We've had a quadrant shower tray fitted, wasn't expecting it to be so light! purchased from Plumbworld
The shower tray has been placed on a cement backer board which is on a suspended timber floor
A mortar bed was laid down for the shower tray to adhere to, however 24 hours later I have noticed there is a slight up and down movement of the tray. There is no sideways movement.
On closer inspection it appears some of the mortar has not bonded onto the shower tray.
What has caused this to occur?
The plumber has proposed to use expanding foam to ensure a secure bond which fill in any gaps
Would this be the right approach?
