The requirement for a low resistance is extremely important with the installation of any earthing system. LYTECH EEM provides the ability to dramatically reduce soil resistivity even in soils with average electrical conductivity.

 

EEM comprises specifically selected compounds, which possess excellent electrical conductivity. When EEM is mixed with water and poured around the earthing system and surrounding soil the powder and water react to form a hardened mass within an earthing system. EEM will not wash away under seasonal conditions and therefore provides a permanent presence in working to improve and maintain the integrity of an earthing system. Given that does not wash away the requirement to re-treat the soil as is the case with other enhancing compounds is eliminated.

 

EEM is supplied in multiples of 10kg-packaged bags to suit the site application. These packaged bags have full installation and handling instructions and combine a plastic handle and HDPE plastic liner for easy and safety of handling. 

 

 

Product Application

 

Given that all earthing systems are installed in varying soil types and conditions, it will be appreciated that the application results of EEM will also be dependant on these site-specific conditions. For a typical trench installation, one 10 Kg kit of EMM will achieve the desired earth resistance levels in combination with appropriate conductors for a trench covering 2.5m in length x 300mm in width and a depth of 500mm to 1000mm.

 

All earthing systems are typically required to achieve a Ground DC Resistance of < 10 Ohms and impedance of < 30 Ohms as outlined in most standards.

 

If installing either a radial earthing system or grid type earthing system it is recommended that all earthing conductors be installed at a depth of between 500mm and 750mm (recommended) with a maximum depth of 1000mm. In order to further assist in improving the earth resistance of the system, it is recommended that excavated soil of poor quality (Rocky) be replaced with soil of a good quality (Garden Loam) prior to back-filling the trench.
