I love the look and feel of high-quality composite decking but I want it flush/level with the ground. In other words, I don’t want to step down off the deck. I particularly don’t want my small children tripping/falling off the edge of the deck, and I don’t want railings since I have a small backyard in the city.
Contractors all want me to build it above-ground for airflow, or they say I can dig down 8” or so and build the foundation there. But they caution me that the reduced airflow will cause the treated lumber foundation to rot over time. I don’t want that.
Please be creative with your answers. Could we perhaps pour concrete first and then put composite on top of something made of plastic?

.... are you saying that they refuse to build it? .... maybe you are not explaining it correctly, because it is always "above-ground", no matter how high – jsotola Apr 12 '18 at 19:22
