Concrete

[etrexny1]

Hi I am having a system put in what are the requirements for the cement that will be replaced?
They are replacing an existing system that is only a few years old and the concrete that was pored over the existing system (Done by another company with diff product) was apparently substandard as its cracking.

The concrete we use is a 3000psi mix.

Our minimum replacement thickness is 2 inches (this depends heavily on the job and the overall thickness of the floor.)

We strongly recommend a 30-day curing period. No dehumidifiers and no surface contact with water.

Does that answer your question?

Sure I guess. Shoud I expect a truck or could they get this type of cement with hand mix?

[JacobPM]

No need for a truck, we'd do it all by hand mixing.

The only time there would be a truck would be if a whole new concrete floor is being poured. We don't do that type of work. But we do arrange for our drains to be installed before new floors are poured.

Do you have a thin or thick floor?
