Working principle of water expansion rubber strip

In all kinds of underground construction engineering, hydraulic engineering, tunnel engineering, municipal water supply and drainage engineering, water pool, swimming pool, building a large number of applications to pull the bolt, and various wall pipe water pipes in hardened concrete, it is easy to form a small gap, but also on the formation of the leakage passage in the present construction is the plate in the middle 2mm method of thick annular sealing ring welding, to extend the low permeability seepage water, but also often have leakage phenomenon。 The building water is generally not waterproof measures, resulting in a layer of water, the lower the dripping phenomenon。

Such as the use of water swellable rubber, when water seeping into the end, can rely on their own water swelling pressure, compaction of concrete structures, and the pipeline of the bolt gap, blocking the leakage passage, to achieve permanent waterproof effect.
