    fiberglass pool crack

    My wife told me just the other day that there was a crack in our Viking Fiberglass pool. She noticed it while swimming. I didn't believe her, I had to jump in and see it for myself. Well, at least it's not leaking. That didn't last long. It's leaking like crazy now.

    The most frustrating thing to me is that this is the whole reason why we went with Fiberglass in the first place is that soil in South Texas shifts. A LOT. Almost everyone here has foundation problems with cracking, etc. So why in the world would I build a gunite pool here? Concrete cracks. That's what it does. Like I said, especially here.

    We thought Fiberglass would be more forgiving, flex a bit more,etc. Pool is only a year old.

    Yes, warranty claim has been submitted, etc. but has anyone else have this problem? I thought Fiberglass was almost impervious to cracking and leaking barring severe circumstances (of which we have none, except for hot and dry, but it's like that here all of the time).

    BTW, leak is on shallow end right in the corner between the floor and the wall

    oh darn. oh darn oh darn oh darn!

    I wonder if it was less a problem with your soil but instead a weak point of backfilling under that corner?

    Yeah, I would bet money on this. The guys that installed our pool were absolute clowns who clearly did not know what they were doing. Was horrible to watch. And this is our second crack by the way. The first one happened due to flooding of the shell by a huge amount of rain before it was completely set.

    Believe it or not, it was easy (ish) because the pool had half floated out of the hole. So they just moved it out of the hole completely and then repaired it from the inside and the outside. And then put it back in the hole and re-set it. The patch looks horrible, but it works so far

    Fiberglass pools are very sensitive to cracking if not installed properly

    Re: fiberglass pool crack

    Some of our members (oh Danny, where are you....) have had problems with expansive soils. They have installed micro-irrigation systems to help even out changes in soil moisture and reduce the expansion/contraction of the soil...it may be worth looking into to avoid future cracking.

    Re: fiberglass pool crack

    Yes, indeed, expansive soils must have moisture levels maintained at all times. We have black clay soil and it expands a lot when wet and contracts like crazy when it dries out. Our pool has move and cracked a couple of times. One side moved up about 3/8" for a while. I got a micro-irrigation system from Lowes and a hose timer and run it 3 times a day for 10 to 30 minutes and it works like a charm.

    Re: fiberglass pool crack

    Hi JPelizza, I am from Upstate NY as well, just north of Syracuse. We used Royal Fiberglass Pools from Tully NY. They did a great job on ours, and I really believe Jason knows how to properly install a fiberglass pool. We have had no issues with it at all, and its about 4 years old now. I have found that maintaining the pool is very easy, especially after I found this site! If you are considering a fiberglass pool, I would highly recommend them!
    Upstate/Central New York. Roman style IG fiberglass pool, 13X33, 8800 gallons, installed July 2012. Pentair cartridge filter, 1 hp Pentair single speed pump. Taylor K2006 Test kit. Went BBB route in spring of 2013, no problems, no regrets!!!!!!
