Problems solved by technology

[0009] The defect of the cover layer made of solidified mineral aggregates is the lack of connection to the foundation, which precisely impairs the mechanical stress of the outer ground during the freeze-thaw transition

Embodiment Construction

[0040] FIG. 1 schematically shows the multilayer structure of a floor covering 1 according to the invention in a cross-sectional view. The floor covering has three layers in the present embodiment, the lowest layer, the substructure 2 , being laid on the foundation 3 . Before the substructure 2 can be laid, the foundation 3 must first be prepared. Dig the foundation to a frost protection depth of 40 to 60 cm. The excavation depth depends on keeping the connection between the substructure 2 and the foundation 3 unaffected by the erosive effects of the freeze-thaw transition.

[0041] The substructure 2 itself consists of a layer of sand on the foundation side, the so-called sand layer 4 , and a crushed stone layer 5 lying thereon. In addition, firstly a filler material consisting of cement and sand is prepared, which are mixed with one another. The bonding material is a two-component polyurethane bonding material. It is also possible to use two-component epoxy resin adhesiv...

Abstract

The invention relates to a water-permeable paving (1), for application on a ground. The upper part (6) of the paving (1) comprises a combination of compacted mineral aggregate and organic adhesives. Said paving (1) has a multilayered structure with an upper part (6) and a lower part (2), whereby the lower part (2) comprises at least one layer of sand (4) on the side of the ground and one layer of gravel (5) on the side of the upper part, the average size kSchotter of the fine particles being 5 mm. The invention also relates to a method for producing said paving.

Description

technical field [0001] The invention relates to a water-permeable floor covering for laying on foundations, wherein the superstructure of the floor covering is a mixture of compacted mineral aggregates and organic binding material. Furthermore, the invention relates to a method for producing such a floor covering. Background technique [0002] Ground stabilization by ground covering layers is a known technique. The floor covering is used for paving streets, squares, building enclosures and other walkable or driveable surfaces. Concrete overlays, asphalt overlays, gravel overlays, and wood overlays are common. Disadvantageous for the drainage of surface water is the limited or complete lack of water permeability, so it is often said that the surface is sealed, and people try to solve this problem by means of mostly expensive drainage equipment. [0003] An ecologically undesirable side effect of surface sealing is increased loading of the channel, which turns into violent ...
