ice rink

hey guy's i need to info. my father in-law to be asked me a question today about putting an ice rink in his back yard this winter. basically it a tarp like structure that get's flooded then freezes. some people he know have done this and say's it doen't hurt the grass. but we spend alot of time on his property so we want to make sure. i've seen it done but never say the aftermath. if anyone has any experiance or PROFFESIONAL comments please post them.. please hold off on the sarcasm i get enough off that at home lately.
thanks in advance

i've seen it done before, it leaves a low spot, and caused compaction pretty bad.

and these were only approx. 4" thick

if it's in an outta-the-way place, it would be pretty neat.

We had one growing up.

1.) You need a flat area. We had one that was our vollyball/badmitten court in our backyard.

2.) We used no tarp.

3.) We WAITED UNTIL THE GROUND FROZE (this is key) and then shoveled snow (this was the UN-fun part) around the whole thing to form a ridge around the perimeter. The rink had only 3-4" of snow left- just enough to cover the grass.

4.) We soaked the snow in the ridge so it would contain water and form a solid ring.

5.) We flooded the center in layers until it was smooth.

6.) In the spring, it just melted as any snow or ice would.

No damage to the grass and IMPO wouldn't cause damage IF the grass was dormant AND the ground frozen.

Compaction?! Doubt it: 4" of ice weighs the same as 4' of snow. I'm sure sub-soils make a difference, but by theory the soil would be no more compacted than a typical winter snow accululation.

No theory.

Depending on snow density (moisture content) it is +/- 10:1 ratio with water.

1 sqft. of water, 4" thick, has a weight of 20.80932 pounds. So if your rink was, lets say 30x40', and was 4" thick, the total weight of the ice rink would be +/- 24971 lbs.


Remember, the density of water is greater than the density of ice, so in actuality, when the rink is frozen it would have a thickness of roughly +/- 4.44", if it was confined to an exact 30x40" area.


Also Kent, water changes density at differant tempatures. At 15 degrees C it has a density of 0.9991026, but water at 30 degrees C has a density of 0.9956502. Ice also changes with differant varibles, but the same water sample turned to ice will
always take up about 1/9 more space than the same amount of water. Snow on the other hand would have to be compacted to 500Ncm2 to be equal to the same amount of ice at 1cm2.

Dochere,

While reading these posts one must stop to wonder,"why does a lawncare professional know these things?" Maybe you're just a misplaced rocket scientist! LOL

Dochere makes for intersting reading, but is kinda like DENNIS MILLER on Monday Night Football. (In other words guys, about 1/2% of his viewers can understand and appreciate him). I kinda like the mathematical potulates contained therein myself.
