Hi... I called a few weeks ago and finally had a chance to look at the spa pads... question i have is what is the recommended type of prep work that needs to be done to the ground prior to placing the pad. besides being level, i'm assuming some type of gravel base would be needed. How thick and what size of gravel. thanks Ken

The manufacturer does suggest that some fine gravel or leveling sand can help make a level surface for the pads to sit on. The need for that would likely be based on how easy it is to level your natural dirt. On the "Features" tab, you will find a link to download the Handi Spa Pads manual. You can also click on the "Brochure" button for the same information.
