Cracks in cement-based floors are a common quality problem in floor construction. They not only affect the overall appearance of the project, but also reduce its impermeability and frost resistance, leading to corrosion of steel reinforcement, impacting the durability of the structure and causing problems such as water leakage. Later, rolling and compaction during use can further widen the cracks, causing extensive damage to the floor and compromising its functionality. After years of hard work by our engineers and researchers, we have developed the BANDě Cement Crack Sealer (Self-Healing Type), which effectively addresses this problem. This product utilizes a bionic self-healing method, forming an intelligent, bionic self-healing neural network system within the cement-based product. It is simple and practical.
