Ecological Building Materials
Description: RechSand flexible stone hanging plate – permeable bricks, easy installation, a great value product.
Eco Friendly Construction Materials
Properties: the use of sand in creating a “breathable and waterproof” Eco building materials. Comparing to clay, ceramic for decoration, the material is flexible, anti-slip, provides insulation, fire proofing, decorative and also sound proofing. Permeable bricks are great to be used in kitchen and bathroom because of its anti-slip character.
It is used at a library on its external wall as shown above.
Rechsand flexible stone composite insulation board built from the silica sand using adhesive and curing mold. It is flexible, light, weather-able, safe and a green product. It’s leading a new generation of interior and exterior decorative insulation materials.
The silica sand soft stone can withstand deformity but flexibility, with only about a quarter of the weight of the ceramic tiles which is easier to fall out of the attached walls. So, it can be widely used in commercial and civil buildings to provide better decoration and insulation. It is not only of great advantage but also renewable, Eco friendly construction materials. The material is strong, durability, colorful and rich in texture, less energy consumption during manufacturing, healthy and better for the environment. Easy to apply during construction, it is a great new alternative for the construction industry.
Permeable bricks are common, but few of us are paying attention to them. It can pay a big role in the municipal water conservancy project and can solve the city water logging problem, reduce dust, ease PM 2.5, etc., combining with the rainwater collection system to collect rain rain for irrigation, cleaning the streets, cars and so on.
1. The Origin of Permeable Bricks
The tiles are derived from a Dutch bricks invented by the Netherlands, and the Dutch bricks, also called buns, originated in the Netherlands. There is a 2 mm gap between the bricks for rain water to permeate into the ground.
The United States Shubulok company improved the Dutch brick and invented a brick body. When the brick body is filled with water it will be discharged into the ground, but the drainage speed is slow. It’s not effective during heavy rain.
In the nineties, the permeable brick was invented with permeable holes. With good permeability, the rain can flow from the tiny holes in the brick body into the ground with ease.
2005 at Rechsand, the use of its own technological advantages, as well as years of experience in the use of desert resources, developed Rechsand tiles made with sand. This brick is pretty in appearance, and the water penetration rate is fast. When the ground is covered with this brick, no laying of underground drainage pipes is required. Rechsand tiles are widely used in China’s municipal roads, squares and other places, including Water Cube, Chang’an Street, the Shanghai World Expo and many other large projects. We call them filter bricks.
2. The Classification of Permeable Bricks
From the point of view of the classification of permeable bricks, according to the principle of water can be divided into two categories, one is to rely on the surface of the brick hole through the water, one is in accordance with the gap between brick and brick through the water. The later type is more common.
With the continuous progress of technology, permeable bricks are also constantly being improved, common categories includes ordinary permeable bricks, polymer fiber reinforced concrete permeable bricks, composite concrete permeable bricks, colored stone composite concrete permeable bricks, oxygen permeable bricks, concrete permeable bricks and benevolent ecological sand permeable bricks.
3. Modern Permeable Bricks Advantages
- improve the growth conditions of ground plants.
- to a certain extent, adjustment to urban climate. Because the permeable bricks absorb two-thirds of their own volume of water, not only conserve water, but also inhibits pm 2.5.
- with a large area of permeable brick laying, easing the city municipal pipeline drainage pressure, reduce the city water logging.
- permeable bricks reduces rain water on the road and it won’t freeze as easily during winter season.
- permeable brick specifications and supporting facilities, these facilities can form a system to solve the city’s water logging problem, water shortages, water use problems and so on. At present, Rechsand provide a complete set of rainwater solutions.
4. Filter Bricks
Prices of bricks based on the technical content of tiles and materials used, construction cost and many other factors. Rechsand’s filter bricks are excellent in terms of performance and function, and the price is also reasonable. The overall value is much better than other types of permeable bricks.
