For the protection of rock slopes along existing roads and along roads under construction with regard to geotechnical conditions, the following is used:

Rehabilitation of tunnels from leachate and rock falls includes:

There are several factors that cause landslides. First, these are clay sediments in the composition of the terrain in which the slopes are formed. As a rule, the larger the clay layer, the greater the possibilities for landslide development, especially if the permeable layer on the slope is thinner.

Another factor is the alteration of permeable sandy and impermeable clay layers on the slope. An important factor is the increase in the amount of water and hydrostatic pressure in the sediments. Namely, sliding surfaces are always bonded to clay waterproof layers. Clay binds water to itself, swelling and multiplying its volume. This results in pressures that destabilize the permeable layers above the clay layers, which then begin to slide down the slope.

During the landslide rehabilitation works, the presence of experts is required to review the performed works, to consult the contractor and the supervising engineer, and for possible minor changes in the project documentation, according to the actual conditions on site.

The following is used for landslide rehabilitation:

Rehabilitation and construction of roads, maintenance and protection of highways, bridges, railways, overpasses, tunnels and other traffic facilities. It also includes preparatory works in construction, such as: excavations, embankments, levelling of the terrain, excavation of canals, removal of rocks and alike.

Regular maintenance includes activities that are continuously undertaken on the roads, in order to ensure the greatest possible degree of safety, adequate speed and comfort of road traffic. This maintenance of roads and traffic safety is the basis of our business.

Activities include road maintenance, maintenance of drainage, kerbs and slopes, and maintenance of facilities along roads. Here we use:
