I was planning to install a Grohe wall hung toliet frame. The wall is built of thermalite blocks. Was going to attch it the Grohe frame brackets to the wall by fixing them with bolts set in a resin filled undercut hole. All set to go but the position of the bolt needs to be bang on the mortar layer between the blocks. Do I a) carry on as planned b) carry on with a resin system but with a slightly deeper hole undercutting slightly higher into the block above and below or c) need to find some other solution. I'd like to avoid bringing the frame out into the room further, eg by attachingit to a batten screwed to the wall.
Thanks
