The polymer self-adhesive waterproofing membrane, represented by MBP-P Pre-applied Waterproofing Membrane, can be effectively integrated with the post-poured concrete structure to prevent water flowing in between. It is a successful pre-applied waterproofing model in global civil engineering of last 3 decades.
1 The flexible waterproof layer bonding on post-poured waterproof concrete to against water migration together
2 The production and construction technology has been proved through widely international applications
3 Outstanding waterproof performance and unbelievable low leakage rate
4 Simplified structural design to save the cost and construction period
5 Can be installed under harsh conditions
MBP-P Polymer Self-adhesive Pre-applied Waterproofing Membrane (hereinafter referred to as "MBP-P Pre-applied Waterproofing Membrane") is composed of polymer sheet, polymer self-adhesive film and artificial granule protection layer. The membrane can firmly bond on the post-poured concrete to eliminate water migration. Even the weak point of the membrane appeared, the water will be locked at the certain point, neither easy to leakage nor has the chance to flowing between the waterproofing layer and post-poured concrete. For those structure cracks the leakage will not happen just as if the waterproofing membrane in good condition. In other words, the flexible waterproof layer will work together with rigid post-poured waterproof concrete.
The firmly bonding of MBP-P Pre-applied Waterproofing Membrane and post-poured concrete
Eight years ago, the research and development of MBP-P Pre-applied Waterproofing Membrane has completed the China pre-applied waterproofing technical system and greatly reduced the cost. As domestic project cases geometric growth, the product also has been widely used in more than 60 countries including United States, Germany, Israel, Australia, Singapore and India, etc. Besides civil engineering, we also have mega project waterproofing cases such as No.16 Bejing Subway, Israel S-N Arterial Traffic Tunnel, Hangzhou Subway, Ningbo Subway, JDZ Utility Tunnel (Jiangxi Province), LPS Utility Tunnel (Guizhou Province) and Haidong City Utility Tunnel (Qinghai Province), etc.
On July 4th, 2014, Beijing Zero Point Market Survey and Analysis Company and China National Building Waterproof Association jointly released the "2013 National Construction Leakage Survey Project Report". Among the 1777 basements randomly surveyed in 28 cities, 57.5% (1022) had obvious leakage. In contrast, from the current construction project using MBP-P Pre-applied Waterproofing Membrane, no obvious leakage was found in the corresponding part, and the slight local water leakage rate was also less than 1%.
Because of the reliable bonding between the pre-applied membrane and post-poured concrete, contractors can skip fine aggregate concrete layer and additional layer. The pre-applied system has low requirement to the substrate so they can also cancel the screed. Traditional below-grade waterproofing requires two layers of bitumen membrane to reach top level waterproof, while MBP-P Pre-applied Waterproofing Membrane only need one layer. These advantages can greatly save the cost and construction period.
MBP-P Pre-applied Waterproofing Membrane can provide superior lapping property even in the water, to adapt rainy season and in water application. It improves the construction convenience and reduces the construction period and reliance of environment, but the quality can still be guaranteed.
In recent years, the MBP-P Pre-applied Waterproofing Membrane get more and more attention form railway construction contractors, and they began to use the material in bored tunnel of subway projects. Through our R&D and technical stuff repeated improvement and verification on jobsite, we can guarantee the membrane’s principle is clear, the application technology is complete and waterproofing effect is outstanding. Besides, we also provide MPU Waterproofing Coating, Likfix Waterproofing Coating.
