Frequently Asked Questions
1. How does WT255P improve concrete durability?
By reacting with water and cement particles, it creates non-soluble crystals that fill pores and capillaries, permanently sealing the concrete against water penetration and improving chemical resistance.
2. What projects have utilized this waterproofing technology?
It has been successfully used in large-scale infrastructure like the Hong Kong-Zhuhai-Macao Bridge, various metro system segments, and underground precast components.
3. Can I get a sample before placing a bulk order?
Yes, free samples are provided for testing purposes to ensure the admixture meets your specific project requirements.
4. What is the shelf life and storage requirement?
The product has a shelf life of 12 months when stored in original, unopened packaging at temperatures between 5°C and 30°C in a dry environment.
5. Is technical support available for mix optimization?
Yes, specialized laboratory support is available to help customers optimize mix proportions for high-strength concrete (C80/C100), ensuring both performance and cost-effectiveness.
6. Is the product environmentally safe?
Yes, the product is non-toxic, pollution-free, and non-radioactive, making it safe for both human health and the environment.
