A device, system and method for protection of concrete elements against soil forces. The system comprises two slabs made of a compressible material. The slabs are vertically standing and facing inner sides of each other. Each of the inner sides comprises a wedge having a bearing surface in an upper portion thereof. A horizontal slab is mounted on the bearing surfaces. When the concrete is poured, it is bounded by an upper face of the horizontal slab and by the inner sides of the vertical standing slabs. Thus, a large void is formed between the concrete and the ground and swelling soil may fill this void without affecting the concrete element of above. |
