As a result of the natural characteristic of stone material, decided stone material can produce all sorts of problems in its use, cause damage even this is concerned with material of stone material itself on the one hand, also be concerned with installation and use environment on the other hand.
We often see in a number of senior hotels and other large public places with its stone paved ground appears local or large area of damage such as cracks, broken, pulverized, holes and other phenomena, these phenomena are especially in the marble paved ground in the most common.But people cannot easily and simply to replace these damaged stone, on the one hand will cause material and artificial aspects of the greater loss, on the other hand owners are also very difficult to bear the closure of the replacement of stone and related losses.Therefore, it is very important to analyze the reasons for the damage of stone floor.
Causes of stone floor damage:
(1) the subsidence and tearing of the ground foundation lead to the ground stone cracking;
(2) external damage leads to ground stone damage;
(3) from the stone of the choice of marble paving ground left a legacy:
On the one hand because people choose stone material often consider only tonal, and do not consider the difference on marble and granite in weather resistance and wear resistance
Original imported stone, on the other hand, in the majority with marble, granite processing technology will not so advanced, and marble colors and styles in the majority with elegant, this makes the indoor use choose marble stone now become a kind of fashion, which is now one of the major causes of many problems of ground marble stone.
(4) natural defects of marble:
Some marble has more natural defects such as cracks, sand holes, porosity, intergrowth and so on, if these defects did not have a better repair and make up, so once laid on the ground by damp and some harmful pollution after it will take the lead in the defective parts of the lesions and damage and from this extension;
(5) humid environment:
The main composition of marble is carbonic acid, it will expand under the action of water, so the stone structure of the more relaxed parts will first burst, stay on the marble floor is a stone pit, the formation of this stone pit in the humid environment will continue to powder, make the surrounding stone of loose.
(6) wrong protection methods:
For a part of the owners and builders, although they are in the marble coating coating protective agent, but the shop on the ground or a problem.
On the one hand, the cracks and loose parts of the stone material have not been well repaired, and the back of the stone material will be damaged quickly due to the large water pressure caused by moisture.
On the other hand, although in the marble front also made protection but the moisture on the ground also can follow the crack of stone material and loose place enter stone material interior to make stone material humidity increases, form vicious circle from this.
(7) wear has damaged the luster of the marble floor:
The hardness of marble is lower, strength is poorer, because this marble ground especially the position with more pedestrian can lose burnish to wait like before corridor, vestibule, counter very quickly.
