What SealEco does

SealEco is a Swedish-founded manufacturer of EPDM (Ethylene Propylene Diene Monomer) rubber waterproofing membranes, operating as a specialty brand within the Nordic Waterproofing Group. The company organizes its offering into three product families: roofing membranes (Prelasti, Topskin, EVALASTIC, EcoStar, One-Tool-Roof) for flat and low-slope roofs; facade sealing systems (CladSeal, RubberShell, AlphaFlex) for window profiles, DPC and cavity trays; and lining/geomembrane products (ElastoSeal, Topskin Pondliner) for water reservoirs, biogas plants, ponds and industrial containment. Core proprietary capabilities include Thermobond induction fastening (a non-penetrating mechanical bonding method), 3D prefabrication of membranes to centimetre-level tolerances, and tailor-made roll-out delivery for self-installer and contractor use.

The business model is predominantly B2B project-based hardware sales with custom quote-based pricing, supplemented by channel revenue through an extensive distributor and prefabricator network. SealEco runs direct sales offices in Sweden, the Netherlands, Poland, Belgium, Switzerland and the United Kingdom, while a global dealer network of 20+ regional partners extends coverage across Europe and into the Middle East. End-customers span roofing contractors and installers, architects (served through specification platforms such as TotaalDakConcept), industrial operators, water authorities, municipalities and landscape professionals. SealEco's Dutch subsidiary (SealEco BV) was acquired by Kingspan's Roofing + Waterproofing division in late 2024, while the parent Swedish entity remains within the Nordic Waterproofing Group, which reports turnover exceeding EUR 300 million and approximately 1,200 professionals across the broader group.

SealEco holds ISO 9001 and ISO 14001 certifications, and has published Environmental Product Declarations for several product lines under ISO 14025 and EN 15804. Independent laboratories (Constructech Sweden AB, SKZ Germany) have verified product lifespans of 47+ years proven and 70 years expected. The company is not listed, has no disclosed funding rounds, and competes in a market where product longevity, EPD compliance and certified installation networks function as primary differentiators.

Products include the Prelasti, Topskin, EVALASTIC, EcoStar, CladSeal, RubberShell, AlphaFlex, and ElastoSeal lines, with 2D and 3D prefabrication customized to the centimeter. The company also offers the One-Tool-Roof DIY system enabling screwdriver-only installation across commercial, industrial, residential, and modular buildings.

Product overview

SealEco is a manufacturer and complete supplier of tailor-made EPDM (ethylene propylene diene monomer) rubber waterproofing solutions, organized into three core product lines: roofing solutions (covering flat, low-slope, pitched, and green roofs), facade solutions (for moisture and airtight sealing), and lining solutions (for water reservoirs, ponds, geosystems, and biogas applications). The core roofing products include Prelasti EPDM (available in S, FR, and Fleece variants for ballasted, adhered, and mechanically fastened systems), Topskin EPDM, EVALASTIC EPDM (in black, grey, and white variants including EVALASTIC White), EcoStar EPDM slate, One-Tool-Roof (a DIY system requiring only a screwdriver), and AluShell vapor barrier. Facade solutions include CladSeal EPDM (complete facade sealing system), RubberShell EPDM (glass-fibre reinforced self-adhesive membrane), and AlphaFlex EPDM (lead substitute available in Basic and Wave variants). Lining solutions include ElastoSeal EPDM (geomembranes for basins, reservoirs, biogas, and industrial applications), Topskin EPDM Pondliner (for ponds and water features), and custom 3D prefabricated EPDM for plant boxes. The company operates as part of the Nordic Waterproofing Group and has manufactured EPDM products in Sweden since 1967, with operations in the Netherlands (SealEco BV), Poland, Belgium, Germany, and Sweden. Products are certified with ISO 9001 and ISO 14001, and carry Environmental Product Declarations (EPDs).
