Broken up asphalt floor to be tiled??

[waggy]

Hi Guys
Ive not been on for a while! But have a problem with a job a job that I have started today. The customer took the existing tiles up of the asphalt floor, and about 1 1/2 SQ M of the asphalt has come up with the tiles. The asphalt is on top of a concrete screed which is perfectly solid and dry. I was thinking of leveling over the floor in that area to get it level. But I have been worried about the floor failing because where I do the leveling will be solid, and as you know the asphalt will be hollow which will create vibration when walked on. |Can anyone help and advise, as i was thinking of decoupling membrane or fibre reinforced leveler, to go over it all.:mad2:

Can you not lift it all..?

If some has allready come up and as you state sounding hollow..........

Take it up to save any problems later

Surely your issue is the same as blown plaster on a wall and you wouldn't tile on that would you?

Get rid of all loose areas before making good , IMO.

I'd be inclined to take it up. A sds hammer chisel will rattle through it ok

is there any reason that the floor had asphalt on it? eg damp problems ?
