Self operation training available

In operation

• Uses water as medium to agitate ground
• Uses water pump on machine
• Does not create dust cloud when digging
• Spoil suitable for backfill when SMA added (Please contact for further information)
• Reduction in number of barriers used
• Handles clay with ease
• Water acts as its own lubricant
• Water controls static electricity
• Damage to area surrounding the excavation zone is minimised
• Water can be heated for frozen ground excavation
• Water works in almost all soil conditions
• Water prevents the sandblasting effect of air
• Water is far more productive, especially in tough soils
