Limestone Pavers

Introducing our durable and versatile Limestone Pavers. Made from natural limestone, these pavers offer a timeless and elegant look to any outdoor space. With their strength and easy maintenance, these pavers are the perfect choice for a long-lasting and beautiful walkway, patio, or pool deck.

According to a survey conducted by geologists in Guilin, it was found that the water there can dissolve and erode the limestone pavers surface about the thickness of a fingernail every year. Although it only dissolves so little every year, the history of the development of the earth is extremely long. Taking the most recent geological period-Quaternary, it is about 3 million years old. Even with such a slow rate of dissolution, 900 meters can be dissolved in 3 million years! The lonely peak of Guilin is only one or two hundred meters high, and the maximum height of common caves is only tens of meters. But it is not where limestone pavers can form such a landform. Instead, it requires a large area, large thickness, and pure geologically pure limestone, as well as warm and humid climatic conditions to be able to develop into such a perfect landform. Beautiful natural scenery.

limestone pavers is abbreviated as limestone. Common varieties include white sand beige, French limestone, French wood stone, Spanish white sandstone, Fontainebleau, etc. This series of stones is popular with people for its simple, solemn, elegant and natural decoration style. favorite.

We know that limestone is a kind of calcareous (calcium carbonate) sedimentary rock. Because this type of stone does not pay attention to crystallization and metamorphism, its texture is relatively loose, the density is small, the porosity is high, and the pore diameter of the capillary is large. It has a large water absorption rate (5%-15%), while the water absorption rate of other marbles (metamorphic rocks that focus on crystallization) is generally (0.2%-1.5%). It can be seen that their water absorption rate is about ten times different, and limestone Its physical strength is also low (compressive, flexural and surface strength), which are typical limestone pavers characteristics. It is these characteristics that determine that limestone products are easily polluted by daily pollutants such as smoke and dust in the atmosphere and colored pollutants (tea, juice, red wine, bath liquid) in the daily use environment. We often see that the newly renovated limestone slabs have been seriously polluted and turned into gray sandstone. It was recontaminated shortly after being refurbished and cleaned, thus failing to achieve the desired decorative effect. It can be seen that how to protect limestone well and improve the stain resistance of limestone is the key to the success or failure of limestone pavers decoration.

It can be seen that the key to solving the problem lies in how to effectively reduce the large pores of limestone. Here we have developed a kind of high solid content nano-scale water-soluble silica sol specifically for limestone wall cladding, called "limestone silicifier", after brushing and dipping on the surface of limestone wall cladding. It can penetrate into the pores of limestone, and after drying and solidification, it will form a network of silica gel crystals to fill the pores of limestone. The insolubility of the gel is stable and strong (better than the limestone itself), so it has a permanent filling and reinforcement effect, which greatly reduces the pore size of the limestone wall cladding and makes the surface more dense. The surface hardness is also greatly improved.
