Waterproof polymer mortar construction method

Waterproof polymer mortar construction method 1. Waterproof polymer mortar can use pressure, surface construction, and well layered daub. Mortar shall be compacted and erased. 2. Ordinary should adopt multi-layer waterproof polymer mortar plastering construction, and should be in the top layer of mortar bond before daub after a layer of mortar. Appropriate to 18 mm - mortar total thickness 20mm。 3. The thickness of the polymer cement waterproof mortar, waterproof layer of metope, indoor, the appropriate thickness is 3 mm - 6毫米; The single layer thickness of underground waterproof layer, mortars appropriate for 6 mm - 8 mm, double thickness of 10 mm - 12mm。 4. Mortar combining the layers of the waterproof layer, each layer of appropriate continuous construction, when need to leave a construction joint, the ladder should be adopted if slope form, and shall not be less than 200 mm, from the Angle of Yin and Yang was on the lower pick if should be staggered at least 100 mm. The waterproof layer of Yin and Yang Angle should be made into circular! 5. Do mortar waterproof layer is level, should be set frame joints, frame joint spacing should not be greater than 6 m, seam appropriate for 20 mm wide, frame joint should be embedded fill seal materials, and should be consistent with existing national standards 'roofing construction technical specifications' GB 50345. 6. Mortar condenses after curing, surplus moisture curing, curing time should not less than 14 d. 7. Waterproof mortar condenses before hardening, may not be directly affected by water washing. Water storage structure should take mortar strength to meet the design requirements after water injection.
