The best base for an artificial putting green depends on several factors, including the type of artificial turf being used, the climate, and the amount of foot traffic the green will receive.

Generally speaking, there are two types of bases commonly used for artificial putting greens: a compacted aggregate base and a dynamic base.

A compacted aggregate base consists of layers of crushed stone or gravel that are compacted to create a stable surface. This type of base is typically used for smaller putting greens or in areas with stable soil conditions.

A dynamic base, on the other hand, is made up of a combination of crushed stone or gravel and a porous layer of finely crushed stone or sand. This type of base is designed to provide better drainage and a more forgiving surface for golfers. Dynamic bases are often used in areas with unstable soil conditions or where heavy rainfall is common.

Ultimately, the best base for your artificial putting green will depend on your specific needs and the conditions in your area. It’s important to consult with a professional installer or landscaper who can help you choose the right base for your project.
