The best base for an artificial putting green can depend on several factors such as the location, the intended use, and personal preference. Generally, there are two main options for the base of an artificial putting green: a compacted aggregate base or a concrete base.
A compacted aggregate base consists of a layer of crushed stone or gravel that is compacted and leveled to provide a stable and porous foundation for the artificial turf. This type of base is typically used in areas where the soil is unstable or has poor drainage.
A concrete base, on the other hand, is a more rigid option that provides a solid and permanent foundation for the artificial turf. This type of base is ideal for areas where the ground is prone to shifting or settling, or where heavy foot traffic is expected.
Ultimately, the best base for an artificial putting green will depend on your specific needs and budget. It is recommended to consult with a professional installer or landscaper to determine the best option for your particular situation.
