在卷材防水层中粘结不实的部位，窝有水分和气体，当其受到太阳照射或人工热源影响后，体积膨胀，造成鼓泡。 如果仅有一层不明显的白色小雾，说明保温层基本干燥，可以准备进行防水层的施工。测试完毕应注意将圆孔补平。采取这种测试方法，可以使施工人员比较准确地掌握保温层的干燥程度，以便及时安排防水层的施上。测试的时间宜选样在下午2—3点钟，此时保温定温度高，相对温差人，测试的结果明显、准确，对大面积屋面保温层应多测试几点，全面综合其检测数据，以提高其测试的准确性。
1、直径100mm以下的中、小鼓泡可用抽气灌胶法治理，并压上几块砖，几天后再将砖移去即成。
100mm diameter or less, and small bubbling available plastic irrigation pumping method of governance, and pressed a few bricks, a few days before the bricks removed Serve.
2、直径100～300mm的鼓泡可先铲除鼓泡处的保护层，再用刀将鼓泡按斜十字形割开，放出鼓泡内气体，擦干水分，清除旧胶结料，用喷灯把卷材内部吹干。随后按顺序把旧卷材分片重新粘贴好，再新贴一块方形卷材（其边长比开刀范围100mm），压入卷材下，最后粘贴覆盖好卷材，四边搭接好，并重做保护层。上述分片铺贴顺序是按屋面流水方向先下再左右后上。
Bubbling 100 ~ 300mm diameter may be bubbling at the eradication of the protective layer, and then a knife bubbling by oblique cross cut, release the bubbling gas, dry water, remove the old binder with a blowtorch to roll interior dry. Then in order to re-paste the old membrane fragments good, and then posted a new square coil (which side is larger than the surgery range 100mm), under the pressure of the membrane, and finally paste membrane covering the good, good lap four sides, both as a protective layer. Paving the above sequence is fragmented by roofing direction before you get on the water and then left.
3、直径更大的鼓泡用割补法治理。先用刀把鼓泡卷材割除，按上一做法进行基层清理，再用喷灯烘烤旧卷材槎口，并分层剥开，除去旧胶结料后，依次粘贴好旧卷材，上铺一层新卷材（四周与旧卷材搭接不小于100mm），然后贴上旧卷材。再依次粘贴旧卷材，上面覆盖第二层新卷材，最后粘贴卷材，周边压实刮平，重做保护层。
Larger diameter bubbling with cut and fill method of governance. A knife to cut off the first bubble membrane, a practice carried out by the primary clean-up, and then blowtorch baking sheet Croucher old port and layered peel, remove the old binder, and then click Paste good old roll, capped a the new membrane layers (four weeks old sheet lap of not less than 100mm), and then paste the old membrane. Then followed paste the old membrane, covering the top of the second layer of the new membrane, and finally paste membrane surrounding compacted Calibrating, redo protective layer.
