Method and apparatus for affecting or changing the liquid content in a soil stratum, either by draining or by infiltration. A liquid conductor provided with slots is driven down into the soil stratum, whereafter it is filled via supply means with a material under pressure such that the material is pressed out of the conductor through the slots towards the stratum to form radial cracks therein, these cracks being simultaneously filled with the material in question. The material, which is a multicomponent material, is taken in component form through the supply means, whereafter the components are mixed, and under the action of the water in the soil stratum go over to solid form with open cells or ducts. |
