We get asked all the time about what is the ideal base on which to install synthetic ice. In short, the ideal base is a poured concrete base. It is not going anywhere for a very long time.
But, that is not always practical or affordable as an option. Other bases we have worked with are asphalt, wooden platforms, grass, synthetic grass, compacted stone, compacted earth, and even sand.
To be honest – sand works as a great base, if you know what you are doing. We recently installed a good size SmartRink on top of a smooth rolled volleyball sand court. Once the base was flattened and rolled smooth we placed a 6mil vapor barrier sheet on top of that and taped the seams together. From there the trick is to work from the product side as you go row by row so as not to disturb the sand with footprints.
Once a few rows are in place the work can go quickly as if you were installing on a concrete base. We installed using ProFast-10 panels that feature a patented and unique Hybrid-Lock (TM) joint that will lock into place and hold the panel joint both horizontally AND vertically. This uniquely machined joint ensures no vertical movement from panel to panel. Once everything is locked down in place the sand base is completely solid.
The images within this post show the process. We do not recommend sand as a permanent long term base solution – but for a seasonal rink and the right panel joint system such as the SmartRink ProFast-10 panel, then it will work just great and save you from having to buy an expensive sub-base such as plywood or engineered foam cell products.
