Answer:
(1) The most common areas where water leaks occur in the flowerbed are:
(1) Corners and corners where the reinforcement or batch grouting construction is being carried out.
(2) Around the submerged head.
(ii) The waterproofing of the platform below is often overlooked and is also the most likely to fail:
(1) First, prime the surface and then apply a waterproof coating.
(2) Waterproofing of the platform for pipe relocation.
(3) The construction seams, which are divided into several stages, were not treated beforehand; they were directly applied as waterproofing on the platform.
(4) The flowerbed design is too elaborate; first, use a salad oil barrel, plastic film, trash, and so on; then, lay a layer of inferior concrete as the base, and then build a waterproof flowerbed.
(5) If the waste and impurities on the flowerbed are not cleaned off before waterproofing, the flowerbed will be considered waterproof.
(6) Improper selection of waterproof materials (such as waterproof glue that easily crumbles when immersed in water).
