Raw sheathing comes in 4`x8` sheets, most often installed as 3/4" thick plywood panels. This type of sheathing is adequate for spanning joist work spaced up to 24" apart. The sheathing is lain with the joints staggered in such a matter, that no two edge joints line up with adjoining sheets. It is very easy to install, requiring the least amount of labour. The sheets are fastened with either 1-1/2" flooring screws, or 2-1/2" nails, spaced about 8" apart. Although not required, it is a good idea to provide backers or supports under the joints, between sheets which run perpendicular to the framed floor assembly.
In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
Many people also have questions about the tiles durability and use. Interlocking floor tiles are usually placed on the floor underneath it, meaning there is no adhesive or floor base. Some may become concerned that the interlocking tiles will become loose easily due to the lack of adhesive. This is not the case. Tile floor systems are designed to lock together permanently. When appropriately installed, the interlocking floor tile should remain exactly as it was placed until the user decides to move it. Interlocking tile floors are appropriate for any use, from industrial to residential. This interlocking flooring system does not have as much risks compared to traditional tile flooring.
