Building on weak grounds and the settling of structures and concrete roads.

Yes, we have to come back to this. There is readily available all kinds of photos showing this situation that will be posted shortly.

See you soon.

We will come back to this very important section mainly applicable to cold climate. Return to Home Page from Foundations.
