[0001] The utility model relates to the technical field of waterstop strips, in particular to an externally attached anti-cracking rubber waterstop strip. Background Art

[0002] Rubber waterstop is made of natural rubber and various synthetic rubber as the main raw materials, mixed with various additives and fillers, and formed by plasticization, mixing and pressing. The external rubber waterstop is also called back-sticking waterstop or external waterstop. It is a waterstop structure installed on the outside of the concrete deformation joints and settlement joints of underground structures. The external rubber waterstop utilizes the high elasticity of rubber to produce elastic deformation under various loads, thereby playing a solid seal, effectively preventing leakage and seepage of the building structure and playing a shock-absorbing and buffering role.

[0003] After searching, it was found that the external rubber waterstop has the problem of poor protective effect when in use. For example, the external rubber waterstop ages quickly during use. Once the rubber ages, it is prone to cracking, thereby reducing the waterproof effect. In addition, the drainage efficiency of the external rubber waterstop is low.
