Water Pressure and Pool Repair

05/15/2012 12:49 PM

I have a hole 2" long x 7/8" wide in the 1/8" thick galvanized metal wall of our pool. The 20 mil thick liner is bulged but NOT torn yet....it looks like it can go any time.

Aside from draining the whole thing and patching, what could I use on the OUTSIDE to hold the water in case the metal punches through the inside liner.

If the metal cuts through the liner, I want to be able to hopefully STOP the water from rushing through the hole by putting some kind of patch on the OUTSIDE.

Any suggestions????

Suggestions? How about asking your kid to stop ramming his head into the sidewall!

Get some construction adhesive and piece of aluminum sheet, and sandpaper....Sand the surface around the hole and the aluminum piece of sheet, apply construction adhesive around hole and press patch sheet in place...apply duct tape to hold patch in place, or suitable brace setup....Apply vinyl patch on interior when/if possible...

Just get some underwater patch kits and layer them on the inside to re-inforce the existing vinyl.

I'd use my finger or something, and pack some fiberglass insulation through the hole from the outside, building up a thick enough layer to separate the liner from the metal.............probably about an inch. Then I'd use some needle nose plyers to bend the metal back out smooth. After that, you could just patch the metal with some JB Weld and touch up the paint. The fiberglass packing would leave a slight lump on the inside liner, but I don't think it would hurt anything.

Thank you all .

All good ideas to look at. I was concernaed about water pressure pushing too hard on the liner, but it seems to be holding enough for me to maybe get a stuffing in there and then pull the metal straight. Meanwhile adding to the liner from inside and gluing a patch with that adhesive should do.

* Kids are all grown and moved. Damage was my fault. I hit an old pair of Weiss tin snips hiding in the grass and they flew like shrapnel! Its a dang shame when you have to blame yourself.

Grandkids are eating this up because I am always b!tching at them to pick up their toys in the yard. Pliers were indeed mine .

Thank you all again.

The hole looks like it is small enough so you might be able to put a plumber's helper on the inside, then apply suction to pull the bubble back inside the pool while someone else makes the patch on the outside. Maybe even insert a thin plate through the hole which will then lay flat to seal the hole; with a dab of epoxy to help hold it in place.

Another thought was to make a temporary cofferdam so you can drain the water from the immediate region of the hole and make the fix.

Thank you for that suggestion. If the other fixes fail, that is certainly an idea worth looking at.

From your photo, it looks like the crack is just the first of several to come.

Whatever you do to the crack will probably not be enough until you empty the pool and make thorough and complete repairs, or simply replace it entirely, before somebody gets hurt when the wall crack ''opens'' completely...

I agree with Mr Guest in this case.

I've seen what can happen when an above ground pool lets go. My parents neighbor had an above ground pool that just burst with no warning. The water blew thru the garage door & picked up both cars that were parked inside and slammed the into each other and the wall. Luckily the neighbors home owners insurance covered the damage to the cars and garage and the neighbors and my parents are still friends.

Image what would have happened if it gave way while someone was in the pool.

slide a piece of heavy flexible plastic just wide enough to fit through the large dimension, and long enough to overlap the long dimension when turned ninety degrees. Use the plunger to suck the pool liner out while you do.

You don't say how far down the pool the hole is but build a small box from the surface of the water to under your hole. Seal it on the inside and drain the water (coffer dam if you will). You now have a hole with only air on each side. Fix with a will.

If you take a heavy piece of steel plate, drill a hole in it and add a stiff but still flexible tube that will reach upwards into the air from that hole, put some draught excluder, rubber seal around it to seal or use silicone.

Place over the hole on the inside, make a vacuum on the tube and "suck" the liner back into place (if it does not return of its own accord as I think it will) before doing a proper repair from the outside.

I also have to say it looks like damaged concrete and not steel plate in your foto.......

It's amazing that the pool got chinked like that and the liner survived the hit.

The steel walling is in no danger of collapse. The hole is not progressing and yes, that 20mil vinyl liner is holding firm.

I stuffed filling into the hole and pushed it around the liner so i could get a grip on the bent metal.

...pulled the pieces back out with a blunt nosed needle pliers.

...used a high powered contact adhesive to bond a piece of

3/32" galvanized sheet over the hole.

...overlayed the whole mess with a 3 layers of vinyl tarp repair tape

The one thing I have learned since my wife bought this thing back in 2002, was that ; POOLS ARE SOMETHING YOUR NEIGHBOR SHOULD HAVE!

Thank you all for the suggestions. As you can see, I used some of them and its all ce' cest' bon........

I have one available to anybody who thinks they want one. You'll have to fill the hole in after you take it.

Auto supply shops usually sell something called a fiberglas wet patch. The stuff is sold as a malleable sheet in clear packaging. You open the package and slap it on and let it cure. You can accelerate the cure with a heat gun.
