Bailers and auger-bailers

The bailer consists of a stainless steel cylinder with a bailer head at the bottom . In the bailer head a stainless steel or synthetic valve is mounted that can only open into the bailer tube. The stainless steel valve responds with more precision during bailing than the synthetic valve, which is more flexible to fine gravel. The valve has a 45º opening. The bailer’s diameter is agreed with customer to allow optimal movement in the tube.

The top end of the bailer has a thread connection, to which extension rods can be attached.

Bailing rests on the principle of up-and-down movements of the bailer, stirring the water in the borehole,

thereby suspending the soil material. As the valve opens on downward movements and closes when the bailer

is hoisted, the suspended soil material is trapped in the bailer.
