Hi All, I got a quote for having our path tiled with victorian style (black and white) tiles from a local landscape company. They said external tiles for a path must be 20mm minimum as anything less will crack. Is this true? I have looked at a fair few options and most are 8-10mm. If 20mm victorian tiles are out there, I can't find them.... Only footfall is planned for this path although I suppose a scaffold may go on it one day. Thanks.
I suppose there are two concerns: 1. Most tiles are made in hot countries where wet and freezing weather is not a consideration, so they are susceptible to moisture and cracking. 2. A thin tile might be frost proof, but the thinner it is the more likely frost could get underneath and break the bond with the damp bedding.
So a 6mm tile will crack eventually with British weather and regular footfall regardless of how well it is laid and sealed?
