In order to avoid urban blockages caused by surface works for the installation and rehabilitation of underground pipelines for public utilities, trenchless technologies are often used, which allow the works to be carried out without the need to excavate ditches.

Trenchless technologies are the optimal solution for crossing roads and other transport corridors, as well as rivers and waterways.



Auger boring can be defined as a method of boring beneath the earth’s surface by means of a jack and a bore. It works by simultaneously jacking the casing pipe while the rotating augers remove the excavated soil.

The auger machine can be installed using a steel sheet pile sending and receiving pit and also use sheet piles for manholes.

Auger boring is also known as dry boring because unlike other methods of boring, no slurry is generated.

During auger boring, a cutting head with a slightly larger diameter than the casing pipe excavates the soil just in front of the casing. The helical rotating auger blades carry the soil back to the machine where it is removed either by hand or machine. The auger boring machine runs along a track which is aligned with the casing pipe where it has to be installed.

Auger boring is cost-effective and less time-consuming. A good understanding of soil conditions where auger boring is to be carried out is essential while designing these projects, so geotechnical reports and investigations are indispensable.



Dewatering & Silent Piling offers a set of solutions for the rapid and efficient construction of dams and cofferdams. We offer free of charge support from the design phase for permanent sheet pile structures, both steel and synthetic.
Metal sheet piles can be used in a wide range of flood protection or shore protection systems. In the construction of new dams, metal sheet piles can ensure their tightness, stability and support.
We offer design, execution and rehabilitation solutions for port structures for carrying out port loading and unloading operations in and from river / sea vessels, in conditions of safety and economic efficiency. The construction of mooring fronts is done by installing docks based on piles or columns.
Our solutions for dredging: dredging pump and dragline. Dredging pumps can be attached to an amphibious excavator, using its hydraulic motor, or they can be used with separate power unit and mounted in the crane hook.
They are made of PVC (polyvinyl chloride or composite material). They represent an alternative solution to steel sheet piles, concrete dikes, gabions or boulders in various hydrotechnical projects and more.
