Random building stone is cropped to a 100mm – 150mm (4-6 inch) bed width as standard, providing at least one usable face per piece. (‘Bed width’ is the width of your footing). Heights and lengths are naturally random, hence its name – although you might also hear it called facing stone, random cropped building stone or random rubble in the trade.
One bulk bag of random building stone cropped to the standard 100mm – 150mm (4-6 inch) bed width will provide enough material for 3 to 3.5 square metres of facing stone. A wastage allowance of 10% should always be calculated into your figures when ordering.
The natural variation in the shape and colour of real stone means that every piece of sandstone is unique. As such, working with random building stone requires the skills of a trained stone mason or appropriately experienced builder. It’s a technique that’s suitable for house construction and commercial / public buildings, restoration and renovation projects, boundary or retaining walls, dry stone walling, garden features and any kind of building project that involves the use of natural stone.
