Installation

Over a period of 6 years our company provides professional geomembranes installation services as a waterproof screens.

One of the most important features of geomembranes is the fact that the reliability of the structures installed using geomembranes is provided not only by characteristics of the material itself, but first and foremost by the quality of assembly, i.e. quality of geomembrane sheets welding into a continuous watertight screen. Considering that the watertight screen is an important structural unit of any facility only certified specialists should execute its installation.

It should be noted that the material quality and professional installation does not guarantee the reliability and efficiency of the finished facility. The key determining factor is the feasibility of projects design. It is reasonably to consider geomembranes not just as a material, but as a technology.

First polymer materials were applied in construction in Huntley (Montana, USA) in 1953 for watertight screen of 1.0 ha area irrigation pond. ​​ At that time it was a polyethylene film with thickness of 0,4 mm. From that moment the number of projects using polymeric materials, integrated into general term “geosynthetics”, increase every year worldwide.

Among the first local facilities using the geosynthetic materials was the wastewater pond of zero-discharge water system of the Krasnoyarsk Aluminium Plant developed by “Gidrokor” company (Saint Petersburg) in 1996. For installation of the waterproof screen 1.0 mm-thick, high-density polyethylene (HDPE) geomembrane manufactured by NSC (USA) and an imported geotextile fabric with a density of 300g/m² were used.

The use of geosynthetics in Kazakhstan is a customization of European technologies. Specialists of Gidrokor at the same time with the active promotion of geosynthetic materials and technologies in Kazakhstan newly developed the “Guidelines for the design and construction of impervious screens using polymer geomembrane” together with the B.E Vedeneev All-Russia Research Institute and K.D. Pamfilov St. Petersburg Research Institute of the Academy of Public Economy in 1997. The document passed two re-editions and still valid.

Existing SN-551-82 “Instructions for design and construction of impermeable polyethylene liners for artificial water bodies” does not conform to modern polyethylene geomembranes properties.
