METHOD AND DEVICE FOR INSULATION OF THE GROUND

摘要

A METHOD AND DEVICE FOR INSULATION OF THE GROUND There is provided a method for subterranean insulation of an area of the ground against water seepage therethrough. The method comprises the steps of forming a first trench of a predetermined depth from the surface of the ground and widening the trench by sequentially forming additional trenches along one side of the previously formed trench while simultaneously applying a water repellent layer substantially along the bottom surface of the previous formed trench and while at least partly covering the layer with earth removed from the additional trench being formed until the entire area of the ground is insulated. The invention also provided a device for carrying out this method.
