Cracked conncrete floor.
 
A friend of mine has a problem with his concrete floor. It has some large cracks in it, and it seems to be bulging upwards by about an inch in the centre. Does anyone know what may be the cause of this?

The footings or foundation could be sinking. The soild under the slab could be heaving. There could be several things going on.

How about some more information.:)

Is this a basement floor?
Is it a house on a slab?
Is it even a structure of any kind?
In what part of the country?
How old is the concrete?

You know...unimportant stuff like that!:)

The house was built in the 1950's in Dorset, England.
There is no basement. I would think that the house has normal foundations and the concrete floor sits on the ground. It is mainly in his lounge where the problem is.
Thanks for your help.

Well, one would have to consider soil content. What's the weather been like lately? How long has this been going on? Where's the water table? Does he/she have proper drainage away from the structure? Is there gutters and downspouts? I don't know anything about England's weather or building techniques.:) Just some things to think about.:)

A friend has suggested that the causes may be a sulphide attack. Does this sound like a possibility? If so what would be the next course of action.

According to this article, it should be easy to check if it's a Sulfate attack.
