Can this be used in an open driveway?

You can use our Vented Grid-Loc Tiles in an open driveway. These tiles are very easy to install and maintain and are very durable being able to withstand the daily grind of a car being driven over them constantly. The only issues that you will run into are that these tiles are not very UV stable, so they may fade a bit in direct sunlight. With them being exposed to the elements, they will expand and contract more than if they were in a more controlled environment. Other than that, these tiles are great for this use.
