How do you Repair Cracks in In-ground Gunnite Pools in Utah?

Good question, and we’re glad you asked. There are a couple of options.

First of all cracks in in-ground gunnite pools don’t always leak and consequently you don’t always have to fix them. If you see a hairline crack it might not necessarily mean you have to fix them because they might not be leaking or leaking enough to matter.

If you do suspect the crack is leaking try one of these options:

1. Inject dye next to the crack and watch and see if the dye gets sucked into the crack.

2. A dye-free option is to clean the swimming pool, and then within a day or two check out the crack and see if dirt or debris to begin building up in the crack.

If you determine the crack is leaking you probably want to put an end to it. You have two options:

1. Calcium Ball: This is a DIY measure. A calcium ball is a mixture of cement and calcium mixed with enough water that you can form it to a ball. You’ll take the calcium ball and either reach under the water or get in the pool and rub it into the crack. This works because calcium makes cement set or “go off” very quickly. This often works and works well, but it’s likely you’ll eventually have another crack. It’s worth a try but not necessarily a long term solution. (This option is if you have a traditional white plaster pool)

2. The best way to fix a crack is to drain a pool, exposing the crack, and hire a professional (like us) who will take a diamond blade saw and cut the crack open two inches wide and two inches deep the length of the crack. We will then fill the bottom of the crack with an industrial grade caulking product and patch in the plaster 1-2 days later, after the caulking has cured. Doing that is a much more permanent way to fix the crack, although there are no guarantees because pools may still be settling.
