Hiya,
I've had some Marmox 20mm insulation boards laid down on my conservatory floor today using Bal PTB Flexible adhesive, as I'm planning on installing some under tile heating also.
The boards were laid down by a guy who does tiling, so I left it in his hands, however on checking the boards later this evening, by tapping them, there appears to be alot of hollow sounds, more so than solid sounds (which is where the adhesive is making contact with the boards) there's also some minor flex in the boards around the perimeter of the room which also sound hollowish when tapped.
Am I being paranoid here or does this mean that the boards have not gone down properly? As I realise that the boards are not designed for point loads, flex etc.
The floor was very slightly uneven, but I thought with using the PTB Adhesive, this would eliminate any problems.
Your thoughts would be very appreciated.
