How thick is the subfloor and what is it made of? In new construction. ¾ inch plywood or Oriented Strand Board is a standard subfloor over joists that are 16 inches on center apart. We find that is almost never enough to meet the deflection standards in most homes. Other times there is old plank flooring beneath a layer of plywood. This is a wild card. since the engineering tables usually don`t include the value for planks in their calculation. but common sense says it does add some stiffness.
Fine. but how do you know if your floor meets the L/360 standard? We face this in the field all the time. but in remodeling. there`s not always a clear answer. There are published tables for calculating deflection. (including a really cool online calculator at http://www.johnbridge.com/vbulletin/deflecto.pl ) but they assume you have full knowledge of how the floor was built. To be able to use the engineering tables. you`d need to know how far apart the joists are. the length of the unsupported span. how thick the joists are. what type of wood and in what condition the wood is in. as well as how thick the plywood is. if any. Realistically. if all of this flooring is hidden by finished ceilings below and covered over by old flooring layers above. educated guessing takes center stage. The following questions help to determine floor stiffness using common sense guidelines
This article talks about garage tile flooring and the advantages and disadvantages you should consider before installing it in your garage. Tiles date back to the middle ages and have always been a popular flooring option. From the simple to the ornate choices are virtually limitless and you can have a field day choosing your tiles.
What`s the property owner`s risk tolerance? Does he/she want to be rock solid sure of the stability of the floor? Even if that means spending extra money and/or time to reinforce the floor. and accepting a floor that may sit higher than surrounding floors? Or is some risk of failure acceptable if the floor is not built to the righteous standards of the TCNA? Sometimes the extra effort is not worth the cost to the property owner. who should be fully informed on all options. Contractors who install flooring shouldn`t assume that clients don`t care enough to solve the problem: in the last year we`ve had two clients who spend thousands of extra dollars to reinforce subfloors in a kitchen and laundry room when we explained that their floors were too unstable for tile. They really wanted tile. and were willing to make the subfloor ready for it. even if it cost more.
