济南防水公司http://www.tianyujian.com/介绍由于技术方面的原因，施工过程中砂浆或混凝土的拌和水量总是超过水泥水化所需要的水量，这部分多余的水分在砂浆或混凝土硬化过程中逐渐蒸发，这样便在硬化后的砂浆或混凝土中留下孔隙和毛细管道；另一方面砂浆和混凝土在硬化过程中， 常会因收缩应力而使屋面出现一些收缩裂缝。
Jinan waterproofing company introduced due to technical reasons, the amount of water mixing mortar or concrete construction process is always more than the amount of water needed for cement hydration, this part of the gradual
evaporation of excess water in the mortar or concrete hardening process, thus after hardening mortar or concrete pores and capillary channels left; on the other hand mortar and concrete in the hardening process, often leaving the roof
due to shrinkage stress some shrinkage cracks.
济南防水公司谈到砂浆或混凝土防水层在屋面上的面积较大，在受到昼夜溫差的影响时，热胀冷缩现象会导致刚性防水层出现一些无规则的开裂，这些裂缝同样也是造成屋面渗漏的原因。
Jinan waterproofing company comes to a larger area of mortar or concrete waterproofing layer on the roof, when affected by DIF, the expansion and contraction phenomenon will lead to some rigid waterproof layer cracking without rules,these cracks is also caused by infiltration of roof leakage causes.
济南防水公司http://www.tianyujian.com/分析在屋面防水层施工时，如果施工方法不当，出现如振捣不均匀、混凝土养护不到位等施工质量方面的问题，同样会影响到屋面的防水性能而出现渗漏。
Jinan waterproofing company analysis at the roof waterproof layer construction, if improper construction methods, such as vibrators appear uneven, the problem of construction aspects of quality of concrete curing is not in place, it will also affect the waterproofing and roof leakage.
