Tektoseal Active product solutions for inorganic pollutants, can reliably secure, remediate or preventively protect contaminated soils, sediments and waterbodies from pollutant input. Our product solutions combine the advantages of geotextiles with the active substances particularly suitable for this purpose - our cation adsorber and zeolite. As a result of fast and high pollutant absorption, it is possible to construct very thin and secure pollutant filters for heavy metals, phosphates and radionuclides, making your project even more sustainable.
Application of the large-area, permeable and erosion-proof pollutant barriers is possible on and in soils as well as underwater. Our Tektoseal Active solutions with the particularly powerful cation adsorber, are optimally suited as permeable barriers for substances such as lead, mercury, arsenic etc.. A product configuration with zeolite increases the cation exchange capacity of filter and barrier layers. For a detailed analysis of your project-specific problem, our team of experts is at your disposal at any time.
High-performance textiles combined with a special cation adsorber ensure the highest pollutant absorption capacity.
High-performance textiles combined with zeolite (mineral molecular sieve) ensure reliable pollutant absorption in soils with low cationic contamination, among others.
Tektoseal Active with a special cation adsorber serves as a high-performance pollutant barrier for heavy metal pollution applications and has also been used to remove phosphorus from water. In addition to removing inorganic substances from the water, the active substance neutralises acidic water to a neutral pH value. The specific pollutant filter can be used over a large area to prevent environmental contamination by e.g. nickel, aluminium, copper etc.. In addition, already polluted media can be secured and passively decontaminated at the same time. For example, sediments and soils near mines, heavy industry and other potential sources of danger can be treated passively. This protects surface and groundwater, people, animals and our environment without the need of plant treatment measurements.
Our highly efficient geocomposites with special cation adsorbers bind a variety of hazardous inorganic substances. The cation adsorber is a demonstrably highly efficient active substance for the treatment of pollutants and, in combination with our geotextiles, can be laid in a permanently mechanically stable manner over large areas.
- Proven affinity to many metals present in the environment at high and low concentrations
- High pollutant absorption capacity enables long service life
- Strong binding between active substance and pollutants minimises system reversibility (desorption)
The high affinity as well as the large capacity for various metals and radionuclides present in the environment can be demonstrably measured. A breakthrough of the active material can only be detected after large quantities of metals have been discharged (see graph above). In field tests with mine water, the laboratory results can be confirmed with regard to effectiveness, capacity and the exclusion of system reversibility.
Depending on the challenges on site, a Tektoseal Active product variant with zeolite - the mineral molecular sieve - can also be advantageous. Zeolite has a high cation exchange capacity and can be used, for example, as part of the backfilling of old building materials, contaminated soils or ash. In order to comply with limit values for the storage or securing of these materials in the field or to use them as a building material, zeolite can be an economical alternative. The many boundary conditions associated with inorganic pollutants mean that the selection of the optimal adsorber should be determined, if necessary, with the help of preliminary tests. This is what we offer you through our experts and engineers.
Realisation of a high cation exchange capacity in the filter or barrier layer
Safeguarding of contaminated soils in the field
Additional safety when building with substitute building materials and slightly contaminated materials
Project-specific and economical product configuration by our experts
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.
