A wall exposed to wear is made up of wear-resisting, impact-absorbing elements (11) and a structure (10, 12, 13) supporting these elements. The elements (11) are elongate and have base portions (15) to permit mounting the elements on the supporting structure, and arch portions (19) of elastomer or plastic material which extend freely between the base portions and directly pass into a protective layer over the base portions. The thickness of the arch portions amounts to 50% at most, preferably about 30-50% of the total thickness of the element, which preferably is at least about 10 cm. |
