dry laid patio - question
I'm putting in a 100 sq. ft. dry laid patio of flagstones. I've priced the
sand I'll need (2 inch foundation, 1 inch fine sand bed) at c. $220 incl. $50 to have it delivered by truck. My question is, do I absolutely need the foundation and bedding sand? Can't I just dig a shallow bed c. 1 in deep, level it, lay the stones, and then fill in the cracks with a single 50 lb bag of sand? I don't care if weeds and grass grow in the cracks. Mike |

You can, but its damn hard work! The purpose of the sand is to flow slightly, so that you can lay and level the slabs without cracking them. I do lay some of mine on earth, but my soil is 60% sand and I do it only when the soil is dry - and even then it is only the 3'x2' slabs I do that to, and I have several dozen surplus ones. Anyone want any? You want sharp sand, not fine sand, incidentally. But, lastly, 220 quid plus 50 quid delivery for less than a cubic metre of sand? Tell those crooks where to shove their sand and find some honest supplier. Look at Cormaic's pages on this. If your soil is stable (i.e. NOT organic and preferably sand or gravel), you don't need a foundation for pedestrian use (or even just cars, really). You need to make sure it is well and uniformly compacted. But you DO want 1-2" of sharp sand to lay slabs on, unless you want to spend ages or break lots of slabs. Regards, Nick Maclaren. |
