Advice needed, noticed some grout that was cracked and tiles becoming loose in our en suite wet room (water came up at edges when pressed after use). Was installed around 3-4 years ago at best guess by previous owners. Planned to clear out the grout and re set the loose tiles with new grouting where it had failed.
When I have done this and lifted one out seems to have taken some substrate out as well that I can't identify. Is the black stuff with mesh in the tanking layer? Doesn't look like any of the membranes I have seen on instruction videos. The blueish stuff feels a bit rubbery so wonder if this is the tanking?
Any ideas or have seen this type of system before?
