Abstract: The article presents data on physical and chemical properties and data on the use of geomembrane waterproofing polymer roll. The above material is made on the basis of high-density polyethylene using carbon black, antioxidant and high temperature stabilizer. Geomembrane is used in many areas of production, including waterproofing manure storage. As a contacting medium with the studied material comes from the native liquid manure of cattle and pigs (humidity up to 92 %). Samples of material and manure were placed in the desiccator in a ratio of 2 : 1 cm3/cm2, followed by their content in a thermostat at a temperature of 20 + 1 °C and 60 + 2 °C. The duration of material contact with manure (exposure) was 10, 20 and 30 days. At the end of these terms, the content of the desiccators was used to produce a heavy filtrate, where the content of formaldehyde, lead, cadmium and zinc was determined. Geomembrane releases lead, zinc, and cadmium in contact with native litter-free cattle and pig manure. The level of their content in manure was: lead ‒ 0.003‒0.012; zinc ‒ 0.003‒0.009 and cadmium ‒ 0.001‒0.003 mg/l. The level of lead, cadmium and zinc release from the geomembrane does not exceed the maximum permissible concentrations in soil, animal feed and food. The emission of formaldehyde from polymeric geomembranes in the manure is not installed. In addition, the level of their isolation is also significantly lower than the maximum permissible levels (MDU) in feed for farm animals. Based on the obtained results, geomembrane can be used as an anti-filtration coating for storage ponds and manure storage facilities at pig farms and cattle farms.
