Also known as Horizontal Directinal Drilling ( HDD ) this technique is frequently used to drill accurate small bore tunnels to pass services, such as pipelines and cables, under difficult obstacles, such as rivers and major trunk roads.
Bentonite is used in various forms to seal boreholes.
Bentonite is used in Soil Remediation because of its principal properties:
The ability to form a waterprof seal
The ability to adsorb and bind certain contaminants
The ability to be pumped and placed over long distances
Zeolite is used because of its strong affinity for many contaminants, and its abiity to bind these for removal or filter them out of flowing water
