Can a patio be made on ground in a yard, and if so, what kind of prep would be needed?

We recommend installing our Eco-Lock Rubber Tiles over a hard flat surface, so you will want to make sure to make the ground flat and compacted. To do this, you would strip the existing grass and then add in crushed granite. You will then want to compact this crushed granite layer. Once compacted, you would then be able to install our interlocking rubber tiles over that surface, creating your new patio.
