Process water tanks

• EPDM is a synthetic rubber (rubber) belonging to the group of elastomers. It is a homogeneous, chemically stable material that does not contain plasticizers - substances that cause elasticity, for example, PVC film membranes, which migrate, leach and evaporate over time, adversely changing the properties of these materials, causing them to stiffen, which can lead to leaks.
• The flexibility of EPDM membranes, which is very important in tank insulation, is due solely to their specific molecular structure. Thanks to it, we do not observe stiffening of the EPDM membrane over the years.
• EPDM is a chemically dead material, that is, after vulcanization, no chemical processes take place in it that change its properties.
• No components escape from it into the environment, this is confirmed by the certificate of neutrality for the water environment and PZH approval for use in drinking water tanks.
• The EPDM membrane is thermostable and retains its flexibility and strength over a wide temperature range, i.e. from - 40ºC to + 120ºC, among other things, so it is possible and safe to install the membrane even at very low temperatures.
• Thanks to its chemical homogeneity, the EPDM membrane is much more resistant to atmospheric aging (EPDM is resistant to ozone, UV radiation, most aggressive chemicals and microorganisms, among other things) than other commonly used waterproofing materials.
• EPDM has so-called shape memory - the material returns to its original shape and dimension after stretching up to 300%.

The EPDM membrane is prepared under production conditions. Prefabrication in advance allows constant control over the parameters of the material and the welding of the elements. Maintaining proper prefabrication parameters affects the quality of the final product. The membrane undergoes detailed quality control before packaging and arrives at the construction site as a ready-to-install component. Pre-prepared membrane significantly reduces the assembly time of the tank, allows installation even during severe frosts, increases the effectiveness of tightness tests eliminating all the problems that can occur during the execution of the membrane on the construction site.
