目前，市场上防水材料品种繁多，用途、性能和质量各异。正确选用防水材料，避免带来不必要的麻烦。
1、选用防水材料首选具有防水永久性的，这样就减少了返工时费时、费力、费钱的麻烦，防水材料对光、热臭氧等具有一定的承受能力。卷材表面应平整，不允许有孔洞、缺边和裂口、疙瘩，胎基应浸透，不应有未被浸透的条纹，端头无明显渗油，厚度均匀，立放端部应无明显变形现象，标识要齐全。
The preferred choice of waterproof material with waterproof permanent, thus reducing rework tsuming, 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、绿色环保防水材料：气味浓、毒性大的防水材料，对人身健康有着极大的影响，给社会和家庭带来极大的痛苦，防水材料具有良好抗水渗透和耐酸碱性能。用手弯曲，正常温度下，卷材有柔性，不产生裂纹，不应发脆发硬。
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、经济实惠防水材料：选用防水材料，总希望既能达到永久防水效果，又要较低的使用成本投入。建议选择一些大型知名的生产商的产品，虽然价格高一些，但是质量相对较好，避免或减少使用后的维护麻烦。
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 wwn manufacturers of products,although the price is higher, but the quality is relatively good, avoid or reduce maintenance problems after use.
4、施工简便防水材料：防水材料整体性好，既能保持自身的粘结性，又能与基层牢固粘结，同时在外力的作用上，防水材料有较高的剥离强度，形成稳定的不透水整体。
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.
