This is not a question most of us can help with. I'll ask Waste to take a look, if he can. Meanwhile, posting pictures, via Flickr, Webshots, Picasa or Photobucket would help.

Welcome to The Forum, sorry I've missed answering this til now!
Spongy areas of vermiculite are an indication of groundwater flowing through or under itThose areas should be removed and new material troweled in (there are some other precautions you may want to take).
In the shallow end, you can either patch each little spot or do the entire floor - it's probably easier to do the 'spot patching'.
If you want more info on this, just ask and I'll try to get back more quickly.
Luv & Luk, Ted
