防水补漏基层要求
Requirements for waterproof leakage repair base
与防水材料接着的界面必须不可有膨鼓、起沙、蜂巢、木头、纸屑、污泥、小石块、也不能做在松 动不牢固的表体上,原因是附着性不良,再加上太阳紫外线破坏,建筑物本身热胀冷缩,以及水蒸气压 力破坏,容易造成防水层老化、失败。
The interface next to the waterproof material must not be bulging, sanding, beehive, wood, paper scraps, sludge, small stones, nor can it be made on the loose body. The reason is that the poor adhesion, together with the sun ultraviolet damage, the thermal expansion and contraction of the building itself, and the water vapor pressure damage, are easy to cause the aging and failure of the waterproof layer.
