发帖数: 645 | 3 Contractor did. I watched the whole process.. It is not easy. Some steel bars are needed. They used about 20 steel bars in my patio. the use of steel bars is to grip the ground. Moreover, you can not dump concrete directly on derts, a layer of sand is needed.
I also did a couple of build-in pots for flowers.
