Abstract
Process for providing foundations and/or reinforcing the ground under buildings and other suitable constructions such as road embankments, by taking out soil and replacing it with a lighter material, which is known as laying compensating foundations. From a number of points over the area where it is intended to reinforce the ground, a plurality of holes is drilled in the soil material or is made by some other expedient soil-removing method, extending in the desired directions, in such a way that soil material is left between the holes. The soil material removed from the holes which have been made is replaced with a plastic material or some other suitable replacement material with a lower density than the removed soil material, whereby the stress diagram which the soil material bears over the actual area is obtained.
