Can I use artificial turf on a sandy area?

I am not sure if I understand your question correctly, anyway, there are two possible scenarios here: installing artificial grass on top of the sandy area or installing artificial grass in an area that can be sandy. It is an easy answer yes if you live in an area that can be sandy with winds and etc., as long as you prepare the base correctly, it will be perfectly fine for sand to get on the artificial grass. If you are referring to if you can install artificial grass on a sandy base, the answer is NO. The artificial grass will be as good as its base: the base preparation is very critical for a good installation. Sandy base will be too loose and not solid enough for artificial grass, if artificial grass is installed over sandy area, you will very possibly see wrinkles, ripples, waves and dents on the grass surface, such issues not only destroy the appearance of the lawn, but also present tripping hazards. Even in a sandy area you still can install artificial grass by properly following our installation guidelines, you just can’t simply put artificial turf on top of sandy surface.
