#7 Green Sink Hole

We had a very unusual surprise this past week on the #7 green, a sink hole.

During the investigation of the sink hole we discovered an old terra cotta clay drain line under the subsurface of the current green. With all the recent rains occurring this year, water has been slowly finding its way into the clay pipe and removing the green’s sand mix While aerifing, the weight of the aerifier collapsed this area and gave us visual evidence of the problem.

Our staff was able to clog the clay pipe and apply concrete over the opening to stop the problem from happening again. The repaired area of the green was resodded and leveled out and the seams of the sod will heal in over the next couple of weeks.
