This photo shows an example of a Manitoulin random mortared flagstone patio. Depending on the situation mortared flagstone is either installed on a 3-4" layer of concrete with a 1" bed of mortar between the flagstone and the concrete.
There are many different options for flagstone that can be used! Some of them include Wiarton Flagstone (most common), others include India Stone and Sandstone.
Flagstone can be laid one of two ways; either dry laid or mortared. The mortared method
consist
of:
- Excavating down 11".
- Back filling with 6" of 3/4 clear
Aggregate.
- Compacting all the gravel with adequate tampers.
- Installing a
3-4" concrete slab.Laying
out all of the flagstone, and cutting it in to fit properly.
- This can
be a very tedious part of the job, and is a lot like a jig saw
puzzle.
- Setting the flagstone in a 1-1.5" mortar bed. (Because flagstone
isn't as consistent at man
made products it usually requires for each stone to be set
individually. This can be a bit of timely process as its done with
lasers, and string lines).
- Lastly we joint everything with mortar, and tool all the joints smooth.
