These very hard tiles are made for very heavy industrial use, but also feature a beautiful metallic sheen.
Originally used for sewerage systems or piping pieces, these pavement tiles are made by melting natural basalt and casting it into metal moulds. Paving tiles cast in this manner feature excellent properties, making them suitable for use in industrial operations where they will be exposed to mechanical and/or chemical loads. They are also often used because of their attractive and uncommon appearance.
This range covers tiles with smooth or anti-slipping surface and their various accessories, such as coved tiles, so-called L-pieces, and many atypically shaped tiles. The colour of each tile is determined by the nature of the natural material and cannot be changed or painted. Each tile is an original in its appearance and thus also the floors made from the tiles are unique.
These basalt tiles are produced with three basic types of backside finishes: With rough grooving – so-called rough raster, with fine grooving – so-called fine raster and without raster – so-called smooth tiles. The sizes are variable. The tiles with rough raster are used for laying into bed from wet concrete mix, or it may be glued by binding material similarly as ceramic tiles onto a prepared, properly cleaned, matured and compact concrete bed. The surface of basalt pavements is dust-free, it is easily maintained with common and mechanical cleaning means; this applies also for anti-slipping pavements, where the offsets are designed for easy cleaning. Basalt pavements are also resist to strong chemical agents used for sanitary cleaning works. The manufacturer recommends to clean interior pavements after assembly with 8 % vinegar, wax with common substances for maintenance of the floor covering and then wipe with wet cloth.
JR – The tiles with fine raster are used for gluing by binding material similar to ceramic tiles onto prepared, properly cleaned, matured and compact concrete bedding. The use of this raster is advantageous also for special adhesives and binders, e.g. in chemical operations, regarding the decreased consumption of the adhesive.
H – The smooth tiles are used very rarely and mainly for special purposes, where extreme minimum thickness and minimum consumption of the basement adhesive is required. As a standard, the raster tiles with R and JR grooves are produced. The products of melted basalt are, particularly on casting into the metal moulds, smooth, practically with zero imbition. For better adhesiveness to the binders, the non-working sides are fit with finer or rougher grooving, and additionally the sand is pressed into the surface during casting. The surface is roughened by individual sand grains, which are firmly bound to the basalt.
Adhesive capacity tests have proven that these „sanded” castings feature very good adhesiveness both to classic, and to modern synthetic binders.
