Granite is a particularly tough material especially suitable for external use. Virtually indestructible, it resists both chemical and atmospheric attack and apart from the occasional clean, requires no other maintenance. Choice of finish is wide. It can be supplied polished, honed, textured, dolly pointed or fine axed according the required effect.
Marble, Limestone, Slate and Sandstone
Marble, limestone, slate and sandstone also possess properties of great physical strength and durability but since they can be affected by climatic conditions they are more suited to internal use unless external areas are accessible for frequent maintenance. Marble can be supplied polished, honed flame textured and sandblasted and is available in wide variety of colours and patterns creating interesting and aesthetically pleasing finishing effects.
Limestone is available honed, sandblasted, flame textured and sandblasted, colours ranging from pale ivory to yellow. Hard limestones are increasingly being used on the external elevations of buildings.
Slate is a durable, hard wearing surface that is impervious to sunlight and therefore will not fade, available mainly in greens, black and blues, it can be supplied honed, riven, flamed, sandblasted and waterjetted.
Granite, marble, limestone and slate can be cut and shaped to size and thickness according to specification. Non-standard thickness can be supplied for special requirements.
Approximately 50 kilos per square metre for 20 mm thickness.
Modular or cut to special sizes or shapes, granite is the better choice for heavily trafficked areas and is virtually maintenance free. Marble, limestone and slate perform well but need regular cleaning and maintenance, which can be reduced by initial vitrification. Generally, panel sizes should be kept below 700 x 700 mm. Fixing is either on a sand and cement bed or by hi tech adhesive to a pre-installed screed.
