Is it possible to install on a hard surface as concrete or tiles? Will the water passes thru?

You can install our Premium Putting Green Turf Rolls over concrete or tile. These turf rolls have been installed over these in both residential and commercial applications. Water will still pass through the turf to the subfloor below, but will then pool on the harder substrate. Over time, the water will evaporate or even got into the porous subfloor below, but it will not drain as it would if it were installed over dirt or crushed granite.
