Hi - my plumber has just installed a shower tray, and it would be very
difficult to remove. However, the tray is not very well supported.,
and flexes when stood on. It was supported with mortar, but only in a
few areas (for some reason), and these blobs of mortar have not stuck
in place so they can be pushed around with a stick...
However, I can get access with a hose to the cavity under the
fibreglass tray. Can anyone suggest some sort of filler I can pump
into the void, which will set hard enough to support the tray well?
I'm concerned standard expanding foram may not be up to the job...
