Aggressive factors from the environment (groundwater, wastewater, alum-contaminated water, salinity, ...) over time continuously attack the strength of the concrete tank, directly affecting the quality of the building. Especially in coastal or saline areas such as the Mekong Delta. Chlorine-induced local corrosion is the most dangerous factor that seriously affects the reinforcement, losing the bearing capacity of the reinforced concrete.
INSEE Extra Durable has a super-durable mechanism that helps to resist corrosive factors such as acids, sulfates, ... plus a super-dense structure that helps to prevent chlorine effectively, minimizing effects. environmental impact on the sustainability of concrete, increasing the life of the building.
