The Greens Encroachment Barrier System is an 8" deep piece of PVC pulled into the soil between the two turfgrass varieties. The top of the barrier track is a "tulip" shape. This provides a track for a special designed edging device to be pushed around the green. The barrier is pulled in to the ground in 100" sections and then spliced together.

The barrier is installed approximately 1/4" beneath the surface. (The 8-inch depth of the barrier blocks rhizome movement into the green and can act as a *wicking barrier between green rootzone material and the soil in the surrounds). Therefore, all subsurface encroachment (rhizomes) are stopped with no extra effort needed. The edging device when pushed around the green perimeter cuts all the above ground encroachment (stolons). These stolons are then vacuumed or blown up to avoid spreading onto the putting surface. The final result is minimal disruption and an aesthetically pleasing separation of the turfgrass.

The installation of the Greens Encroachment Barrier is contracted out to TRWait Enterprises Inc. only. Upon meeting the minimum requirements and approval of contract, barrier material will be ordered and an installation date will be confirmed. Prior to installation material will be shipped and a crew will be assigned to bring installation equipment to your location. TRWait Enterprises Inc. will request the use of some equipment, hand tools, and the use of at least three men from the existing golf course crew.

The installation schedule will be approximately four greens per day. The above schedule is based on cooperation of the golf course personnel and good weather.
