Leakages in concrete structures or infrastructures are generally overlooked as minor problems in the field of construction, but as of recently, leaking in concrete structures and infrastructure have become more emphasized as a social problem. In addition to the reduction of property asset values and hygienic problems, continued leakage can cause a significant reduction of structural durability. In extreme cases of negligence in maintenance, large infrastructures can collapse. For many types of existing concrete structures, some form of water is always present, so waterproofing must be properly installed to ensure the safety, durability, and functionality of the structure. In concrete engineering, high-quality watertight concrete is often used to prevent leakage, and waterproof engineering employs the usage of various waterproof materials to prevent water leakage. However, in reality, the effects of such waterproof measures are not being properly displayed, and further studies and evaluation are required. This journal invites authors to publish papers regarding development of successful waterproofing construction or materials for the protection of concrete structure roofing and below-grade walls. When it comes to promoting an active discussion on how to establish a systemized and internationally standard waterproofing method of concrete structures, we are hopeful that this Special Issue can provide a starting base for such an academic platform. The topics of interest include but are not limited to; Performance of waterproofing materials for roof and below-ground concrete structures; Anti-corrosive waterproofing materials for concrete water tanks; Root-penetration resistance materials for waterproofing of artificial ground; Required performance properties for waterproofing materials and execution methods; Evaluation methods for waterproofing materials; Repair materials for water-leakage cracks in concrete structures; Prevent technology of water leakage for concrete structures; Sealant technology; Other technologies related to waterproofing materials, execution methods, test methods, etc.
Keywords: waterproofing material; concrete structure; water leakage prevention; concrete durability.
