Reinforced rubber waterstop, also named hydrophilic rubber waterstop, swelling rubber waterstop, can expand when it is in touch with water which mainly depend on the expansible strip. Hydrophilic rubber waterstop is made from natural rubber or synthetic rubber, adding various additives and fillers, through the process of plasticizing, mixing, pressing, forming. Buried rubber waterstop, back stick rubber waterstop, steel edge rubber waterstop with waterproof line can be made into reinforced rubber waterstop. It uses unequal thickness structure, can be divided into high-strength area, the waterproof area and the installation area, allowing for uniform and reasonable stress for all portions. Telescopic holes' outer wall is plane; there are mounting holes in installation area which can make waterstop convenient to fix with the nearest steel bar, difficult to move.
