Installation our cup and flag kit is very simple and typically done by the consumer. Typical installation the cup is as follows:
Grading and compaction of sub-grade materials
Grading and compaction of sub-grade materials are very important for the rolling of the golf ball. I recommend placing either chat or decomposed granite below the putting green surface. When the grading is complete, the underlying surface should be equally smooth without any compactor lines or small holes. If the subgrade materials are not smooth, the golfer will complain about irregular “Ball roll”. It is especially important that the area around the putting green cup be consistent.
If you are going to use type II or road base as your grading materials, I recommend placing 1 inch of chat or decomposed granite on top and compact to complete a smooth surface. Type II and road base has too much aggregate (rock) and will cause problems with proper “ball roll”.
When the grading and compaction of the subgrade materials are complete, take a level and check the 3’ radius around where the cup is to be placed to make sure it is flat without any imperfections. The 3’ radius around the putting green cup is very important to be flat, smooth and true. This where the golf ball will need your grading talents to simulate real play without the golf ball stopping or curving away from the hole due to improper grading.
Excavation of the hole
Many synthetic turf contractors place the putting green cups in dirt and compact around the cup. I highly recommend placing putting green cups in concrete mortar. When placing putting green cups in compacted dirt the cups tend to shift due to loosening of the soils caused by rainwater, foot traffic, and excessive pulling the flag in and out of the cup. When the putting green cup is not stable it will allow the cup to move or settle which causes the flags to tilt and/or cause a “volcano effect” (picture below to the right). If this happens you will definitely be called back to remove and replace entire green.
Depending on the cup size, it is my recommendation that the excavation of the hole for embedding the cup should be a minimum of 2” around the exterior of the cups diameter. This will allow for the poured and placed concrete to wrap around the entire cup. The hole should be excavated 1” deeper than the putting green cup height. When excavating the cup hole, I recommend placing weed barrier or a plastic bag to put the excavated soils on. This will prevent the excavated soils from disturbing the compacted subgrade surface.
Creating a film on the putting green cup and placing concrete around its perimeter will create a concrete cylinder which will allow the cup to rotate for height adjustment when the concrete mortar is cured.
I recommend two options for creating a film around the putting green cup. I recommend WD40/Silicone lubricant or Wax Paper to create a lubricated surface to allow the exterior putting green cup to be able to slide up and down after the poured and placed concrete cured.
- WAX PAPER – Take the putting green cup and place wax paper around its surface tightly.
- WD40/Silicone Lubricant – Take the putting green cup and spray the complete surface with WD40/Silicone Lubricant.
