Laser leveling


Hi Wal, Roberta and all

An (amateur) video of laser leveling of the Jamberoo CC lawn 1 in January 2015 can be seen at: (just under 2 minutes long).

Unfortunately when the lawns were constructed they had a slope of about 0.6% (6 mm per metre) from east to west as well as a few hills and hollows so the programme has been to gradually minimise the slope and get rid of the hills and hollows by laser leveling every couple of years.  Commencing in 2010 we have laser leveled the No.1 lawn 4 times and have successfully removed the hills and valleys and reduced the slope to about 0.5% east to west (ie 5 mm in a metre).  Of course 5 mm in a metre equates to about 128 mm fall across the width of the lawn and, because there is a limit on the maximum thickness of top dressing of about 18 mm per leveling operation, it will take many years of leveling before the level can be reduced to below 0.2% (ie just enough for drainage.)
