济南防水层外露基本上有着价格便宜且施工方便快速的优点，但往往也常因现场判断的经验不足而失败，最主要的还是，任何防水材在紫外线与大自然的环境下，若直接外露则会加速老化，任由你是选择多好的防水材，济南防水认为仍然抵不过防水材会老化的事实。
Jinan has a waterproof layer exposed basically inexpensive and quick and easy construction of advantages, but also because often the scene of the lack of experience and judgment failed, the most important thing is that any waterproof material at ambient ultraviolet light and nature, if it is directly exposed will accelerate the aging, and let you choose how good waterproof material,waterproof material will still arrived, but the fact of aging Jinan waterproof think.
防水施作后加以覆盖(如：乳化沥青、橡化沥青、防水毯等等)，则会延长防水层的使用寿命，这也就是为什么一些老旧建筑物采用覆盖型的沥青防水，经过十几二十年都仍然不见渗露的原因了。不过，在防水层上面加上覆盖的保护，虽有着施工费用较为高昂的缺点，但是，以长期的经济效益来说，济南防水认为是值得的。
After applying a waterproof cover for them (eg: emulsified asphalt, rubber-based asphalt, waterproof blanket, etc.), will extend the life of the waterproof layer, which is why some of the old buildings using bitumen-covered, after more than a dozen Twenty years have still not seen a reason of leakage. However, top with waterproof layer covering the protection, though relatively high construction costs have shortcomings, however, long-term economic benefits, the Jinan waterproof think it is worthwhile.
