cracks in slab ~ how long?

I have static cracks (surface cracks) in the slab of my 8 yr old home. Because of these we had cracks in the tiles and grout and after removing all of the cermaic in the house we can now see that the cracks have all made their way to the outer walls now. Should we expect more or has the slab settled all that it should?

Basically we are looking at putting more ceramic down and do not want the new stuff to have the same problem. Thanks.

First things first. Is one side of the crack higher than the other, or are both sides on plane with one another? How wide are these cracks? Are the cracks random or is there a pattern to them? Why are these cracks occuring, and do they still appear to be active (getting worse)?

They are probably 1/16" wide randomly located and both sides are at the same elevation. We are in south Louisiana and these cracks are very common due to the moisture content in the soil. My main question is...how long of a time period can I expect new ones to start or has the slab settled now? I will try to contact a local foundation company to see if they have a good idea. Thanks.

Slabs can take a very long time to fully cure, decades.

You would be a good candidate for Schluters Ditra membrane.

How much moisture do you got? Having too much moisture will effect a good installation as well. They sell moisture test kits, I forget the name, but it maybe a chloride test?!?!
