Mineral barrier, especially for use as barrier over or under refuse dumps

摘要

The mineral seal (2) has a layer (4) of a waterproof mineral extending lateral in a sealed plane. A moistening aggregate system and a humidity sensor element (8) extend parallel to the sealed plane. The moistening aggregate system is regulated according to a comparison of values measured by the sensor element with predetermined nominal values of the humidity. The is composed of at least one layer (4) of a waterproof mineral material extending lateral in a sealed plane. A moistening aggregate system extends parallel to the sealed plane. A sensor element (8) extends parallel to the sealed plane for measuring at least a degree of humidity. The moistening aggregate system is arranged above, within, or directly underneath the seal, and the sensor element is arranged within the seal. The moistening aggregate system is regulated according to a comparison of values measured by the sensor element with predetermined nominal values of the humidity.
