In order to understand exactly which concrete is better to use, you should consult with any company that is engaged in the production and delivery of concrete, for example, this company works in MO. You will explain to them in detail for which building and foundation you need a foundation, and they will tell you which concrete is best to use and will naturally offer their options.

If I were you, I would choose a company for the delivery and production of concrete mixes on some site otzoviku, to be sure of the quality of their mixtures, that they bring all the time, that the company is reliable, etc.In my experience, by no means all such companies perform everything on time, and some even manage to do a bit of jiggling in mixtures.
