Any advice?

I do not have much money. I want to build a second home. The first time I hired a team of builders and an architect who helped me in this. Now I am engaged in self-selection of material. I can not choose the best material for the foundation on wet ground. And how to do the calculations? Is there a formula?

This is a good decision, but now you have a big responsibility. I advise you to approach the case with great trepidation. The best material for you will be loam, read more about it on the Internet. Also, this calculator for calculating material. This creates accurate calculations and is quite comfortable to use. If you wanna ask anything - I’ll answer.
