摘要：
The invention relates to a method of rendering a soil or another material like a mortar, a binder, or a concrete impervious by injecting it with a silica solution. A finely ground powdered compound containing calcium with a solubility in water of between approximately 0.01 g/l and approximately 2 g/l is mixed into the silica solution, which has a ratio of SiO.sub.2 to Na.sub.2 O of between 1 and 1.3, before injection.
