Horizontal Directional Drilling Equipment
Depending on the specific project requirements, Codmah can offer Horizontal Directional Drilling (HDD) techniques to our clients.
Codmah has a range of HDD equipment which can cater for small tight access bores, mid sized bores and large diameter rock bores. The HDD fleet includes Vermeer 24x40, 36x50 and D100x120: all rigs include their own vacuum sucker truck and recycling units as required.
This is often the most feasible method when a pipeline must be laid where there are:
• Manmade structures i.e. under built up residential & commercial areas, roadways & or railway lines.
• Natural obstacles i.e. soft ground and or under streams / rivers.
Benefits of HDD over Open Cut methods include:
• Compact plant size allowing flexibility in very tight worksites (inc inner city)
• Small construction foot print i.e. drill entry exit point within 2sq mtr areas
• Quieter than excavator and or trencher operations
• Environmentally friendly technique – non toxic polymers & bentonite drill fluids
• Very high point to point accuracy
