Ideal for existing underground water stoppage! Back-injection water stopping method using Alpha-Zol G.
We would like to introduce a construction method using "Alpha-Zol G," which enhances the durability and water-tightness of concrete structures and can effectively block water leaks. This method targets water leaks from multiple sources, such as honeycombing, construction joints, separators, and cracks, making it ideal for waterproofing existing underground structures. The waterproofing effect is stable over the long term, and the product complies with standards, ensuring safety. 【Features of the Method】 ■ The injection material identifies the source of the leak and stops it. ■ Excellent adhesion to wet concrete at leak points. ■ The materials (solvent-free) and method are safe for the surrounding environment and workers. ■ Superior resistance to seawater, acids, alkalis, and chemicals. ■ Provides stable waterproofing performance over the long term. ■ Partial construction is possible. *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Principle of the Construction Method** In underground concrete structures, water leakage causes (such as cracks, construction joints, separator marks, and joints) can lead to water seepage or dampness. This method involves drilling through the walls or floor concrete of the basement and injecting "Alpha-Zol-G" into the back surface of the structural concrete. By utilizing external soil pressure and water pressure, the injection material is allowed to permeate back through all leakage causes, including areas that have not yet experienced water ingress. This fills and seals the interior with the injection material while also forming a new waterproof layer on the back surface of the concrete (the rear side of the structure). *For more details, please refer to the PDF document or feel free to contact us.*
