Terec+ is chemical earth enhancing compound that adheres to IEEE 80:2000 clause 14.5(d). It has a shelf life up to 24 years. It is best used in high soil resistivity areas which typically varies from season to season.

Product Features

  • Improves electrical conductivity of soil
  • Eco friendly
  • Least corrosion
  • Non-leaching
  • Maintenance Free
  • Soil Resistivity value have a seasonal variation of ± 10%

Salient Features

  • Ionic compound: Creates ions for easy conduction
  • Dispersion compound: Spreads the ions equally in the earth pit
  • Expansion compound: Expands 18 to 20 times and removes entrapped air to create a strong connection between rod and soil.
  • Diffusion compound: Diffuses into soil pores and creates conductive silicone roots enlarging conductive zone of earth pit.
  • Hygroscopic compound: Absorbs atmospheric & surrounding moisture and retain it in the soil
