Flagstone patio--mortared vs. gravel/sand?????

19 years ago

We need some advice on laying a flagstone patio...

We originally planned to lay the patio on a gravel and sand bed with the joints filled with sand. However, the guy doing the landscape design said we need to mortar the patio if we plan to use it for entertainment purposes, such as having a table and chairs on it. He states that if we do not mortar it we will chip the edges of our flagstones and it will eventually need to be redone.

We are located in the northern California foothills, where the weather varies from mild winters to hot summers, with occasional freezes in the winter months.

Any recommendations would be greatly appreciated.
