View Full Version : Pro question: one inch or 1.5 inch bluestone

08-13-2010, 06:26 PM
I am contracting new patio. For a dry laid patio using thermaled, cut bluestone, is there any significant advantage to using 1.5 vs. 1.0 inch?
Thanks for your help.

stronger pieces, less chance of cracking if a air pocket or something happens in the mortar.

For a dry lay application I would want to go with the thicker pieces to resist cracking better in the event of the base shifting or settling and a gap forming under the stone. If it was wet the concrete would support the underside of the thinner stone.

I use true 1". Problem with just saying 1" is that there are different grades of stone. You can have a 1" pallet that has 1/2" thick pieces in it.

I use 1" for everything, dry or wet. On occasion, I'll use 1.5" if I feel its necessary.

For dry, we use 1.5". You never know what they client will wheel over the patio (keg of beer, new refridgerator through the back door, new washer machine through the back door, etc). It's cheap insurance.

I see dry walks and patios out of 3/4 inch. I wont touch them with the mower. The pattern cut thermal stuff will actually be consistent in thickness. Ultimately it depends on price difference or just offer the option.
