The PCB is a translucent liquid that is innocuous and odorless,which makes it a high-tech enviroment-friendly product. A synthetic of multiple polymers with the rare-earth content,it can be mixed with the all kinds of cement mortar and concrete. It boasts of the great glutinosity, high anti-pull, anti-bend and anti-penetration performance. It is the most state-of-the-art waterproof agent and the adhesive agent linking the new-and-old cement, which fills the blank in China.

For users：
1 It can be used for the concrete girder, column and the foundation of the building. The appropriate amount for reference of the PCG to use is: 0.5% to 0.8% of the 　cement(kg) in one churn-up. 　　　　　　　　　　　　　　　　One to three barrels of PCG for one stere of concrete or cement mortar;

2、It can be used in the anti-penetration project for the exposed wall and the internal wall of the the building. The plastering layer is about one centimeter thick, and the appropriate amount for reference for 12 square meters is : (1) 50 kg of cement; (2 ) 125 kg of sand (3) 15 kg of water (4) 2.5 kg of the cement gel; (according to different situation, more cement gel could be added, 　but a corresponding amount of water equal to that of the extra cement gel will be dedcuted);
3、While being used in waterproof project of the roofing, no water should be added, and there should only be the PCG in the mixture of the cement and the sand；
4、While being used in the adhesion between the new and the old concrete，again， no water should be added，thre should be only the PCG in the mixture of the cement and the sand；
5、While mixed with the fast repair agent, the appropirate amound of the PCG to use is, for reference: fast repair agent: PCG= 1kg：0.30kg

Scope：
1、 The underground aerial denfense and the anti-penetration project for other underground constructions ；
2、 The roofing & floor anti-penetration project；
3、 The anti-penetration project for the cement-reveted pressure pipe and other cement and concrete objects;；
4、 The dam anti-penetration & repair project；
5、 The anti-penetration project for the foundation and the concrete structures of the building;
7、 The adhesion between the new & old concrete；the adhesion of cement mortar,　 concrete and marble, granite and 　　　ceramic tiles；
8、 The anti-penetration project for the highway, crossroads, airports and wharfs；
9、 The anti-penetration project for the internal wall and the exposed wall of all kinds of building;
10、The anti-penetration & waterproof project for the water storage tank.

For users：
1、The product could be directly sprayed on the leakage point；
2、When mixed with the cement, the ration of the LWA to the cement should be 1:50. First of all, churn the LWA well with an appropriate amount of water, and then blend in the cement and the silver sand for use. Under special circumstances, the ratio of the LWA and the cment could be 1:1.
