Definitions

• the invention relates to a slab-shaped concrete block - hereinafter called a concrete slab - for soil coverings, in particular for liquid-tight paving slabs.
• any further spreading of the substances should be avoided in the event of any leakage, spillage, leakage or the like.
• fuel and oil can get to the ground in the area of petrol stations and be carried out of the petrol station area by vehicles and pedestrians.
• the object is achieved by the characterizing features of claim 1. Then the top of the concrete slab is divided into fields by grid-like dummy joints.
• the existing dummy joints act as drainage channels so that any liquid that may have leaked can run off through the dummy joints and the surfaces of the fields remain largely free of liquids.
• the liquid is not carried on by walking on or driving onto the concrete slab.
• the shape and size of the fields preferably corresponds to that of a paving stone.
• partial plates Parts of it, so-called partial plates.
• the latter are designed according to the invention with a length of 1/3 and / or 2/3 de concrete slab length.
• This type of division enables extensive adaptation to the required laying widths without a bandage laid from such concrete slabs having unevenly running lateral edges. As a result, any additional drainage channels that may be required can be created easily and cheaply at the edges.
