Ice Rink Leveling? Answered
Looking for anyone's practical experience here. I have made backyard rink last 3-4 yr, now upgrade to Nice Rink liner. Holding water never a problem, many in Northeast last yr had limited time due to warm winter. My rink is triangle shape with legs 20x30. Slope on one side goes from 1" to 7" or so, average ice thickness is 3-4". Part of rink over brick patio block. Use wood 2x6-2x10 borders.
Was thinking of putting hay/straw under liner in the deep sections to reduce volume/depth so I can freeze solid and not have water layer under the ice. Or do you think the trapped air (under liner) will warm and work against this. I would think enough straw would not fully compress and help reduce water level, but then interface between liner and actual ground will have a lot of air space.
Got a few months to think on this, my season is late Dec-mid Feb.
