Drilling

Vertical drilling used, inter alia, for installation of heat pumps



Sheet pile walls

Objects of economic activity includes performing works related to securing deep excavations by walling of steel sheet piles mostly by available type series and by means of bored piling and jet-grounding columns.



Microtunneling, HDD, jacking, drilling

do średnicy Ø3000 mm



Piles

FDP, CFA, WIPS, RIC



Jet-grouting

Jet grouting is a moulding technology on a soil-cement column ground that uses effect of cutting and grinding the ground under the influence of cement grout under high pressure.



Micropiles, soil nails and tie-back anchors

This technology consists in making hole in one process line, the introduction of injection grout and the reinforcement.



Relining

Relining is a trenchless technology used by repairing the existing underground infrastructure such as gravity and pressure pipelines.
