flagstone mat on decompossed granite walkway

by bob
(reno)

the home i purchased several months ago has flagstone
mat on decomposed granite with dirt placed in the joints (walkway)

the stones are thin and several are very loose, thus a few have cracked

short of removing them and installing concrete....is
there any jerry rigged way to salvage this walk?

it looks great and the stones dont crack if they remain secured down

is there any way to mortar stones to decomposed granite?

i am retired and don't have funds---i have the time

could i level and mortar the stones edges 1 by 1 to
salvage the walkway?

thanks dave,

those 1/2" flagmats are designed to be mortared
to a solid surface

the glue blobs create break points when there is
any type movement

because they were laid in a pattern and cut prefectly, i pulled them up 1 at a time and cut
off the glue blobs creating break points under neath---that took 3 days and due to exhaustion i
mortared all the joints without buttering the bottom

it seems very stable now---some people dont like
mortar--i think it looks good

i know about polymers from ther asphalt business
and they are designed to self harden (compact) without being sticky---easy installation

why would anyone use dry sand when they can have the same sand harden with polymers

thanks for the reply---thank god i have a gate so no heavy load can get on this walk or at 1/2 to 5/8 inch it would crush easily

if the mortar fails ..i'll have to butter the bottoms 1 by 1

polymeric sand

Dear Bob,

There's a product called polymeric sand that binds stone together. It's so new that my father has never used it.

Call your local building supply store or ask a local stoneyard and they should be able to get it for you.

There are also hardeners out there that can help stabilize your decomposed granite.

Great luck!

David
