Due to the good compactness of high-strength concrete, its impermeability and frost resistance are better than those of ordinary concrete, so it has a longer service life; the sealing performance at the joints of existing precast concrete walls is not good, which is easy to cause water seepage, thus affecting the indoor environment and resulting in poor use effect.
