After selecting the type of yarn used to manufacture the synthetic turf, perhaps the most important decision is preparing the base. Generally, there are three options to consider: straight concrete or asphalt, crush and compacted gravel, or an engineered structural base system.

Concrete will provide the most firm and smooth base; however, its drawback is it can be very expensive. The initial install can be costly and, once installed, there is not much leeway when it comes to relocating or removing the tee line.

Gravel is by far the most common subgrade used for synthetic turf tee line installations. It is effective, cheap, and easy to install. However, it has recently been discovered, when using a synthetic turf tee line with a low face weight, the gravel will eventually migrate into a washboard effect. Over time, the impact of the club head creates a slight depression in the subgrade. The next range ball will roll to the low spot and the golfer hits from there. This cycle continues until the depression becomes evident enough to the golfer. The golfer will then move the ball roughly 101 mm (4 in.) behind or in front of the depression and the cycle continues.
