One of the core business Gidrokor Construction Company Ltd. areas involves the application of advanced waterproofing technology in industrial, hydro and civil construction.
Both as a subcontractor (impervious insulating membranes, reinforcement of construction elements and equipment) and general contractor (residential and industrial-waste landfills), GIDROKOR conducts design and construction work on the following types of sites:

  • solid residential-waste (SHW) landfills, storage facilities for industrial waste with various hazardous-material classifications (solid and liquid), sludge reservoirs, ash dumps, and heap-leach pads, etc. in the petrochemical, metallurgic, mining, and pulp-and-paper industries, as well as at thermal power plant (TPP) facilities;
  • crude oil and refined petroleum-product tank batteries, gas stations (GS);
  • earthen barriers (dams, dykes), artificial reservoirs, including those integrated into industrial complexes;
  • irrigation and drainage facilities (irrigation canals, water reservoirs);
  • waste ponds for agro-industrial enterprises: agricultural farms, livestock farms, food-processing facilities (manure ponds, plant-waste compost facilities).

For the past 16 years, as a member of such international professional associations as the International Geosynthetics Society (IGS) and the International Association of Geosynthetics Installers (IAGI), GIDROKOR has been successfully implementing in its design and construction work the application of geomembrane – rolled polymer sheets varying in thickness from 1.0 mm to 3.0 mm made of high-density (HDPE) and low-density (LDPE) polyethylene. 

Today’s HDPE and LDPE geomembranes are produced with smooth and textured surfaces, and are known for their advanced waterproofing and anti-corrosion properties. They also have superior stress-strain properties. A prime example of this advantage is that upon contact with liquids, only diffusion at the molecular level becomes an issue. Geomembranes stand out for their superior stability over the majority of other chemical agents (рН between 0.5 and 14). They are flexible, shrink-resistant, and crack- and damage-resistant (tensile elongation under maximum load of up to 850%, high tensile strength of up to 26.2 MPa). UV resistance and resistance to temperature changes, combined with high puncture- and seismic-resistance properties, ensure the widest-possible practical application of polyethylene geomembranes in all climactic zones. When professionally installed, geomembrane structures have an operational lifespan of at least 90 years.

In 1996, GIDROKOR became the first company on the Russian market to introduce the practical use of polymer geomembranes in the design and construction of environmental-protection facilities.

When attempting to ensure the reliable containment of potential environmental-pollution sources, the primary concern is ensuring the effective insulation of groundwater, soil and air from toxic contamination.

This challenge can be effectively addressed by creating a filter-proof protective membrane. While there may be different approaches to designing such impervious membranes, one thing can be said for sure: many modern engineering solutions simply could not be implemented without the use of geosynthetic materials. Whatever the specifics of the project at hand, the prudent and well-engineered application of geosynthetics always results in a comprehensive techno-economic effect in terms of environmental protection.

The use of geosynthetics in construction has dramatically altered the nature of work involving hydro and tunnel construction and the commissioning of underground structures and facilities:

- their functional specifications (protection, filtration, drainage, reinforcement, separation, isolation) have a significant impact on a wide range of practical-application areas;

- their high technological effectiveness results in significant reductions in the scope of excavation and concrete work, and thus in overall construction time;

- the stress-strain properties of the material meet the reliability and durability requirements of structures and installations; 

- the combination of technical specifications and critical performance properties allow for a certain universality of application, often yielding the only possible engineering solution;

- the well-developed method of evaluating the quality of related materials and work (on the basis of international standards) is another of the critical advantages provided by geosynthetics, inspiring confidence in the professional manner in which work with these types of materials is conducted;

- the logistics support provided when working with such materials has a dramatically-positive impact on popular attitudes towards them;

- another important factor is that using geosynthetic materials minimizes the negative impact of construction on the environment, insofar as they are manufactured from physically- and chemically-inert (i.e. environmentally-friendly) polymers;

- economic effects, or, to be more precise, cumulative economic effects, underlie all of the aforementioned aspects of geosynthetic use.

Based on GIDROKOR’s many years of professional experience, it can be asserted that the superior reliability of structures made with geosynthetics, minimum geomembrane-installation times, and the well-developed method of evaluating the quality of related materials and work, clearly demonstrate the technical superiority of geosynthetics and the expediency of its practical use.
