Sealants
Self-healing membranes & swellable wet applied visco-elastic Polyisobutene systems.
Our Sealant Systems consists of a wide variety of 100% water-stopping systems. We can protect wall penetrations (for cables and ducts), concrete floors and basements, tunnels, dry docks, casings of pipelines through waterways, underground valve chambers for the sealing of groundwater, and harbour walls - safe, fast and secure. The sealants can also be combined with fireproof barrier and intumescent materials according to and in line with the local building regulations. The sealing systems are TNO tested and rodent proof. Also, there are attests of the German-T-COM and TNO.
Windows, Skylights, Glass Panes

Ushaka Marine World Rehab Centre Observation window
Polyisobutene, a visco-elastic material, offers a range of sealant solutions that are non-aging and non-curing. These long-lasting sealants are perfect for your windows, skylights, and glass panes. Their durability ensures a secure seal, maintaining the integrity and efficiency of your installations for an extended period. This makes them an excellent choice for both residential and commercial applications in comparison to older sealant technology and applications.
At the Ushaka Marine World Rehab Centre, a sealant solution was needed for the observation window. Previous attempts had been unsuccessful, and other sealants were deemed unsuitable due to potential risks to marine life. The ideal solution was found in the application of visco-elastic Polyisobutene. This material is not only FDA and NSP approved, but it’s also 100% environmentally friendly, non-toxic, and harmless, making it the perfect choice for this sensitive environment.

Leaks are identified and repaired with Visco-elastic pure Polyisobutene wet application materials with a unique mechanical protection, first developed in 2017 with no failures to date. Read more about our project on the Lethabo Power Station Potable Water Head Tank.
Visco-elastic Polyisobutene is a fascinating material with unique properties that contribute to its longevity. As a visco-elastic substance, it exhibits both viscous and elastic characteristics when undergoing deformation. This means it can resist flow like a viscous liquid, yet also stretch and recover like an elastic solid. These dual properties make it incredibly durable and adaptable to various conditions. The longevity of Polyisobutene is one of its most remarkable characteristics. It is resistant to oxidation, thermal degradation, and most chemicals, which allows it to maintain its performance over extended periods. This durability makes Visco-elastic Polyisobutene an ideal material for a wide range of applications, from sealants and adhesives to lubricants and damping materials. Its unique combination of visco-elasticity and longevity ensures that it continues to be a material of choice in many industries.
Concrete wall penetrations for cables and ducts

Visco-elastic Polyisobutene is a highly effective material for sealing concrete wall penetrations for cables and ducts. Its unique visco-elastic properties, which combine the characteristics of both viscous and elastic materials, make it an excellent sealant. When applied to concrete wall penetrations, it can conform to the shape of the cables and ducts, creating a tight seal that prevents the ingress of water, air, and other substances. This adaptability is particularly useful in situations where the cables or ducts may shift or settle over time, as the Polyisobutene can stretch and recover to maintain the seal. Furthermore, the longevity of Visco-elastic Polyisobutene is a significant advantage in this application. Its resistance to oxidation, thermal degradation, and most chemicals means that it can provide a durable, long-lasting seal, reducing the need for frequent maintenance or replacement. Therefore, the characteristics of Visco-elastic Polyisobutene make it an ideal choice for sealing concrete wall penetrations for cables and ducts.
Concrete floors & walls as intermediate

Visco-elastic Polyisobutene is an exceptional material for sealing concrete floors and walls as an intermediate layer. Its unique visco-elastic properties allow it to behave both as a viscous liquid and an elastic solid. This means it can flow into and fill the irregularities and micro-cracks in the concrete surface, providing a comprehensive seal. At the same time, its elasticity allows it to maintain this seal even when the concrete structure undergoes minor shifts or deformations. The longevity of Visco-elastic Polyisobutene is another key characteristic that makes it suitable for this application. It is resistant to oxidation, thermal degradation, and most chemicals, ensuring that the seal remains effective for a long period. This reduces the need for frequent maintenance or reapplication. Therefore, when used as an intermediate layer in concrete floors and walls, Visco-elastic Polyisobutene provides a durable, flexible, and long-lasting seal that enhances the overall integrity of the structure.
Electrical Junction boxes, substations above and below ground
Visco-elastic polyisobutene, a material known for its unique visco-elastic properties, is an excellent choice for sealing electrical junction boxes and substations, both above and below ground. Its ability to adapt to the shape of the surfaces it comes into contact with ensures a tight seal, protecting the junction boxes from environmental factors such as moisture, dust, and temperature fluctuations. This is crucial for the safe and efficient operation of electrical systems. Furthermore, its durability and resistance to various environmental conditions make it an ideal sealing solution for substations, which contain sensitive equipment. Whether used in above-ground substations exposed to weather elements, or in below-ground substations where groundwater may be an issue, visco-elastic polyisobutene provides a reliable seal that helps maintain the operational integrity of the substation. Therefore, the unique characteristics of visco-elastic polyisobutene make it an ideal material for sealing applications in electrical systems, ensuring the safe and efficient operation of electrical junction boxes and substations.
