Our solutions

Microtunnelling is a pipe jacking solution available for the trenchless construction of underground networks. This technique is suitable for wastewater and drinking water systems as well as for energy and telecommunications networks. Diameters handled go from Ø 500mm to 2,500mm without any real limit on lengths, since several sections, straight or curved, with or without slope, can be joined together.

The microtunneller’s cutting wheel is adapted to the nature of the ground encountered on a case by case basis. The excavated material from the pipe jacking is brought to the surface by hydraulic spoil removal and treated on-site prior to land-fill. The guidance system can be by laser or gyroscope.

The microtunneller/pipeline unit is jacked forward in stages. The unit length of the pipes is generally 3 metres.

SADE Serbia is able to propose this solution to its clients when it is necessary to realise trenchless works.

In addition to its expertise in tank lining and working with water-resistant concrete, SADE Serbia also specialises in sealing structures with geo-synthetic products or with the hydroclick® process. These solutions apply to landfill sites, basins, reservoirs and any other structure where isolation from the natural environment is made necessary as a protective precaution or because of regulations. They apply to both new works and those to be rehabilitated.

As an innovative international contractor that is fully committed to sustainable development, SADE Serbia offers a whole range of fixed or mobile solutions for recycling excavated material.
