1、防水是個系統(tǒng)工程，是工程管理學和材料工程學緊密配合的工程，忽視任何一個環(huán)節(jié)都會造成防水失敗。因此要從源頭把好技術關，依據(jù)防水基本原則選好防水材料，選擇專業(yè)防水施工單位精心施工精心管理。
Waterproof is a systems engineering, engineering management science and materials engineering works closely with neglect any one link will cause water to fail. So off from the source to better technology, based on the basic principles of waterproof waterproof material selected, choose a professional waterproof construction unit meticulously careful construction management.
2、防水設計要根據(jù)地域環(huán)境，設計與施工環(huán)境相匹配的材料和方案。
Waterproof design to match according to the geographical environment, design and construction of environmental materials and programs.
3、防水要剛?cè)嵯酀浪畬右c基層變化特性相匹配，盡量避免剛性防水層作為單獨防水層。剛性防水材料作為獨立的防水層用于跨度大的防水基層，如屋面、地下、室頂板、側(cè)立墻等。剛性防水作為獨立防水層易受到剛性基層開裂影響而產(chǎn)生微小的裂縫導致滲漏。
Waterproof to hardness and softness, waterproof layer to match the characteristics of grass-roots change, try to avoid rigid waterproof layer as a separate waterproof layer. Rigid waterproof material waterproof layer is used as a separate waterproof span the grassroots level, such as roofing, underground, room ceiling, its side wall. Rigid waterproof waterproof layer as a separate rigid base vulnerable to cracking and produce tiny cracks lead to leakage.
4、柔性防水層應做在堅實的防水基礎上，避免防水層下面有積水層，防水層做在保溫層上面。防水層在施工過程中難免出現(xiàn)微小破損，水會經(jīng)破損處滲漏到保溫層，導致雨天小漏，天晴后大漏的現(xiàn)象。
Flexible waterproof layer should be done on the basis of a solid waterproof, avoid waterproof layer below the water layer, waterproof layer to do the insulation layer. Waterproof layer inevitable minor damage during the construction process, the water would leak through the breakage to the insulation layer, resulting in a small leak rain after sunny large leak phenomenon.
5、采用多層復合防水時，防水層之間要疊加相容。隔層施工，如在屋頂做三層SBS防水卷材防水層，做一道防水層，批一道水泥砂漿層;做一道聚氨酯防水涂料，再做一道自粘卷材。
When using multi-layer composite waterproof, between the waterproof layer to overlay compatibility. Barrier construction, as do the three SBS waterproofing membrane roof waterproofing layer,making a waterproof layer, grant a cement mortar layer; do a polyurethane waterproof coating, do a self-adhesive membrane.
