Definitions

  • the present invention relates to a paving tile or replica flagstone for a wide variety of applications, and suitable for both indoor and outdoor use.
  • tiles or paving stones or flagstones are used to form a floor surface or to replace an existing floor surface, either where the existing surface has become worn or damaged, etc. or where a new effect is desired.
  • Such paving stones are available in a wide variety of materials, colours, patterns and sizes.
  • the base onto which the stone is to be placed needs to be prepared.
  • the surface onto which the stone is to be placed needs to be excavated to the required level.
  • a granular fill material is then spread over the surface and compacted.
  • a geotextile is then arranged in place, to provide stability.
  • a bedding layer of kiln dried sand should be provided.
  • the paving stones are then arranged in place, in the desired pattern and must then be vibrated and compacted to provide a firm, final surface . Concrete supports need to be placed around all edges, to prevent lateral spread of the paved area.
  • the aim of the present invention is to provide a paving stone which can be used to form a desired surface without the need for such time and cost-consuming preparation, and without the need for excavation, etc. of the site.
  • a paving tile formed of an aggregate and resin mix, wherein the tile is formed such that the top surface is aggregate-rich relative to the bottom surface and the bottom surface is resin-rich relative to the top surface.
  • the invention provides a method of manufacturing a paving tile comprising pouring a mix of aggregate and resin into a mould; vibrating the mould such that one surface of the resulting tile becomes aggregate-rich relative to the other surface and the other surface is thus resin-rich relative to the first surface.
  • Figure 1 shows a sectional view of the preferred embodiment of the paving tile of the present invention
  • Figure 2 shows a sectional view of the bottom, resin- rich surface of the tile, onto which an aggregate is broadcast to provide a mechanic bond with the adhesive;
  • FIGS 3, 4 and 5 show different possible layouts using tiles according to the present invention.
  • the paving stone is in the form of a tile manufactured from a mixture of polymer resin and crushed, graded stone, sand or other aggregate. Coloured pigments may also be included to provide a desired colour or colour combination.
  • the tile is manufactured using a mould which may be formed with a cast surface impression to provide a desired surface appearance, including a brick appearance, cobbles, asphalt, terracotta or quarry tile surfaces, etc.
  • the edges of the tiles are serrated or, at least, not straight lines so that when the tiles are laid together, the join between adjacent tiles is less apparent.
  • Certain tiles can be formed as border tiles, having at least one straight edge to form the boundary of the paved area.
  • the paving stones according to the present invention are manufactured by pouring the mixture of polymer resin and stone into a mould.
  • the mould is then vibrated such that the stone components interlock and fall to the bottom of the mould, resulting in a stone-rich top surface of the tile when it is removed from the mould.
  • the paving stones are formed in a mould and are made such that as- the material is poured in to the mould, the bottom surface of the mould defines what, in the end product, will be the top surface of the tile.
  • the moulds used have a deep textured surface which is the negative of the upper surface finish of the paving stone.
  • the moulds are formed such that the end product has a high slip resistance and has the visual appearance of the traditional stone being replicated, e.g. cobblestones, etc..
  • the paving stone is formed from an aggregate, together with coloured pigments, chopped mineral fibres and polyurethane resin mix and is preferably formed from a carefully controlled blend of up to three aggregates, having predetermined particle size, grading and hardness, together with chopped mineral fibres and polyurethane resin. This is all then mixed to a predetermined consistency.
  • the mixed medium is then poured in to the moulds, ensuring that mixing continues so that all aggregate particles are kept in suspension in the material, and allowing for a consistent concentration of aggregate throughout the product .
  • the moulds are then vibrated, preferably at a specified frequency and for a specified time interval, such that the aggregate particles interlock and migrate towards the bottom of the mould, which, in the end product, forms the upper surface of the paving stone.
  • This stone-rich upper surface produces the required surface skid resistance.
  • the top of the mould which is then the bottom surface of the resulting paving stone, is resin rich and this surface then allows a good chemical bond between the paving stone and the adhesive applied thereto, during installation.
  • the product is then left in the mould until it is cured to a desired consistency. Stones of a relatively large particle size are then scattered over the upper surface (which will be the bottom, resin-rich surface of the end product) , and allowed to sink in to the partially set mix. In the preferred embodiment, this large particle aggregate layer is allowed to sink up to 50 percent of its diameter in to the mix. This allows a good mechanical bond to be formed between the stone and the adhesive on installation.
  • the resin-rich surface thus provides a surface which ensures a good mechanical and chemical bond with an adhesive.
  • the tiles can then be placed onto an existing surface, by use of an adhesive, without the need to excavate or remove any existing surface.
  • the existing surface only needs to be smoothed, if necessary, to ensure a smooth profile onto which the stones or tiles of the present invention can be laid.
  • the tiles are then adhered to the surface by means of an adhesive applied to the surface substrate, into which the tile is bedded.
  • the adhesive is preferably a polymer-based adhesive which is fully compatible with the resin used in the tile material, to ensure a good chemical and mechanical bond.
  • the preferred installation method is as follows.
  • the existing surface must be sound and all loose materials should be removed.
  • the surface should be levelled by grinding off high spots and filling in low spots with, for example, mortar or other suitable compounds .
  • the preferred adhesive is a two-component polyurethane adhesive. Predetermined quantities of the two components are mixed together until a uniform colour is achieved and the adhesive is then spread on to the prepared surface to form a uniform adhesive layer of, for example, around 0.5mm.
  • the tiles are then bedded into the adhesive, before the adhesive sets (preferably within 30 minutes of mixing) .
  • the large particle aggregate layer forms a good mechanical bond with the adhesive and the resin-rich bottom surface of the tile forms a good chemical bond.
  • the border tiles are put into place first, and then the area defined by them is filled in with tiles in the desired pattern.
  • the preferred type of stone for such tiles due to its hard-wearing properties, is flint and the preferred type of polymer resin is polyurethane resin.
  • polyurethane resin any type of hard-wearing stone or sand material can be used and other polymer resins are also suitable.
  • the tile of the present invention provides an economic, hard-wearing and widely applicable alternative to existing stone paving and, in fact, laboratory tests have shown that the stones made according to the present invention last five times longer than standard concrete paving. Because of the moulding process and materials used, the stones of the present invention can be formed to replicate any type of texture or surface, e.g. cobbles, granite, brick, etc. in any composition.
  • the tile is made of a combination of stone and resin, it is, compared to existing paving slabs much lighter.
  • the tile is relatively thin, but equally or more hard-wearing than existing paving stones.
  • the tiles can be laid by unskilled persons and are, therefore, suitable for DIY use, e. g. for laying driveways etc.
