What is overburden fill?

Overburden Soil is a general, unprocessed, fill material that can contain a variety of different materials, depending on where it is sourced. Overburden Soil can contain sand, rocks, clay and stones, and will typically lack the organic material and nutrients found in topsoil.

What is odex drilling?
ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing. Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground. Rapid removal of cuttings.
