When choosing how you want the base of your green to be constructed, there are multiple options.
Current Floor System: Most basements floors are slightly uneven. If this is the case in your basement, this is the least expensive option. With this system we can install regulation cups. These cups will require coring through the cement floor or if you choose we can use shorter cups which only require coring a minimum of 2.5″.
Modular Base System: This system will allow us to add undulation using pre-shaped styrofoam under the modular base or custom concrete contouring.
Gravel Base System: This system will allow us to create the most realistic undulation and will allow us to use regulations cups or 4″ deep plastic cups. The gravel base is 6″ deep and may require a 4 to 8″ high paver wall stone border.
