目前，市場(chǎng)上防水材料品種繁多，用途、性能和質(zhì)量各異。正確選用防水材料，避免帶來(lái)不必要的麻煩。
1、選用防水材料首選具有防水永久性的，這樣就減少了返工時(shí)費(fèi)時(shí)、費(fèi)力、費(fèi)錢(qián)的麻煩，防水材料對(duì)光、熱臭氧等具有一定的承受能力。卷材表面應(yīng)平整，不允許有孔洞、缺邊和裂口、疙瘩，胎基應(yīng)浸透，不應(yīng)有未被浸透的條紋，端頭無(wú)明顯滲油，厚度均勻，立放端部應(yīng)無(wú)明顯變形現(xiàn)象，標(biāo)識(shí)要齊全。
The preferred choice of waterproof material with waterproof permanent, thus reducing rework time-consuming, laborious, cumbersome and costly, waterproof material to light, heat and ozone, have a certain tolerance. Membrane surface should be smooth, not allowed to have holes, missing edges and cracks, knots, padding should be soaked, there should not soaked streaks, end no oil leakage,uniform thickness, stand up ends should be no significant deformation phenomenon, identifies complete.
2、綠色環(huán)保防水材料：氣味濃、毒性大的防水材料，對(duì)人身健康有著極大的影響，給社會(huì)和家庭帶來(lái)極大的痛苦，防水材料具有良好抗水滲透和耐酸堿性能。用手彎曲，正常溫度下，卷材有柔性，不產(chǎn)生裂紋，不應(yīng)發(fā)脆發(fā)硬。
Green waterproof material: Odor thick, toxic waterproof materials, has a great impact on human health, to social and family brings great pain, waterproof material has good resistance to water penetration and acid and alkali resistance. Hand bend, the normal temperature, flexible membrane, no cracks, not brittle and stiff.
3、經(jīng)濟(jì)實(shí)惠防水材料：選用防水材料，總希望既能達(dá)到永久防水效果，又要較低的使用成本投入。建議選擇一些大型知名的生產(chǎn)商的產(chǎn)品，雖然價(jià)格高一些，但是質(zhì)量相對(duì)較好，避免或減少使用后的維護(hù)麻煩。
Use waterproof material, hoping both to achieve permanent waterproofing effect, but also the use of lower cost inputs. Recommended to choose a number of large well-known manufacturers of products,although the price is higher, but the quality is relatively good, avoid or reduce maintenance problems after use.
4、施工簡(jiǎn)便防水材料：防水材料整體性好，既能保持自身的粘結(jié)性，又能與基層牢固粘結(jié)，同時(shí)在外力的作用上，防水材料有較高的剝離強(qiáng)度，形成穩(wěn)定的不透水整體。
Waterproof material integrity, and can maintain its cohesiveness, but also firmly bonded with the grass roots, while the role of external forces, waterproof material with high peel strength,impervious to form a stable overall.
