Thus, the product obtained is one of high water absorption, high viscosity, high gelification capacity, high thixotrophy and low electrical resistance. Let this artificial soil consolidate naturally, without tamping it down.

Due to its colloidal size and its special crystal structure, this gel can absorb and adsorb water at a proportion unreached by any other clay mineral before fold its volume.
