After more than a month of rainy season, most housing projects in Da Nang are facing the question of the level of leakage together with the treatment solution. Meeting this demand, Phuc Dat Dat Production and Trading Company Limited (Da Nang) said it is implementing a program to support people leaching with new materials: plastic composite film.
New solutions, new materials Mr. Pham Hoang Trung, director of Phuc Tat Dat Co., Ltd, said the support program will include free consultation for families on the cause of leakage in the works and discounts. Leaching treatment with new material.
“The reason we choose to use composite films in the prevention and treatment of seepage for buildings, are the technical elements of this material, which are good for meeting the sustainability requirements.” Mr. Trung emphasized so.
In fact, over the past years, Vietnam’s construction industry has mainly used two traditional waterproofing solutions: cement based products, including additives; And use bitumen film on the surface to be treated leaking waterproof.
Both solutions are cheap construction, convenient with the skilled builders.
However, waterproofing with cementitious materials during construction must be mixed with water so that the cementitious base can penetrate into the capillaries of the concrete, which coalesce there as a sealed knot to prevent invasion. Real of water. Therefore, in the long run, when the concrete is “hydrated” and shrink, water will still penetrate the capillaries. Cementitious materials are also susceptible to corrosion by chemicals, affecting reinforcement within buildings.
Bituminous membrane waterproofing solutions are also limited in life expectancy, due to the aging of the material when the temperature changes, adhesion to the concrete is not high, difficult to work on the edge of the eyelid, angular.
From that situation, Phuc Tat Dat Co., Ltd has cooperated with scientists and researchers to use composite film for waterproofing treatment.
This is a thermoplastic with a combination of additives to increase the adhesion to concrete, the technical name is WPC-C.
When applied, this solution only needs to combine plastic and glass fabric to strengthen the fabric, which will help reduce the absorption of heat and minimize cracking on the surface of concrete.
Waterproofing effect leaks
Mr. Trung described: “Our approach follows a rigorous process. After cleaning and drying the concrete surface, the moisture content of the concrete will be 10-15%, the worker will sweep the liquid WPC-C liquid onto the waterproofing surface, allowing the liquid resin to penetrate deeply into the concrete. Capillary capillaries. After a few hours, the plastic will solidify, sticking to the concrete capillaries, forming a strong film on the surface of the building.
Because it is plastic, hydrophobic in nature, this surface is absolutely resistant to water erosion. The shrinkage of the material is greater than that of the concrete, with a temperature of -30 to 100 degrees Celsius and many other corrosive chemicals. Therefore, the composite film will not cause cracked concrete or corrosion. .
Business practices show that from 2008 until now, Phuc Tat Dat Co., Ltd has implemented this waterproofing treatment solution in many big projects, such as Dung Quat Oil Refinery (Quang Ngai) Krong Pak water machine (Dak Lak), Sam Son FLC Resort (Thanh Hoa), Quy Nhon FLC (Binh Dinh) …
“These are the reasons for our confidence to bring about the effectiveness of waterproofing treatment for residential buildings in Danang from the rainy season, through the program that Phuc Dat Dat is implementing. . Companies and families wishing to participate in this program, please contact us by hotline: 0911.043579 “. Mr. Pham Hoang Trung emphasized so.
