High performance concrete+waterproof coating
Using high performance concrete and waterproof coating can effectively prevent tunnel leakage. High-performance concrete adopts high-efficiency water reducer and high-activity micro-mineral powder admixture, and has crack resistance and durability through reasonable mix parameters. Waterproof coating can provide double protection and make your tunnel safer.
Self-waterproofing of concrete lining structure
Using lining structure to waterproof concrete itself can improve the impermeability of concrete and reduce cracks. Adopting S8(0.8MPa) impermeability grade, it can easily meet all kinds of challenges. Use low hydration heat cement, high-quality ground fly ash and other active powders to make your tunnel more stable.
Deformation joint and maintenance work together.
Using deformation joints and curing can control longitudinal uneven settlement and prevent concrete cracking and shrinkage cracks. Add expansive waterproofing agent, superplasticizer, control cement dosage and water-binder ratio, and maintain measures such as roof water storage and side wall water spraying to make your tunnel more durable.
Elastic gasket+grouting double defense line
The double defense line of elastic gasket and grouting can effectively prevent tunnel leakage. Elastic gasket is a right-hand man for joint waterproofing. As the first line of defense, grouting provides long-term, homogeneous and stable waterproof function, making your tunnel watertight.
