All LECTRO-TECH earth mats have LECTROWELD exothermically welded joints.
CONDUCTIVE EARTHING COMPOUND (CONCRETE)
Two different compounds are available, both are an easy to use compound that:
- reduces soil resistivity,
- improves earth electrode contact with soil,
- improves grounding earth resistance,
- traps moisture,
- will not leach out over time.
E-Mix and E-Mix Super Conductive have been tested by independent authorities.
-E-MIX (Resistivity ρ:- 559Ω.cm)
Tested to IEC 62561-7
Cement included, ready to mix with water
Size: 25kg | Code: E-175
- E-MIX SUPER CONDUCTIVE (Resistivity ρ:- 29Ω.cm)
Tested to IEC 62561-7
Cement included, ready to mix with water
Size: 25kg | Code: E-172
EARTH RESISTANCE CALCULATOR:
Contact us for a copy of our
"E-Mix Earth Resistance Calculator"
- for single vertical rod
- for trench earth
CALCULATES:
- resistance "with" and "with-out" E-Mix
- number of bags of E-Mix required
USER INSTRUCTIONS
Mix the cement supplied in the bag with the E-Mix compound, then mix with water to give a slurry consistency
Drilled hole-(70-100mm dia):
Fill hole to approx. 50% of depth with E-Mix.
Place earth rod in centre of hole.
Fill the rest of the hole with E-Mix.
Agitate rod to remove air-pockets.
Trench-(250-300mm wide):
Add half the depth (25-30mm) of E-Mix to trench and
allow to set so that earth conductor is supported.
Place earth conductor on top of E-Mix in trench and
add a further 25-30mm of E-Mix.
Allow E-Mix to semi-harden (24 hours depending on
temperature) before backfilling trench.
Compact backfill 48 hours later.
