kg) | 20 | User-friendly and efficient quantity |
| Resistivity (Wm) | ~ 0.53 | SRIM is at least 5 times more conductive than RESLO due to its special high-tech formulation |
| Typical Resistance Reduction |
> 50% | Temporal / seasonal variability is also greatly decreased |
| Typical Amount Required |
5 x 0.3 m trench: 1 bag 0.125 x 1.8 m hole: 1 bag |
Or use the LPI Earthing Calculator for more accurate estimates |
| Leaching | Negligible (but not for use around water tables) | Leaching is well below EN and EPA limits or is undetectable |
| Sulphur Content | > 2% (from natural ingredients) | All clays and gypsum have natural sulphur, which is generally benign |
| Corrosion Performance | Greatly exceeds IEC 62561-7 requirements |
SRIM PLUS is specially formulated to be non-corrosive despite its high conductivity |
| Hardening | Semi-hardens within 3-5 days | Hardening / curing time depends on environmental conditions |
| Maintenance Required | Nil | Permanent encasement of electrodes if installed per LPI instructions supplied |
| Service Life (years) | > 15 | Long lasting enhancement if installed per LPI instructions |
| Standards Compliance | AS 2239, IEC 62561-7*, EPA 1311 | * RESLO is only “non-compliant” with regard to sulphur content |
