Radiant Floor Heat

A month ago I poured 1 1/2 inches of gypcrete over plastic tubing, stapled to a 3/4 inch plywood subfloor.

The floor has been warm for the month.

The gypcrete devepoled hairline cracks, in line with the tubing (more or less).

It still cracks--- or at least sounds like it!

I assume it is now just expansion/contraction noise and no longer noise/cracking due to drying of the gypcrete??

To: Owners of gypcrete floors--- do they continue to go POP!!!, and for how long?!

Thanks very much,

Rick

Ours has been popping for the 2 years we've been in the house and shows no sign of stopping. I assume it's expansion/contraction noise.
