Will be pouring our first concrete patio next week, and just unclear about a few items. 1. Patio will take about 5CY of Ready Mix, but I am uncertain as to whether wire mesch is needed. We put in 6-8 " of 21A C&R, andwill tamp it Monday. It is just a patio so my thought was to not use mesch. Thoughts? Forms are all in. For a patio, What is the best material for expansion joint? A PT 1x4 was mentioned, but would rather use something better looking for a patio. What type of concrete is best given what was stated above? Thank You in advance.
