The spectrum of our activities extends from renovations to the construction of new urban roads, field roads, parking and paved areas.

760/5000 In 2000, our company was the first in the Czech Republic to equip itself with a computer-controlled synchronous system ENERPAC, designed for even and controlled lifting and lowering of heavy loads. Synchronization is performed by the computer automatically, based on the monitored lift stroke data and the weight distribution on the individual hydraulic cylinders. Thanks to this system, considerable time savings can be achieved during the handling of the supporting structure, while maintaining high accuracy within the load lifting tolerance (up to 1 mm). Unwanted additional stresses are not introduced into the lifted structures and the entire handling becomes considerably safer. A protocol is obtained from the elevation / lowering sequence where the stroke stroke data and the pushing force of the hydraulic cylinders are stored at selected intervals.

The work was carried out in two stages, successively for each of these two tracks, consisting of: demolition of the stone railing, ledges and existing track, as well as the reinforced concrete slab of the new ballast trough, epoxy polyurethane insulation of 5.656 m2. railing, installation of HDPE drainage in the length of 475.50 m, cleaning and local repair of concrete and stone parts, hydrophobization and anti-graffiti coating of the supporting structure on a total area of “‹“‹21,578.00 m2. In addition, specialized stone work was carried out on decorative stone elements worth PLN 975,350 incl. VAT, reinforcement of the slope cone by the stone pavement on an area of “‹“‹540.00 m2 and reinforcement with a heavy stone on the banks of the Nysa Łużycka River in the volume of 650 m
