构造防水是采取合适的构造形式，阻断水的通路，以达到防水的目的，如止水带和空腔构造等。 主要应用领域包括房屋建筑的屋面、地下、外墙和室内；城市道路桥梁和地下空间等市政工程；高速公路和高速铁路的桥梁、隧道；地下铁道等交通工程；引水渠、水库、坝体、水利发电站及水处理等水利工程，等等。随着社会的进步和建筑技术的发展，建筑防水材料的应用还会向更多领域延伸。
Structural waterproofing is to take appropriate structural form to block the water access to achieve waterproofing purposes, such as water stop zone and cavity structure. The main application fields include roofing, underground, exterior wall and interior of building; municipal engineering such as urban road, bridge and underground space; bridges and tunnels of Expressway and high-speed railway; traffic engineering such as underground railway; water conservancy projects such as diversion canals, reservoirs, dams, hydroelectric power stations and water treatment, etc. With the progress of society and the development of construction technology, the application of building waterproof materials will extend to more fields
