Principle and concept of water-proof concrete
Waterproof cement is a concrete with a specific waterproofing representative added. Its primary feature is to enhance the density and impermeability of concrete by altering the microstructure of cement and lowering the number and size of capillary pores. Normally, water resistant concrete will certainly add waterproof materials such as salt silicate and potassium silicate during the manufacturing procedure. These materials will create a water-insoluble crystal in the hydration reaction, loading the pores in the cement and making it water-proof.

Benefits and negative aspects of waterproof cement
Advantages
Hassle-free building and construction: Making use of water resistant cement is similar to that of normal concrete, and no added specialist skills are needed.
Low cost: Compared to various other premium waterproof materials, the rate of waterproof concrete is more budget-friendly and suitable for massive waterproof projects.
Good durability: The waterproof cement layer, after correct construction, can preserve its waterproofness for a long period of time and is not easy to age.
Widely used: Ideal for basements, roofing systems, toilets, pool and other scenes.
Drawbacks
Limitations: Water resistant concrete is generally utilized for light to modest water seepage troubles. For serious water pressure and lasting immersion environments, the effect may not be comparable to specialist waterproof finishings.
High building and construction requirements: Construction has to be carried out strictly in accordance with the instructions or else the anticipated effect might not be accomplished.
High maintenance requirements: Once the waterproof layer is damaged, repair service is much more complicated.
