Description

When the roof area of the building is large, it is necessary to set deformation joints through the slab to ensure that the building will not crack when it expands and shrinks under the influence of temperature. However, the deformation joint is a great hidden danger in the roof waterproofing system, and it is extremely difficult to repair once the water leakage occurs. Conventional planting roof deformation joint waterproofing, generally set up retaining walls on both sides of the deformation joint, and then install a water stop on the top of the retaining wall. Since the planting roof itself needs to be covered with soil, the soil will carry moisture, and prolonged exposure to moisture will cause the waterstop to age, resulting in water leakage.
