Petroleum backfill for boreholes
Réf. DIP-133
Special borehole petroleum coke backfill (2-5 mm grading), density close to 1 for easy placement below the water table. Very low resistivity (<50 Ω·cm), packed in 1 t.
Description
This petroleum backfill offers high performance for borehole installation: its density close to unity eases placement (it does not get stuck at the water table), and its very low resistivity keeps the resistance constant after the borehole tube corrodes.
Specifications: 2-5 mm grading, density ~1 kg/l, moisture 0.2%, carbon content ~88-89%, ash ~8.3%, sulphur 1.2%, resistivity <50 Ω·cm (standard A05-252). It stands out with a low bulk density, low resistivity, high porosity, good flow and low sulphur content. It is supplied in crates of 40 bags of 25 kg (1 tonne) or, on request, in a 1 t big-bag.
