Concept and principle of water resistant concrete
Water-proof cement is a cement with a specific waterproofing representative included. Its major feature is to boost the density and impermeability of concrete by transforming the microstructure of concrete and minimizing the number and size of capillary pores. Typically, water-proof cement will certainly include water resistant products such as sodium silicate and potassium silicate throughout the manufacturing process. These products will form a water-insoluble crystal in the hydration reaction, filling the pores in the cement and making it water resistant.

Advantages and disadvantages of water-proof concrete
Advantages
Hassle-free construction: Using water-proof concrete is similar to that of normal cement, and no added expert skills are required.
Inexpensive: Compared with other premium water resistant materials, the price of waterproof concrete is extra budget-friendly and ideal for massive water resistant jobs.
Good durability: The water-proof cement layer, after proper construction, can maintain its waterproofness for a long time and is not easy to age.
Extensively used: Ideal for cellars, roofs, commodes, pool and various other scenes.
Disadvantages
Limitations: Water resistant cement is mainly made use of for light to moderate water infiltration issues. For severe water pressure and long-term immersion environments, the impact might not be just as good as professional water-proof coverings.
High construction needs: Building must be performed strictly according to the guidelines otherwise the expected result may not be achieved.
High maintenance demands: Once the water resistant layer is harmed, fixing is extra challenging.
