Sealeco EPDM membranes - advanced waterproofing technology

16 of February '26

As the largest manufacturer of EPDM flexible membranes in Europe, SealEco offers access to extensive waterproofing expertise. The headquarters and production facility for EPDM membranes is located in Värnamo, Sweden. In Poland, the company operates under the name Nordic Waterproofing Sp. z o.o.

SealEco EPDM membranes are laid as single-layer waterproofing. The most important features of EPDM membranes are their flexibility and extensibility of more than 300%, total resistance to UV rays and a very wide range of application temperatures, from - 35˚C to 130˚C. They can therefore be laid and left as a layer exposed to outdoor conditions. The confirmed durability of this material is a minimum of 50 years. It fits almost any substrate, is resistant to mechanical and chemical damage, and performs well in all climatic conditions. EPDM membranes do not require any servicing and maintenance, remain permanently flexible and are resistant to harmful external factors. They can be mechanically fastened, glued or ballasted. In Sealeco technology, the joining of membrane elements is carried out by hot vulcanization, with the possibility of prefabricating to individual size flat and spatial shapes, to be laid out on site. An important advantage is that they can be laid at low temperatures.

Our offer includes sealing solutions for flat roofs, terraces, balconies, tanks and facades. Flat roofs are divided into exposed, that is, where the waterproofing membrane is the last and exposed layer of the roof, and ballasted, where the waterproofing is hidden under the finishing (ballast) layer. Terraces can be finished (ballasted) with, for example, gravel, pavers, exotic wood, composite flooring, greenery or other materials depending on the needs and imagination of the investor. Similarly, balconies, after the EPDM waterproofing membrane is laid, can be finished with flooring on footers or joists. For this type of project, we offer EPDM Prelasti/Prelasti Fleece membranes and provide system solutions for sections and details, taking into account such requirements as proper waterproofing, thermal insulation, drainage, rainwater drainage, payloads, and functioning of greenery.

SealEco EPDM membranes are applied in a single layer, in different thicknesses, depending on the type of building, method of attachment, etc. For roofs and terraces, we use 1.2 mm / 1.5 mm thick membranes (EPDM Prelasti) or a reinforced 2.3 mm thick membrane (EPDM Prelasti Fleece).

In most cases, we try to deliver the membrane to the site in the form of a prefabricated product or prefabricated products, prepared in the required dimensions on our production floor. These are simply laid out on site, which significantly reduces installation time. The prefabricated elements must be joined together and any necessary detailing of the roof or water tank must be done. The quality of the welds made by us (hot vulcanization) ensures 100% waterproofing of the membrane. If due to the layout of the roof the use of prefabricated is not optimal, we suggest laying the EPDM membrane directly from the rolls.

For a correct and binding quotation of the material cost of EPDM membrane roofing, basic design documentation (roof plan, sections) is necessary. After receiving it, we take the measurement of the range of materials and present a comprehensive offer for waterproofing a given building with EPDM Sealeco technology. We also assist roofing contractors with the necessary equipment and technology for the installation of EPDM membranes, during the actual roofing work on the object.

If necessary, we also assist roofing contractors with the necessary equipment and EPDM membrane installation technology, during actual roofing work on the site. Independently, we periodically organize theoretical and practical training courses for roofing contractors who want to acquire new skills in the installation of EPDM membranes using SealEco technology.

We invite you to cooperate with us.
