Drilling masts

We carry drilling masts in various sizes and designs that are manufactured by a Swedish company. This manufacturer is able to accommodate customers requests and due to many years of experience, produces very robust and reliable equipment (drilling masts are very popular in Sweden).

For blast holes, rotary drilling and pilling

Size: for excavators from 4 – 36 tons

Air- and water powered DTH hammer

Various designs and sizes (from 2”  to 30”) by Atlas Copco, Bulroc, Mincon and WAI.

Over the past years, I have had very good experiences with the water-driven hammer from WAI, as they have many advantages over the air hammer.

Firstly, the ground is not as affected by the escaping water because in comparison to air, water cannot be compressed and does not cause extensive washouts when outflowing.

Furthermore, the hole is cleaned by the water and doesn’t require cleaning after drilling (e.g. for grout curtains).

It doesn’t create dust, which is a particular advantage in tunnels and underground areas. Drilling in water - bearing mountains is easily possible. 

Another key advantage is the higher drilling performance, especially the deeper the boreholes are.

Last but not least, a major cost benefit is the operation of the hammer with a high pressure water pump, because they save over 80% of energy in comparison to a diesel compressor. 


Various layouts with different plug - in sockets including drill pipes and bits

Range of performance from 3300 – 33700 Nm

Rotary drilling systems/ jet grouting systems

Complete systems with rotary head, rotary head/ down the hole hammer combinations and double head for different applications.

Furthermore, complete equipment for 1-phase, 2-phase and 3-phase jet grouting as well as auger drilling and pile driving.

Roller bits

All sizes and types according to the IADC Code, short delivery times.

Innovation: roller bits with exchangeable roller elements.

Complete solutions for ground freezing, pipe umbrellas and anchor systems

Drilling systems, casings, drill rods etc. adapted to the respective parameters.

Equipment for steered (directional) drilling

We offer of the drilling tools as mud motors, jet plate/ slant - bits, rock drilling tools, stabilizers, x- overs etc., as well as the necessary measuring and control technology (measurement probes, steering systems, MWD – systems) and experienced experts/ operators.

The surveying technology is based on magnetic systems and different kinds of gyroscopes.

Basically, the magnetic systems are based on the detection of an electromagnetic field, which can give the actual position of the borehole as a xyz – coordinate.

Different setups of the systems are feasible in order to the respective application.

With our partner we can offer you the full package for steered drilling in soft and hard ground.

I have gathered a lot of experiences with directional drilling over the last six years and would like to see an increased application of these processes in building tunnels and ground engineering.
