The stone slab allows for robust and aesthetic developments. Depending on the selection criteria, it is possible to choose between two types of stone, natural stone and reconstituted stone.
Stone slabs, two types of stone
Choosing stone slabs for its terrace or balcony is opting for an aesthetic solution that will blend in with the decor. But in order to optimize your choice, you must take into account the characteristics of the stone slabs and see if they are suitable for your project. In the first place and before making a choice, you must know that there is two types of stone slabs, each with its own physiognomy. First of all natural stone slabs:
- they are composed of slate or lava stone like granite, and are therefore ecological,
- these slabs are cut in the mass. So they are irregular and do not have all the same color. By opting for natural stone you will have a unique pavement,
- their thickness makes them resistant,
- they are usually sold per square meter,
- laying, which is done with cement or glue, can be done in three ways. In Roman opus, where the slabs are offset between them, in opus in strip where the slabs are assembled edge against edge, and in not Japanese if one wishes to create an alley with the modern esthetics.
Then we also find reconstituted stone slabs:
- they are composed of a mixture of natural materials and mortars,
- this type of stone allows to imitate natural stone while being well less expensive. It is as robust as natural stone and the patina gives the impression that it has been cut in the mass,
- a vast choice of imitations is available with reconstituted stone: slate, granite, wood...
- as for natural stone, reconstituted stone is usually sold per square meter,
- the laying, simple, is done on a concrete floor or sanded soil.
Natural or reconstituted, what stone for slabs?
To make a choice between natural stone and reconstituted stone, consider the needs of the project, the tastes of the buyer and the budget allocated. In practice:
- natural stone benefits from a very long life and the passing years it will only beautify thanks to the patina. The tiling must be maintained with soapy water to prevent it from getting dirty. In spring it is still advisable to clean the stones to remove the residual moss,
- the reconstituted stone slab has the same durability and must be cleaned in the spring to eliminate moss. She will also skate over time. However, and unlike the natural, it is recommended to apply a water repellent treatment with a brush on each slab before putting them and this to prevent them from staining.
At the aesthetic level:
- natural stone will have an incomparable cachet and totally natural. It adapts to all styles, whether classic, rustic or modern,
- reconstituted stone offers an almost perfect imitation of natural stone. The rich range of possible imitations, with even some wood imitations, this stone seduces many users.
Finally the last criterion, undoubtedly one of the most determining, is the price. Indeed, there are significant differences between the two types of stone. The price of a tessellation in natural stones will depend on the supplier, the chosen stone... Overall, for a square meter of natural stone:
- the price will go from 35 to 70 euros for slate,
- granite will cost 70 to 180 euros according to the specificities of the stone,
- limestone, the square meter will cost 60 to 130 euros.
Reconstituted stone is much more accessible with a cost ranging from 20 to 60 euros depending on the finishes.
