濟(jì)南防水層外露基本上有著價格便宜且施工方便快速的優(yōu)點，但往往也常因現(xiàn)場判斷的經(jīng)驗不足而失敗，最主要的還是，任何防水材在紫外線與大自然的環(huán)境下，若直接外露則會加速老化，任由你是選擇多好的防水材，濟(jì)南防水認(rèn)為仍然抵不過防水材會老化的事實。
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.
防水施作后加以覆蓋(如：乳化瀝青、橡化瀝青、防水毯等等)，則會延長防水層的使用壽命，這也就是為什么一些老舊建筑物采用覆蓋型的瀝青防水，經(jīng)過十幾二十年都仍然不見滲露的原因了。不過，在防水層上面加上覆蓋的保護(hù)，雖有著施工費(fèi)用較為高昂的缺點，但是，以長期的經(jīng)濟(jì)效益來說，濟(jì)南防水認(rèn)為是值得的。
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.
