Ceramic tiles
VS
Homogeneous tiles
•lower water absorption rate and higher density. •tougher tile compared to Ceramics tiles. •It's surface can be polished to make it reflective shine like those of a mirror. •it can be round edged at the sides, without showing a different material beneath the tile (Ceramic tiles are made of red clay with a thin layer of "coloring" on the surface. Chamfering the edges of the tile will reveal the red base below - PVC strips will be need to cover the edges of ceramic tiles) •Homogeneous tiles are generally 30 - 50% more expensive than Ceramic tiles, although polished homogeneous of bigger size may cost much more. •In an unlikely event of breakage due to fallen object, Homogenous will not leave a big crack line and it will not show a different material/ color beneath the surface. •Between these 2 materials, only Homogeneous tiles will be considered for the flooring of any commercial project, as Ceramic tiles will not be able to withstand the kind of load produced by high traffic of human flow.

Immediately after sanding, the finishing process should begin. This involves applying a protective coating and a colour, if desired, to the flooring. Finishing produces a uniformly enhanced surface and seals the wood to make it less absorbent to moisture and foreign materials.
FINISHES TO TIMBER FLOORING - staining (colour)
- sealer (fill up pores) - bleaching - wax finish
- Polyurethane - Melamine / acrylic

Timber Flooring defects - lifting Expansion of the timber due to uptake of moisture - failure to provide adequate damp-proofing membrane under the blocks.

Engineered wood
WOOD VENEER ON PLYWOOD
Each plank is made up of multiple layers of wood, each layer arranged in a cross-grained manner to give it dimensional stability. The cross-grain construction helps to lessen the effects caused when wood naturally expands and contracts due to temperature and humidity. While the top layer is real hardwood, the engineered components underneath make the flooring more stable, easier to install, and more environmentally friendly than traditional solid hardwood flooring. 125 mm wide X 10 mm thick (300-1200 mm L)
