Was wondering how much weight a residential sub floor can hold. Would decking it with two sheets of 3/4 inch plywood to give an inch and a half plus the weight of ceramic tile be two much of a load on the floor hoists (2 x 10 at 16 inches)?
What I did was put electrical heat under part of the kitchen floor plus the concrete to cover the wiring has built the area where the heat is about an inch and a quarter above the rest of the floor. Now I have to deck it with more plywood to even it out. Just starting to wonder if I am making the kitchen floor plus all appliances to heavy.
It might be easier to rip out the smaller area where I put the heat and start over without the heat wires and concrete covering.
How much load can a kitchen floor safely hold?
