A. WHY WE MUST Waterproofing?
As we all know, one of the causes for the structure of the building was destroyed as water. This water can be rain water, water vapor in the air and groundwater. Typically, all building materials have all the capillary diameter from 20-40 microns and will absorb water through this capillary.
Rain water would quickly destroy the structure of the building, especially as structural metal tole roof, gutters, because the rain is acid, which acid is strongly corrosive metal.Water vapor is always present in the air with different rates depending on region or territory, weather. This ratio was very high in tropical areas in Vietnam so that these areas are very humid air. With the frequent impact of moisture on the structure(Girders, columns, walls ... and the other bearing structures) will eventually appear patches of mold, mold is growing very quickly and get into any kind of building material that is easy, and only after a short time was able to destroy the structures there.
We often see on the walls of the old works and new white mottling - that is harmful salts such as chloride groups, sulfate and nitrate. These salts have a very special characteristic is that they can even moisture in the air, then release the accumulated moisture out. When this process repeats several times to create the salt crystals.The combination of new crystals of salt crystals of salt will already have led to the destruction of the wall material, which is made with peeling plaster walls, plaster to build profitable, bricks and other objects other wall materials are also being destroyed.There were lots of traditional methods of moisture, but not actually deliver a perfect performance, ie, moist air is penetrating walls and other parts of the building (Vietnam Academy of Science has solved difficult problem).
Because the phenomenon of capillary water to the capillaries of the soil to absorb in the background, the concrete floor, floor after a time when reducing the load bearing effect dbong exfoliating regularly destroy surface ð floor.
B. DOT EVALUATION SITUATION IN VIETNAM
Technology and manufacturing waterproofing materials for the construction and development have formed a long world, but in Vietnam, this problem was not due attention. In the past when it comes to painting, we understand the simple material that is just to protect the metal surfaces, wood. but few who care paints used in construction. The use of waterproof materials to prevent leaking for civil, industrial fewer people interested again.But now, demand for materials and the waterproofing has been developed and selected. In addition to a protective effect, paint and waterproof to meet the beauty needs, contribute to the aesthetics of the facility. However, the type of waterproof paint and imported for use in projects in our country are very expensive and not suitable conditions for a tropical monsoon climate, specifications and construction in Vietnam, so most of the buildings were leaking penetration.
To address this, Research Center for Applied Science and Technology - Vietnam Institute of Science after many years of research has been formed for waterproofing product called Metco and Composite Construction Company Limited Nguyen Giap unit Exclusive use of this product.
C. Waterproofing METCO COMPOSITE MISSION
Metco includes six types of composite were applied to each object should be able to achieve effective waterproofing highest ·
Composite Metco - 1: Waterproofing for concrete and mortar application. Waterproof cases waterproof generation (higher elasticity) and water tank (not exclusive - certified by the Ministry of Health).
Composite Metco - 2: Waterproofing for steel and metal. Was used for waterproofing water tank (not exclusive - certified by the Ministry of Health). ·
Composite Metco - 3: Waterproofing for wood and other non-metallic materials. ·
Composite Metco - 4: Tram plaster cracks leaking water. ·
Composite Metco - 5: Used to bits instantaneous water spray holes are. ·
Composite Metco - 6: Used to reverse resistance.
Metco composite colloidal built with many advantages over those Vietnamese other waterproof, simple construction methods, non-toxic, colorful contribute to the aesthetics of the facility. Metco is a waterproof composite material of international standards but have cost Vietnam.
Co. Yuanjia collaboration with Research Center for Applied Science, and Technology - Vietnam Academy of Sciences made the waterproofing works like all the water treatment tank, and a roof under Thu Duc water plant, water plant water plant of Binh Tri Dong, cellars and warehouses of the company's wheat flour Pingtung.
We have a team of engineers, workers experienced professionals handle, waterproof construction for many years so we are professional in your field. Come with us because we are coming to with international technology and best service. Yours sincerely.
