If you want to set your wooden decking tiles on the ground, there are a few ways that you can do it. While they may need a bit more preparation than placing the tiles on top of the grass directly, it will save you from many problems. Here are some of your options.

  • Gravel – Because one of the issues is the grass, you just need to remove the grass and other debris from the dirt. You can do this faster by digging a few inches off the ground. Then, cover the ground with landscaping fabric. Then, fully cover the area with gravel, or other similar materials. These materials help provide proper airflow and drainage for your wooden decking tiles. Before setting the tiles, make sure that the ground is flat. Use a tamper to even it out.
  • Cement or Concrete – Another excellent way to set your wooden decking tiles is to build a cement or concrete slab. To do this, you will need to clear the area. You will also need to dig a few inches according to how thick you want the pavement to be. Then, you have to cover the area with a mix of coarse and fine aggregate. Make sure that the ground is smooth and flat. Then build a frame out of wood and pour the cement or concrete. Let it dry, and place the wooden decking tiles directly on top.
  • Pre-existing decking or pavement –  Lastly, you can place your wooden decking tiles over any existing decking or pavement. You don’t need to make any adjustments as long as the surface is even,  free from moisture and has sufficient drainage and airflow.
