Excuse me, which is stronger in self-waterproofing of concrete structure?

Structural self-waterproofing is to solve the waterproof problem from the structure and achieve the same life as the building structure, which is called century-old structural self-waterproofing. The general design of underground waterproof concrete slab is C30 (strength grade: divided into four grades: C 15, C20, C25 and C30). There are C35P8, C40P8 and C45P 10 ordinary waterproof concrete, and the highest impermeability design is P 12. The original mixture ratio is different from that after adding Kolo inorganic nano-scale anti-cracking and anti-permeability agent. There is no need to make an external waterproof layer at all. Both underground waterproof effect and engineering waterproof durability are several times higher than traditional waterproof effect. Kolo self-waterproofing technology of concrete structure was used for waterproofing and moistureproof of military bunkers in the United States during World War II.
