What's the most common mistake you've seen in a new home construction?

We believe that the build-to-loan ratio should be 80/20% The reason for this is to leave the homeowner room to be free to make changes or upgrades to their home during construction.

Concrete requires time to harden & cure before the loads of the walls and floors are constructed. 30 to 60 days.

thanks for the info! @benjamind what sort of limitations or restrictions are there on what can be done won the foundation during this period?

[supremeremodeling]

The proper curing time and process is vital for the construction of the home. While full strength does not occur for 28 to 60 days, depending on the conditions.

Hi
As we mentioned, you can do work out side & inside the foundation, but not on top of the foundations. Do Not backfill around the foundation, pressure from the fill will bow the walls and cause cracks for water to seep through.
