The QSE sealing material is a high-quality clay raw material in the form of pellets with a diameter of 6 mm or 8 mm and a length of 5-12 mm. On contact with water, QSE pellets increase their volume as a result of swelling, forming a homogeneous plastic mass used as a sealing material. It is assumed that ~1 litre of seal is obtained from 1 kg of QSE.
There are numerous possibilities for using QSE pellets, provided that water is available in sufficient quantity and there are no obstacles to placing them at the spot to be sealed.
The pellets are used wherever a plastic seal with a very low permeability coefficient (~10-8 m/s) needs to be created. The product works well both for sealing off aquifers in water wells and in all kinds of engineering works. After reaching its maximum degree of swelling, the material remains plastic and “cooperates” with the surrounding layers. However, it should be remembered that no permanent setting process takes place in this case. A seal exposed directly to weather conditions will tend to gradually release water and shrink, regaining its properties on renewed contact with water.
QSE pellets are available in 25 kg foil bags (40 bags per pallet) or in so-called Big Bags (1000 kg).
NOTE
Once the bag has been opened, due to its high hygroscopicity, the material must be stored in a dry place.
