Gunnite Problems

[mshumack]

Gunite is just cement without the stone (aggregate). It sounds like the gunite in this area was improperly mixed when initially installed. Patch it an don't worry about it - but check the rest of the pool for hollow spots while your in there. Hopefully it was just this one area.

Thanks Mschumack.

We've had a couple of core samples taken and it looks like it is poor quality gunnite and is isolated to about 1/3 of the pool. The gunnite appears to be in two layers (two applications?), the bottom one is fine, it's the upper one that is bad.

We're going to have the plaster removed from the problem area and the bad gunnite repaired.

Removing the plaster to inspect and address the gunite platform is your best avenue.
I wouldn't sweat this at all, I'm sure that your contractor has dealt with situations like yours before.

See Ya,
