Installing a flagstone patio around a pool

The owner had fixed the old concrete pool deck twice and it crack again. She was tired of repairing the pool deck so she called River Rock Landscape and here’s how we installed flagstone around the pool. We removed the old cracking cement pool deck, added 3/4 crush gravel. Compacted it solid. Rebar every 8 inches.Then we mixed the cement (1 part cement 3 parts sand ) We do 1 wheelbarrow at a time and lay the flagstone so the joints are in as close as possible.The cement was at least 6 inches thick. It seems a little over kill but its going to last a life time .The owner is still happy to this day.
