ecological and its method of preparation from shale reconstituted

摘要

P & this invention relates to a geological barrier impermeable to liquids and ecologically acceptable made of shale / p & & p & it is used as a stratigraphic shale that coming from the system of the upper ordovician just below the system of the silurian stratigraphic. The shale is removed to expose the solid shale not having been subjected to atmospheric agents to its initial state sedimentation. The shale is then extracted and then ground in an aggregate which can easily be compacted. The water is added and mixed thoroughly the aggregate of shale to disperse uniformly water. It extends immediately in a layer of uniform thickness along a wall to be sealed, and is then treated and the cup to the solid state by passing the roller in the feet of sheep. The operation is repeated until the thickness and width necessary for the barrier / p & & p & application to the sealing of the cavities used as a discharge, in particular for municipal waste. / p
