I am pretty sure it has been laid upside down so tilies will need taking up and old mat , check to see if any movement in ply re mat and tile

Taken from the Genesis instaltion sheet
Installation
1. Substrate:
The substrate must be stable, level and free of loose material. Before installation, the GMAT mats are cut to the
required dimensions. Thin bed mortar or fluidised bed mortar is applied to the substrate using a 4 x 4 mm serrated
trowel. The tile adhesive must be matched to the substrate. Best results are usually achieved with hydraulically
bonding thin bed mortar, flex mortar or fluidised bed mortar.
Recommendations for ideally matched products can be obtained directly from Genesis.
2. Installation:
Then the mats, with their woven carrier fleece facing downwards, are pressed into place and hammered flat. The thin
bed mortar must form a strong mechanical bond with the carrier fleece under the GMAT mat. The mats must be laid in
the thin bed mortar within the setting time of the adhesive. Access crawl boards should be used to prevent damage to
the mats during installation.

I have just looked at the pics, the mat has been laid the right way up. I had a problem with a Genesis mat not long ago, I cut through the mat 1m2 and ripped it up, the genesis rep was a witness. It seperated exactly like the pictures, the rep told me this is just what should happen. The fleece stayed anchored to the floor, the top just peeled off clean. Sorry this doesn't shed any light on the problem.

So there is fleece on one side and mesh on the other ?. Looking at the pictures on the PDF it shows that the product has been installed correctly but looking at the photos on here it shows no fleece unless this was removed with the tile and G Mat ??

The fleece is still down Neale, you can see the imprint of the top layer. Just the same as mine, the rep said this is normal.

Hi Phil,

It is a while since I checked in on this post due to general hectic, and we are still wrangling with various parties about who is responsible. I am assuming that when you laid your problem mat you observed all the standards in terms of subfloor preparation? A concern I have is that as the plywood is only 9mm that this could be a contributory factor even though it is pretty solid on the boards, and one that Genesis have cited as they have visited site now. Although to be fair to Genesis they are not just walking away from the problem, and are trying to be helpful, but they have not admitted full liability either.

What did you do to rectfiy the situation?
