Fix Hollow Tiles - How to fix hollow tiles

[Dan]

What options have you used when it comes to fixing hollow tiles?

Is there something you can inject at all? Perhaps when underfloor heating has been commissioned a little too early and only a few tiles have suffered?
Or would you just recommend a rip out and fresh start, just to be safe?

There is a resin that can be pumped in, there's a YouTube video IIRC. Have you lifted one to see why they sound hollow?

The proper job is to replace..

I'd wanna be replacing to be honest....

I have not found any easily available resins in the uk although they are billable Finn Germany and holland. I think a call to Forbo Flooring or Eurocol (same company) might yield results. This is a topic I have discussed professionally for some time as it would save a huge amount of grief for customers who have anhydrite screed failures due to moisture or to poor prep or just plain ignorance....
