Red dirt under tiles

Hi, We have just had the tiles taken up in the toilet and bathroom floor in preparation for a renovation but under the toilet tiles is a thick, rather earthy smelling red dust. Is this harmful or likely to cause problems with the re-laying of the new floor? The same dust/dirt wasn't under the bathroom floor which was tiled with the same tiles and presumably at the same time (1960's)
thanks

Hi Nat - it could just be a colour compound from the old tile adhesive, but there's always the concern that it's asbestos. We can't speculate about this - you should definitely call in an asbestos remover to get it tested.

 

Hope this helps,
