terry just because it hasnt failed for 12 years doesnt mean every installation will be the same,ive seen some chipbord tiled onto and its been fine but ive also seen a lot more of jobs where the tiles have literally fallen off.
i advise customers that we shouldnt tile onto it as the risk is much greater,i have tiled a chipboard floor once using a high spec adhesive and grout and it worked but its not something i would do again
