關(guan)于大(da)連防(fang)水施工(gong)你還有哪些想了(le)解的！

  經(jing)過(guo)市場(chang)的(de)(de)調查發現，全國的(de)(de)防(fang)(fang)(fang)水市場(chang)大多數(shu)都是(shi)相(xiang)同的(de)(de)原因，主(zhu)要是(shi)價格因素(su)作怪。在激烈的(de)(de)市場(chang)競爭(zheng)中(zhong)，很(hen)大一部(bu)分(fen)施工(gong)(gong)單(dan)位為了(le)降低工(gong)(gong)程(cheng)(cheng)成本都以犧牲防(fang)(fang)(fang)水工(gong)(gong)程(cheng)(cheng)的(de)(de)質量(liang)作為代價，不在乎防(fang)(fang)(fang)水工(gong)(gong)程(cheng)(cheng)質量(liang)壽(shou)命。防(fang)(fang)(fang)水工(gong)(gong)程(cheng)(cheng)質量(liang)的(de)(de)優劣(lie)、壽(shou)命的(de)(de)長短直(zhi)接取決于(yu)防(fang)(fang)(fang)水材(cai)料的(de)(de)質量(liang)，比如(ru)某地(di)最(zui)低氣溫零下(xia)18度，但是(shi)我(wo)們(men)卻選擇(ze)了(le)耐(nai)低溫零下(xia)10度或者-5度、0度的(de)(de)防(fang)(fang)(fang)水材(cai)料來做防(fang)(fang)(fang)水，經(jing)過(guo)熱脹冷(leng)縮防(fang)(fang)(fang)水層會逐(zhu)漸開裂而失去防(fang)(fang)(fang)水的(de)(de)工(gong)(gong)程(cheng)(cheng)。
