    TECHNICAL FIELD OF THE INVENTION
    The invention relates to a flooring system with an underlayer of bulk material, e.g. Sand, gravel, chippings or crushed stone, and a floor covering made of mineral materials, such as natural stone slabs, concrete slabs or ceramic slabs, wood, especially wooden slats or wooden slabs, preferably in the form of a wooden grate, or a composite material of the materials mentioned, placed on it, in particular laid on it or a composite material with at least one of the materials mentioned, such as wood-plastic composite panels, etc. Furthermore, the invention relates to a method for preventing discoloration, light-dark appearance and moisture stains on the surfaces of loosely laid floor coverings made of mineral materials such as Natural stone slabs, artificial stone slabs, concrete slabs or ceramic slabs exist and (especially loose) in bulk material, e.g. Sand, gravel, grit or crushed stone are laid. The process also offers advantages for other floor coverings made of wood or composite materials, in that moisture is better discharged and at the same time the rising of moisture from the bulk material is prevented more effectively.
    BACKGROUND OF THE INVENTION
    Today two different methods are basically known for loosely laid floor coverings that prevent discoloration or moisture stains on the surfaces of mineral materials, respectively. should decrease. In the first method, under the bulk material, e.g. Sand, gravel, grit or crushed stone, so-called drainage mats, laid. These drainage mats should lead to good drainage under the laying material and thus reduce the moisture transport in the chippings, sand or gravel up to the laid paving. In the second method, the back of the panels is treated to such an extent that the transport of moisture from the subsurface, such as chippings, sand or gravel, into the flooring, especially into the mineral flooring, is reduced or prevented before laying. For these protective layers on the back, water repellants, impregnations, epoxy resins or polyurethane are usually used.
    The disadvantage of both methods is that, in contrast to simple installation without a drainage mat or rear panel seal, the installation effort and costs are significantly higher.
    [0004] A drainage mat must be laid extremely cleanly with all connections and terminations and only then can the chippings or gravel be applied and removed as the actual base layer for the paving.
    In the process of back coating, sealing or impregnation, all floor panels must be treated beforehand with the coating, sealing or impregnation. This treatment is preferably done in the factory on dry panels. The coating, sealing or impregnation must dry or harden before the tiles are laid, so these processes require a certain lead time. If the impregnation or sealing is nevertheless carried out on site, the impregnation or sealing and laying alternate, which is usually time-consuming and complicated in practice on the construction site.
    TASK
    It is therefore an object of the present invention to provide an alternative floor covering system for in particular loosely laid floor panels. In particular, a floor covering system is to be provided which has little to no tendency to discolour or form moisture stains and which can be created or set up quickly, easily and cheaply on the construction site.
    SUMMARY OF THE INVENTION
    The invention relates to a flooring system comprising a lower layer of bulk material and laid on the lower layer of bulk material or laid an upper layer of a floor covering (preferably in the form of floor slabs) and is characterized in that the bulk material is treated with a water repellent is.
    [0008] The treatment of the bulk material with a water repellent can also be referred to as water repellent treatment, sealing or coating of the bulk material. The water repellent is applied to the bulk material, e.g. in that the bulk material is coated or impregnated, in particular sprayed or soaked, with the water repellent.
    The floor covering system according to the invention as a whole and in particular its useful covering is characterized by high resistance to aging, especially when it is frequently wet. Advantageously, the treatment with a water repellent can effectively remove and keep moisture from the floor covering or the floor slabs, especially if the floor covering rests directly on the treated bulk material or the treated bulk material layer and thus the moisture transport from the bedding layer into the covering material is interrupted.
    In addition, an aesthetic added value arises from the treatment mentioned, since a consistent coloring of the floor covering, in particular e.g. for natural stone or artificial stone slabs, can be ensured.
    The advantageous embodiment variants listed below lead alone or in combination with one another to further improvements of the floor covering system or define this in further details.
    The hydrophobing agent preferably contains one or more silicon compounds, one or more fluorocarbons and / or one or more paraffins. Water repellants containing one or more silicon compounds alone or in combination with further components are preferred.
    A hydrophobing agent is in particular a hydrophobizing or hydrophobically acting substance or a hydrophobizing or hydrophobically acting substance mixture; or a substance or mixture of substances which makes a surface treated with it water-repellent or more water-repellent compared to the untreated surface. In the present floor covering system, the water repellent is used to make the bulk material water-repellent or, if necessary, to increase an optionally already existing water-repellent effect of an untreated bulk material by treating the bulk material with the water repellent.
    The silicon compound or the silicon compounds are advantageously selected from the group consisting of siloxanes, poly (organo) siloxanes, silicones, silicone resins, organosilicon compounds, silanes and / or silicas. Silanes and / or siloxanes, especially poly (organo) siloxanes, are preferred.
    [0015] The water repellent can be diluted or mixed with water.
    It is sufficient if at least part of the surface of the bulk material or the bulk material grains is treated, coated or impregnated or sprayed or wetted with the water repellent. This means that it is not necessary that every single one of the bulk material grains is completely coated. In particular, it is sufficient if the stripped or leveled layer of bulk material is sprayed with the water repellent.
    The surface covering or the floor panels can or can advantageously lie essentially directly on the bulk material. The bulk material is practically natural and / or artificial aggregates, which are easily available. The bulk material is usually a loose bulk material. For example, the recommended bulk material is sand or gravel, preferably broken material such as broken sand, grit or crushed stone.

    The layer thickness of the bulk material (in particular after leveling) is advantageously 1 cm to 20 cm, preferably 2 cm to 12 cm, more preferably 3 cm to 8 cm.
    It is preferred that the layer of bulk material has a layer thickness of at least 3 times, preferably at least 5 times the grain size of the bulk material.

The bulk material is expediently treated with the water repellent before the floor covering is laid. It is also expedient to treat the bulk material with the water repellent after the lower layer of bulk material has been applied to a floor area. To treat the bulk material with the water repellent, the bulk material with the water repellent can e.g. be sprayed or soaked.

    [0039] Further advantages and advantageous features emerge from the following description.
    DESCRIPTION OF THE INVENTION
    A floor covering system according to the invention is constructed, for example, as follows.
    A bulk material sub-layer rests on a prepared floor area, typically on a downward slope on a dense or sealed substrate, such as concrete with or without a seal or drainage mat. The bulk material underlayer or the bulk material is impregnated with a water repellent or the bulk material grains are coated with a water repellent. A top layer consisting essentially of floor panels (preferably loose) is laid on the lower layer of bulk material. The base plates are e.g. Natural stone plates, concrete plates, ceramic plates, composite material plates, e.g. Wood-plastic composite panels or ceramic-plastic composite panels are used.
    Bulk material is in particular a granular or lumpy mixture that is present in a pourable form. Bulk material expediently comprises natural and artificial aggregates. Natural aggregates include, e.g. Sand, gravel, crushed stone, chippings, crushed sand and rock. Gravel and sand are commonly found in gravel pits. Gravel, usually gravel with a grain size larger than 32 mm, is partly crushed with crushers, which results in chippings and crushed sand. Gravel is predominantly angular, broken aggregate. Artificial aggregates are industrially produced aggregates of mineral origin.
    Sand usually comprises grains (sieve grain) with a grain size (i.e. a grain diameter or equivalent diameter) of> 0.063 mm to 2 mm. Sands are divided into grain size ranges of fine sand, medium sand and coarse sand. For the application disclosed herein, e.g. Coarse sand with a grain size of> 0.63 mm to 2 mm is advantageously used under the sands. Quarried or crushed sand can be used. Cracked sand includes in particular angular, broken or weathered rock or mineral grains.
    Gravel usually comprises grains (sieve grain) with a grain size (i.e. a grain diameter or equivalent diameter) of> 2 mm to 63 mm. Gravel includes fine gravel and gravel with a grain size of> 2 mm to 6.3 mm, medium gravel and fine stone with a grain size of> 6.3 mm to 20 mm, coarse gravel and medium stone with a grain size of> 20 mm to 63 mm. Fine gravel, medium gravel and coarse gravel are predominantly rounded rock or mineral grains, while gravel, fine stone and medium stone tend to have angular and angular shapes (especially broken material).
    Other common names are chippings for grains (Siebkom) with a grain size (i.e. a grain diameter or equivalent diameter) of> 2 mm to 32 mm and gravel for grains with a grain size of> 32 mm to 63 mm. Chippings mainly comprise angular, broken rock or mineral grains; Gravel also mainly comprises angular, broken rock or mineral grains.
    The grain size (equivalent diameter) is the nominal width of a test sieve opening through which the grain just barely fits. The grain size is determined in particular in accordance with DIN 4022 or, now, in accordance with EN ISO 14 688 and EN ISO 14 689.
    A preferred method for building up a floor covering system according to the invention is described below.
    A base layer of bulk material (natural and / or artificial aggregates, preferably gravel or sand, particularly preferably grit) is spread out on a prepared floor surface, distributed substantially evenly over the entire area and removed, i.e. e.g. with a board or a lath, leveled or leveled.
    In the method according to the invention presented here, a coating or impregnation is sprayed onto the bulk material. The bulk material is preferably sprayed directly with the impregnation. The impregnating agent (hydrophobing agent) is expediently sprayed onto the bulk material that has been drawn off, ie leveled and prepared for the further laying of floor slabs. With the impregnation agent (water repellant) used here, even moist bulk material can be treated immediately after the application of a bulk material sub-layer and possibly after peeling off or smoothing (i.e. without interruption for drying, or without a drying step). Impregnating agents or water-repellent agents] which react with water, such as e.g. Silane / SiIoxane emulsions.
    A water repellent is used as the coating or impregnation agent. A water repellent has a water repellent effect. A surface treated with a water repellent has a hydrophobic effect, i.e. water-repellent. A water repellent that is preferably used is based on hydrophobic silicon compounds, in particular organosilicon compounds, hydrophobic fluorocarbons and / or hydrophobic paraffin. Preferred silicon compounds are siloxanes, in particular poly (organo) siloxanes, silicones, silicone resins, and / or silanes. Fluorocarbons are, in particular, substances with perfluorinated carbon chains, but not always exclusively. The waterproofing agent is preferably in the form of a liquid ready-mixed mixture, e.g. as an emulsion (for example a silane-siloxane emulsion), in particular as a microemulsion, the hydrophobing agent preferably being diluted with water for use.
    Ingredients for the preparation of a preferred water repellent concentrate are listed in the following table. Quantities are to be understood as details of preferred usage parameters. The components listed in the table add up to 100 percent by weight. Water can optionally be added to dilute the concentrate, preferably in a weight ratio of water repellent concentrate to water of 1: 1 to 1:25, more preferably 1: 2 to 1:15.
    Here and below where ranges are specified, further preferred ranges result from combinations of the minima and maxima mentioned in the various areas.
    The treated surface is rendered hydrophobic by superficial application, in particular by spraying, of the water repellent onto mineral building materials or the addition of the water repellent to mineral building materials. Mineral building materials in the form of bulk goods are e.g. available as sand, e.g. Quartz sand, or gravel, e.g. Gravel or grit.
    On the impregnated base layer or after the base layer has been impregnated, floor panels are preferably laid loosely (in the usual way). The panels rest on the base course. The panels are expediently placed at a distance from one another so that gaps or joints - with or without joint crosses, respectively. Spacers - arise between the laid panels. Alternatively, the panels can be laid butt joint (i.e. that adjacent panels butt against each other).
    It is assumed that the impregnation treatment of the base layer causes an interruption in the transport of moisture from below into the paving laid on the bulk material. If the floor slabs are laid fresh on fresh, the hydrophobization according to the invention can additionally lead to a hydrophobization of the floor slabs on the rear side due to the direct contact of the laid floor slabs with the not yet set hydrophobization of the bulk material and thereby possibly cause an additional reduction in the moisture ingress from the subsurface.
    A possible explanation for the interruption of the moisture transport is that a barrier layer (esp. A chemical barrier layer) resp. capillary-breaking surface is produced, which has a water-repellent effect and thereby prevents or reduces capillary water transport, capillary moisture and / or the rise of moisture. A prevention or reduction of capillary water transport, capillary moisture, water vapor permeability and / or the rise of moisture has, compared to systems without treatment of the bulk material with the water repellent, a prevention or. Significant reduction in discoloration and / or moisture penetration of mineral panels (natural stone panels, concrete panels, etc.) or other panel materials as a result.
    The method according to the invention provides reliable protection against discoloration, light-dark appearance, and moisture stains on mineral floor coverings when laid loose. The spraying of the water repellent onto the stripped bedding material represents an intermediate step in the workflow, which requires almost no preparatory work and requires relatively little time and effort. In addition to the lower workload, the price of this method is also significantly cheaper than with the known methods with drainage mats or a coating or impregnation applied to the back of the panels before laying.
