Abstract: The protective wall (5) has a flat, tabular or cubic configuration which has a section of a water-impermeable building material. The building material of the protective wall is a compound of compacted, mineral aggregates and an organic adhesive. Mineral aggregates such as sand or gravel are building materials which occur in plentiful amounts in nature and can be acquired simply and inexpensively in large quantities on-site. Mixed with an organic adhesive, the building material has a viscous consistency and can be produced and processed easily. By means of appropriate shaping, the protective wall can be configured in a variety of dimensions, frequently curved. The protective wall is suitable for sealing dykes to protect them against erosion in coastal or liquid-side high-water protection.

Abstract: The superstructure (2) of a carriageway is embodied in a multi-layer manner and comprises, as the surface and first layer (3), a hardened compound consisting of glass particles, an organic adhesive, and a polyurethane adhesive. The glass particles are a mixture of glass beads and broken glass. The light-positive property of the glass particles of the compound enables the colour of the adhesive to be continuously transmitted from glass particle to glass particle up to the surface, such that the colour can also be seen when the glass particles are worn down or the adhesive is soiled or becomes turbid on the surface side. In this way, permanent colour stability is ensured even when the surface is worn down. The surface thus maintains the aesthetically pleasing or indicative colour thereof.
