Calibrated Sandstone Paving

London Stone have an important announcement to make about the specifications of our natural sandstone paving.  From January 2011 all sandstone paving supplied by London Stone will be calibrated to a depth of 25mm.  Many of our competitors supply Indian sandstone calibrated to a depth of 22mm.  London Stone don't think that 22mm is thick enough for exterior stone paving, particularly when used in high traffic areas.  It might not seem like a big difference but natural stone calibrated to 25mm will on average be over 40% stronger than stone calibrated to 22mm.   Coming in January 2011
