Here's my issue (wish I had a picture, maybe try to post one later): I filled my rink in early Dec when we had a 4-5 day stretch of below freezing temps. My rink runs North/South. My depth ranges from 4" in the NE corner to 12-14" in the SW corner. The rink sits in an open area so the ice along the North boards is in direct sunlight all day (the ice along the South boards is shaded by the boards themsselves). Over the last month or so of these consistent 40+ temps, I've watched the ice creep slowly away from the North boards as it melts. Somewhere in the SW corner, under the thickest ice, I have a leak(s?). I'm guessing the constant pressure of the water under the slab of ice caused the liner to split. I do not like the idea of hacking through the thickest ice to try and patch the leak, especially since I may find more than one. Any attempt to replace the water I've lost in the North end results in the water running under the slab to the low area and out the leak.
Now that we look like we'll be having consistently low temps for a while, I'm thinking I could mix up a snow/water slush and use it like mortar to fill in the gap on the North boards. After that freezes I could then begin putting water down to build the ice back up on that end.
Anyone ever tried this before? Any success? Any other ideas?
