I have a raised bed garden with paths between beds that are 40" wide. What do I need to prepare the area for rubber flooring? I have already killed the grass and weeds with Round-up.

When installing our Regrind Rolls or any of our rubber flooring over dirt or grass, you will just want to make sure the surface is as level as possible. Other than that, a weed barrier can be added to ensure no weeds or grass grow between the rolls after they are installed.
