There are three main types of sub-flooring installed to cover and span the floor structure. It is over this that the finished floor will be placed. The sub-flooring types include raw sheathing, interlocking and strip. It is utilized not only to provide a surface for the interior finishes to be placed on, but also to prevent twisting or torque forces placed on the building. The sub-floor also allows load sharing within the joist framing system. Often the sub-flooring is glued to the joist work to eliminate creaking floors and to prevent the floor joists from turning.
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.
One drawback is that this type of floor requires special hanger systems designed for the joists, to enable them to be hung from each other or against beams/bearing walls. Manufactured joists are becoming a popular flooring system, for they are relatively cheap, reduce labour time and provide adequate support. However, builders need to familiarize themselves with its installations, for poor installation can cause severe structural damage to the joists. A good example is a three point, center bearing joist, left with the top chord uncut, which can potentially fail or pull apart, over the center bearing point.
Traditional tile installation requires many tools and lots of patience which have to be pre-set on the floor, cut down to size, then adhered to the floor using a strong industrial glue. They will not stick to every surface and frequently, a layer of floor base must be installed before the tiling work can begin. If the tiles are placed too close together, they can buckle, leaving unsightly bumps and lumps on the floor. If they are placed too far apart, there will be obvious gaps. If a mistake is made when laying down the tile, it is very difficult to fix as the tile is glued to the floor. The tile will have to be pried up, excess adhesive scraped, and the process started over. Laying traditional tile floors is a project that can take several days, to several weeks, to finish.
