MITBOND HIGH DRILLING

MITBOND HIGH DRILLING, is a natural sodium bentonite that like the bentonite originating in Wyoming, USA. Having a very high colloidal activity and a very stable behavior in all the suggested uses.
MITBOND HIGH, is specially designed for assuring the best performances in the production of drilling fluids for piles, diaphragm walls, low permeability cut-off walls and its is successfully used in all the application where the pipe jacking technique is employed. Especially Micro Tunneling & HDD ( Horizontal Direction Drilling).

MITBOND HIGH, is particularly suitable for all soil sealing purpose as waste disposal sites bottoms and slopes, roads and railway underneath layers and polluted areas, rehabilitation.

MITBOND HIGH, may also be successfully used in water drilling as it meets and exceed the OCMA specification.
