Our goal is to improve environments by sediment treatment, restoring the capacity of reservoirs, deepening and maintaining waterways, shipping channels and cleaning out lakes and ponds.


  • Natural water environment: Sediments in the hydrographic system I.

    We define sediments as solid mineral materials such as gravel, sand and also as particles of biological material – the remains of fallen leaves. The dynamics of sediments consists of three processes: creation, or entry of sediments into the environment, movement, and deposition of sediments. Sediments enter the aquatic environment most often due to erosion.

  • The natural environment of watercourses

    Vegetation growing along watercourses plays a major role in the country. It is a habitat that provides animals with food, safe shelter, and for many species with breeding potential. In addition to these functions by connecting several different natural habitats, it acts as a bio corridor through which organisms migrate. Among other things, they have

  • Geotextile tubes

    We usually approach the processing of sediments if the conditions for the creation of sedimentation areas-lagoons are not suitable in the area of ​​the implementation of the contract. Due to insufficient free space or due to high groundwater levels. Sediment dewatering is also performed in case it is necessary to remove sediment from the project

  • Dredging without draining

    The removal of sediment from the bottom of the lake in the traditional way requires drainage of the water in the lake and subsequent implementation of construction machinery at the bottom of this area, which must be dried to a driveable state. The process of draining the tank and then drying the sediment in situ
