what is the name of the item that attaches the base plate to the concrete floor
The first step when building a floor is to use a pressure treated 2Ã6 for the sill plate that will be bolted to the concrete foundation. This is what holds the floor to the foundation and keeps it from being blown over in a massive storm. This sill plate must be pressure treated lumber so it will not rot or succumb to pest because it directly touches the foundation of the house.
