With Tektoseal Active product solutions for organic pollutants, you can reliably secure and remediate contaminated soils and waters. POPs occur in gaseous form, dissolved in water or in dust particles as well as in soils. With our products, these pollutants can be safely absorbed in any phase. Our product solutions combine the advantages of geotextiles with the particularly suitable pollutant adsorbers, activated carbon and organoclay. Thanks to the high pollutant absorption, it is possible to develop large-area, reliable pollutant filters that make your projects safe and more economical at the same time. The installation of the water-permeable and erosion-proof pollutant barriers is possible on and in soils and also under water.
Our Tektoseal Active solutions with special activated carbon are optimally applicable as permeable barriers for dissolved organic pollutants, such as VOC, TBT, PAH, PCB etc., in soil air and gases as well as surface and ground water. A product configuration with Organoclay is particularly recommended for organic pollutants with oil compounds. For example, pollutants from coal tar, creosote, (so-called non-aqueous phase liquids, NAPLs) etc. can be reliably adsorbed or treated. For a more in-depth analysis of your project-specific challenge, our team of experts will be happy to assist you at any time.
High-performance textiles combined with special activated carbon provide reliable pollutant adsorption from water and gases.
High-performance textiles combined with swellable organoclay ensure reliable pollutant adsorption.
Tektoseal Active with special activated carbon in combination with the optimal geotextiles can be used for the large-scale treatment of dissolved organic pollutants. The persistent substances adsorb permanently and reliably on the activated carbon. The use of the active geocomposites enables soil/sediment remediation with the help of passive soil decontamination. The easy solubility of many organic substances with water is used to specifically induce leaching of the pollutants. In this way, sediments and soils can be treated in-situ and groundwater, humans, animals and the environment can be protected.
Our highly efficient geocomposites with project-specific selected activated carbon can safely bind a wide range of hazardous organic pollutants. Activated carbon is known as an adsorber for pollutant treatment and can be permanently mechanically stabilised and laid over large areas in combination with our geotextiles. In this project video you can see how a very elaborate safeguarding concept can work with a multifunctional and multi-layer surface sealing system made of geobuilding materials and Tektoseal Active.
Our Tektoseal Active product variant with special organoclay offers more effective pollutant protection for organic pollutants in an oily environment. Contaminants that originate, for example, from heavy industry or from the impregnation of wood, cannot be treated effectively with activated carbon in some cases, as the oily substances cover the activated carbon like a film. For these applications, the Tektoseal Active pollutant adsorber Organoclay is the best solution. One advantage: in contact with the substances, the adsorber swells so that the product becomes almost impermeable to pollutants flowing in. It can be used for coal tar, creosote (so-called non-aqueous phase liquids, NAPLs) and many more.
Protection for contaminated soils on land and sediments under water
First choice for organic pollutants with oil compounds
Known and used worldwide as an adsorber for in-situ contamination control
"Chemical treatment of the base material bentonite makes it an oliophilic pollutant adsorber"
Large-area pollutant filters with constant and erosion-proof layer thickness throughout
Project-specific product design for the realisation of very long service lives
Due to the complex natural interrelationships of contaminants, water and soil properties, and adsorption behavior of the active substances, configuring the optimal active geocomposite is not always trivial. With our expertise and laboratory know-how, we support you to find the best-performing solution consisting of special geotextiles and a broad and unique portfolio of active substances. We are glad to run project-specific preliminary tests to gain effectiveness analyses for you. With our holistic services for complex engineering projects, we ensure that “your” Tektoseal Active product solution is as optimally adapted as possible to the conditions on site and can therefore be used safely in the long term.
