Square flagstone on pre existing concrete
Thank you in advance for your assistance. I am attemtpting to convince
my husband that we can lay our own flagstone. We have a rough pebble/concrete
surface which as be in place for years. Question: Do we need to put
concrete mortar under each flagstone, then grout with same after setting?
Am I correct to assume this is the only way to avoid uneven movement?
And lastly, does anyone have a great flagstone source in Northern Virginia?
Look forward to your comments. Sandi
