You can install our Launch Turf Rolls in a garage gym. You can park a car on these turf rolls, but due to the weight of the vehicle, you may see where the car is parked after it is moved. This can be fixed by brushing it with a broom. To add more comfort to our Launch Turf Rolls, we would recommend adding out Gym Turf Pad under the turf for added bounce and comfort. Keeping this turf clean can be a little tricky as some dirt and debris may get caught in the turf, but with a power washer or hose handy, you would be able to remove any stuck on dirt and debris. For larger debris, you can just use a leave blower to remove it.
