We at Stemba AG are experts in trenchless civil engineering and in particular in controlled flush drilling technology. We take care of all activities for our clients, from planning the borehole to testing the tightness of the inserted pipes, all from a single source. In addition to longer and more complex flush drilling under roads, railways, crossings, streams and cultivated land, our core competencies also include house connections using earth rockets and controlled pressing equipment.

Flush drilling is particularly suitable when conventional pipe laying is not possible or desirable due to the associated increased costs for the repair of roads and waterways, possible restrictions on road traffic, interference with nature conservation areas or extreme terrain conditions.

Flush drilling is always an alternative to conventional trenching, as flush drilling is generally faster, cleaner, safer and ideally also cheaper. The topsoil is not touched in a directional drilling operation, so there is no mixing of the different layers of soil. In the same way, the expensive pavement does not have to be damaged, disposed of and/or relaid and there are no unsightly pavement patches.

In addition, our flush bores are always measured using GPS and can therefore be easily entered in the local authority's utility plans, including the respective depth.

The company Stemba AG is active in the field of trenchless civil engineering. We are experts in controlled horizontal drilling technology and carry out undercrossings of roads, railways, crossings, streams, etc. on behalf of our customers, which cannot or may not be carried out using conventional trenching.
