Laser-Tapered Resurfacing on a Har-Tru Clay Court 

I’ll try an answer. Iv been maintaining both sprinkler irrigation and subsurface courts for forty + years. It depends on how many tons per court. The court is built with forty tons, which when compacted, will work out to be 1” of surface. About regrading of three courts it could run you anywhere from $15,000 to $35,000. That’s a very rough estimate. This includes new tapes of course. I would call Har-Tru, inc for more info.
