COVER SLAB AND TAPER

For sizes DN 800 to DN 1000, concrete cover slabs are produced. These are reinforced to the requirements of traffic load D 400. Up to DN 1000, the cover slabs are finished with corresponding recesses on the underside to secure them against displacement.

The undersides of the cover slabs and the inner side of taper are given a corrosion-resistant PU covering.

Recesses of different sizes can be order for the top of the cover slabs, for attaching a wide range of covers. To adjust for the final height, compensating elements can, depending on design, be added on site (these are not in our product range) Different sized openings are available to allow entrance. The sizes listed in the following table are intended only as a guide and are subject to design adaptations.
