This was a quick and easy one day project, well mixing the concrete wasn't so easy, but the rest wasn't too hard. It took two 80# bags of premix concrete and some precast landscaping boarder stones. You can use use a short block of 2x4 as a float if you want. A regular shovel is the only other tool needed. Of course you do need some type of mixing tub as well, but a small one will do. I mixed the concrete a little on the dry side.
I only made this about 2" thick so I used a high strength mix with the fiber reinforcement. A small extra cost but worth it I think.
