About 3 months ago I installed a shower tray (Pearlstone resin) onto a concrete floor. It was laid on a 5:1 mortar mix (About 10-15mm) and levelled. It was then left without the surround fitted for 3 months as the walls were not ready for tiling. It is in a corner and has been sealed with silicone against the wall as per the instructions. Today I have gone back to it and found the it has lifted by about 5mm on the edge that is away from the wall (it's an offset quadrant 1200x900). It's as though the tray has warped. It flexes back if you put weight on it but obviously is not stuck to the mortar although it feels well supported if you do stand on it and bend it back. The edges against the wall seem fine but I guess the silicon is holding those in place. Can anyone please advise what I should do.
My thoughts are :
1. Leave it and tile / install the shower surround and hope the weight of the surround holds it down properly.
2. Try to stick down the lifting side with a grip fill type of product and weigh it down until dry.
3. Lift it right out and dig out the mortar bed and try again from scratch risking the same thing happening.
Thanks if you can help me.
