So its is actual stone, just very thin? Yes, that's exactly what it is. The diamond tipped circular saws are huge and cut extremely accurately. After cutting, the stone panels are polished on one side and the edges. The thinnest panels I have seen were 10mm thick, but there may be thinner ones - they make granite and marble tiles that are probably thinner. My interest in the subject came from buying tens of thousands of tonnes of granite waste from the Norwegian and Swedish stone quarries to be used in sea defence works. The wastage is tremendous; the quarry I dealt with most only managed to turn 7% of its output into monumental stone, so 93% went to waste. They originally offered the waste for free, so all we had to do was send barges to collect it, but they subsequently got very organised and sorted it into weight bands, and charged for it. But it was still comparatively cheap as all they wanted to do was get rid of it so their quarries weren't choked with waste stone. Clever. So when did they start using this instead of those blue mdf walls? Will they be doing this in future, when they have building works (at bond street, for example, or TCR) ? I have no idea, sorry. |
