Sealtonite® (Special technical component for creating the mineral isolation) 

Sealtonite® is a special polymer component which your mix with a mineral filler like bentonite. Then you add sand which is extremely suitable for this purpose. Mixture’s of Sealtonite® highly effective isolation properties are due to the third ingredient – water. A robust layer of this mixture is installed on-site. It can be immediately covered with a ballast layer of sand or soil, for example. This provides the necessary overburden. Next, any water from the surrounding soil that comes into contact with the Sealtonite® layer will be absorbed. This creates a matrix of chemical bonds between the swelling clay minerals and the dissolved polymer. The resulting strong, dense hydrogel structure has considerably better isolation properties than traditional liners. This swelling hydrogel fills up the pores in the granular filler (e.g. sand). It is this gel’s impermeability and flexibility that make Sealtonite® unique. At the same time, the gritty structure of the filler lends mechanical strength to this mineral layer. The weight of the overlying ballast layer helps to keep the Sealtonite® layer at peak strength, by preventing any excessive swelling.
