Pier Foundation for a Shed
(Arlington, Texas, USA)
I have to build my 10' x 10' shed close to a tree with exposed roots so I am going to elevate it and I was thinking of using concrete blocks to build it on.
I bought a Heartland "Rainier" kit with 2x3 boards to make floor with but as it is rather large I am concerned about the blocks sinking into the ground and was thinking about putting the blocks on top of some sort of gravel after tamping down the ground with some sort of heavy object.
How many blocks should I use. Are blocks even a sound idea? I read about the plastic sheet under the shed and thought that was a good idea. does the plastic sheet go under the blocks or attached to the bottom side of the floor. There is standing water after it rains so that is also a consideration as I can not stop that. Also I have a clay soil.
Thank you for your consideration
