I currently have a drylaid stone walkway that needs to be rebuilt. However,
i do not want the stones to shift in the manner that they did (that walk is
only a couple of years old). I am contimplating setting the stones in
mortar. I have heard that this can be done over a layer of sand over a
layer of compacted limestone with fines. But on the other hand, i have also
heard that a reinforced concrete base is necessary. Is a concrete base
needed for mortared walkways as well as mortared patios? Any suggestions
you have would be very helpful. Thanks.

Hi, can you please comment on how to put new mortor between flagstone slabs
on sand. The pation is fine. Still very level and solid. But the mortor
after years of weathering has started to crack and come up. How do i put
(and what do I use) for new mortor between the slabs?
Thanks,
Tom

I've been told that there is a "sand" mortar mix somewhere that you lay
flagstone on and sweep into spaces then water with hose...and it hardens
and stays put.....is that true ?

The sweep and spray material is a polymeric sand that will fill in the
gaps, prevent ants, and weeds. One brand is called techniseal and can be
found online at www.techniseal.com.

I have a 40' x 10' area i would like to do in flagstone. my budget is real
tight and soil around here is almost impossible to dig in. so i am trying
to find the best way to do this on a TIGHT budget. I am not looking for
perfection just something that looks nice and will last a little while
without killing myself or my wallet. Thank You.

We recently had a flagstone patio installed onto a concrete slab. The
methods used were the same as recommended above, except the concrete slab
was poured a few months before the stones were laid, mortred and grouted.
The problem is that many stones began to rock a few millimeters and their
grout is cracked. The contractors have been back three times to try to fix
it. They ground out the grout of the affected stones, squeezed in mortar
where possible and regrouted. They tried a few different mortars and
different grout but nothing has fixed the problem and about 25% of the
stones are affected. The contractors are reputable and built our house 8
years ago as well as this more recent project, but they are stumped. We
live in southern CA.
Do you have any ideas as to the root cause and how to fix it?
Thanks

I am having thet same problem as Kate from S. California with flagstone set
on a concrete base. Different contractors have repaired it and it still is
lifting and the mortar is crumbling.

We would like to replace our worn pressure treated wood deck(20 years
old)with a flagstone patio. Currently the base under the slightly raised
deck (raised about 16") is a layer of stones over plastic. What would be
the best way to replace the decking with flagstone, and can the stones be
utilized, such as putting a thick sand layer over them?
I also like to look of moss between the flagstones. Therefore, would a
sand base be best?
