Landslides need to be thoroughly researched and studied. Designs for slide stabilisation may be different as related not only to the cause but also to the technical feasibility and economic practicability. The selection of the works and their construction is increasingly depending on the economic factor. A landslide will be prevented by increasing the soil resistance or strengthening the zone of the sliding surface. This effect may be accomplished by incorporation of new geo-structural elements, the „concrete elements”. Unlike the conventional landslide stabilizations, where the supporting construction for the whole mass of soil, from the sliding to the ground surface, „concrete elements” are incorporated only in the sliding surface zone, and where necessary soil reinforcement. They use less material and labour and thus are more cost-effective. „Concrete element” is a new geo-structural element composed of concrete tube-ring and filling. The concrete tube-rings, or short cylindrical units, are incorporated one by one in a bored hole through the zone above and beneath the sliding surface, and then filled with crushed aggregate or gravel. This rigid structure – ”Concrete elements” through the sliding surface is receiving the sliding force and transferring it into the stable soil under the sliding surface.
