All joists must extend at least 1-1/2" on to a bearing assembly, of either a beam or full height wall, unless metal hangers are installed to provide proper bearing support against other structural components. Beams, which support the floor joists over greater spans, are constructed in the form of laminated joists often referred to as built up beams, or one piece solid load bearing beams, cut from logs or manufactured. Electricians and plumber may often cut or drill into the joist work to install utilities, and this is accepted, so long as they do not remove more material than what is required by codes. This type of floor system is usually the cheapest to install.
Installing interlocking floor tiles is a much easier and user friendly process. They are designed to clip together, eliminating the need for measuring spaces and also leaving room for the tiles to settle. Each tile is surrounded with divots that lock to the other interlocking floor tiles. They clip together easily, much like a jigsaw puzzle, and allow a perfect seamless finish. If a mistake is made while installing the interlocking tiles, it is easy to fix. Simply pull them apart and start over. As no adhesive is generally used, they do not need to be pried up, risking damage to the floor.
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.
