Today there are more and more summer residents and owners of country houses use paving slabs for arrangement of sites. It spread platforms for cars, arrange paths and also pave entrances and the yards. Such covering in comparison with asphalt concrete maintains temperature differences better, differs on color and form and if necessary can be dismantled, and then is established on the former place.
Instruction
1. Consider that the good paving slabs cannot cost little. For example, for production of square meter of color tile about 0.5 kg of coloring pigment are used. Only one this component costs about 10 dollars for kilogram. And use of the special modern equipment and other components of concrete mix have the price too. The low cost of product demonstrates use of low-grade materials and, perhaps, about neglect norms of specifications.
2. Notice that the smooth surface of tile not always demonstrates its goodness. Specify by what way gloss is reached. It is good if it is received by means of introduction to concrete mix of special additives, and it is bad if the smoothness is reached by increase in amount of water. The last will have an adverse effect on tile durability.
3. To understand, surface of smoothness, what of ways of giving, has been used, take two products and slightly hit them the friend in the friend. If you hear the ringing sound, the tile is made according to all rules with use of quality materials. The deaf sound testifies to glut of product water or use of low-quality materials.
4. Look at the saturation of color of tile. The bright color can be reached by addition of expensive pigments that by all means affects the price, or overdose of normal dyes, and it significantly reduces not only the price, but also tile durability.
5. Find out what material has been taken as basis. The paving slabs at which production clay sand was used will serve only a few years. As clay and cement – materials incompatible, such tile will collapse under the influence of frost and moisture. About availability in tile of clay yellow spots on its reverse side signal.
6. Ask one tile exposed as an example and split it. Qualitative product inside uniform, without time and emptiness. The color tile has to be painted completely over in all thickness. The product at which only the external layer is painted is not durable. Pigments weaken concrete which is stratified.
