If there are any mortar lumps, they should be eradicated. Defects in the concrete base surface have been repaired. 2. Clean the debris on the base surface to ensure that the base surface is clean and free of dust, laitance and oil. 3. The base layer must be fully moist, but there should be no accumulation of water. (2) Ingredients The waterproof coating is prepared according to the proportions: Spray paint XYPEX: Water 5:3 volume ratio Painting material XYPEX: Water 5:2 (volume ratio) The water used for the ingredients should be salt-free and without harmful ingredients. Pour the weighed materials into the mixing bucket according to the proportion, start the mixer, and slowly add the mixed powder while stirring, stir for 3-5 minutes, stir thoroughly and evenly without any lumps, and mix well before coagulation (no more than 20 minutes) )run out. The XYPEX coating solution should be prepared in 2 passes at 1.0kg/m2. The ingredients must be completed in one go, and adding water twice is strictly prohibited. (3) Coating spraying and scraping (1) XYPEX adopts spraying method for large-area operations, and scraping method for partial construction. (2) The order of spraying and scraping: first apply node parts, then scrape the large area. (3) Spraying must be done vertically and horizontally, and the spraying directions across the overlap should be staggered. (4) When applying the second layer, wait until the first layer has set and it is dry to the touch. If the first layer is dry, spray some mist first and then apply the second layer. (5) In hot weather, open-air construction must be carried out in the morning and evening to prevent XYPEX from being soaked due to excessive drying; it must not be covered with plastic sheeting. (6) The coating at corners and nodes should be sprayed multiple times without flowing or accumulation.

The root of the pipe needs to be sealed with sealing material first, and then painted. (4) Inspection (1) Check whether the XYPEX coating is applied evenly and whether there are any missing parts, otherwise it needs to be re-coated. (2) After the XYPEX coating construction is completed, it is necessary to check whether there is peeling in the coating. If so, 6 remove the exposed areas first, then treat the base surface, and then paint with XYPEX paint. (3) For the rework of XYPEX coating, the base surface of the reworked part needs to be wet and polished. If dryness is found, spray water to moisten it before proceeding with coating construction. (5) Maintenance (1) Tap water must be used. No matter whether it is painted for the first or second time, the maintenance must be carried out immediately after the material is dry. Use spray water or small water without impact for maintenance. Be sure to avoid water pipes. Rinse the coating directly.

(5) Test according to corresponding technical indicators. B: SBS waterproof material (1) Operating conditions (1) The surface of the leveling layer should be solid and flat, and the drainage slope meets the design requirements. When cement mortar is used to level the layer, it should be smoothed and calendered, and fully cured. There should be no looseness, sanding, or looseness. Peeling phenomenon. (2) The connection between the base layer and the protruding roof structure, as well as the corners of the base layer, should be evenly formed into arcs (R corners), and the radius of the arcs should not be less than 50mm. (3) In areas north of 40°C and where the indoor air temperature is greater than 75°C or where it is difficult to dry the roof insulation layer and leveling layer, a steam exhaust roof should be used. The design of the steam exhaust roof should comply with GB50207-94 standard section 4.3. 14 items. (4) Before laying the waterproof layer, the base layer must be clean, dry, and a simple test method 7 is to lay one square meter of rolled material flatly on the leveling layer, let it sit for 3 to 4 hours, then open it for inspection, and check that the part covered by the leveling layer A waterproof house can be laid without watermarks on the membrane. (5) The construction residue, mortar, debris, etc. on the base surface must be cleaned up. Three construction methods 1. Strengthen the details, and separate the slab joints of the prefabricated reinforced concrete slabs, reserved roof deformation joints, settlement joints and leveling layers. The grid joints should be filled with glue first, and an additional layer should be made on top of them and at other preset R corners of the roof. 2. Before paving the membrane, apply traditional asphalt cold base oil or a base treatment agent compatible with the material properties on the base layer. Apply evenly without revealing the bottom, and the drying time is 6 to 10 hours. 3. The rolling materials should be laid upward from the lowest elevation of the roof. When the roof slope is less than 3, the rolling materials should be laid parallel to the ridge. When the roof slope is greater than 3, the rolling materials can be laid parallel or perpendicular to the ridge. The rolling materials When paving, elastic lines should be positioned on the base layer, and the overlap width should not be less than 100mm on both long and short sides. 4. When using the hot melt method to lay the membrane, it should comply with the provisions of Article 4.6.5 of GB50207-94. 5. The second course of membrane paving should be staggered on the surface of the first course of membrane (the base surface is no longer used). 6. After the construction of the waterproof membrane is completed, the waterproof layer must be protected and inspected to prevent artificial The waterproof layer is damaged due to damage. If any damage is found, it will be repaired and the protective layer can be constructed only after the treatment is completed. 7. After the second waterproof layer of the base plate is completed, the protective layer of asphalt linoleum is point-paved. Four detailed structure waterproofing construction (1) Pipes (boxes) passing through the main structure and waterproof layer (2) Wall-penetrating pipe boxes should be pre-buried before pouring concrete. (3) The distance between the penetrating wall and the interior corners and concave and convex parts should be greater than 250mm. 8 (4) When the structural deformation or the pipe expansion and contraction is large, the wall-penetrating pipe can adopt a fixed waterproofing method in which the main pipe is directly buried in the concrete. A water-stop ring or a rubber strip that expands when exposed to water should be installed in the middle of the wall-penetrating pipe, and the water-swelling rubber strip should be installed in advance. Leave a groove and fill it tightly with caulking material. (5) The distance between tubes should be greater than 300mm. (6) When there are many pipelines passing through the wall, they should be relatively concentrated and the wall-through box method should be used. The sealing steel plate of the wall box should be welded tightly to the reserved angle steel on the wall, and sealing material or fine stone concrete should be injected from the reserved pouring hole on the steel plate. (7) Where wall-through pipes protrude from the exterior wall, effective measures should be taken to prevent damage to the pipes during backfilling.

5. Embedded parts and reserved holes (troughs) (1) The embedded parts on the hooks should be pre-buried (2) The thickness of the concrete buried at the designed end or at the bottom of the reserved hole (trough) shall not be less than 250mm. When the thickness is less than 250mm , local thickening or a coiled material should be added in the hole (slot) to meet the specification requirements. (3) The waterproof layer inside the reserved hole (slot) must be continuous with the structural waterproof layer outside the hole (slot). (5) Acceptance The acceptance of this project shall be in accordance with the requirements of Guangdong Province GB50208-2002 "Quality Acceptance Standard for Basement Waterproofing Projects" and the "Technical Regulations for Building Waterproofing Engineering" DBJ15-19-97. 1. The rolling material paving method and overlapping sequence should comply with regulations. The overlapping width should be correct, the joints should be tight, and wrinkles and warping should not be allowed. 2. Inspection of whether there is leakage or accumulation of water on the roof can be carried out after rain or after continuous water spraying for 2 hours. Roofs that are likely to be inspected for water storage should be stored for 24 hours. If there is no leakage, it is qualified. 3. After the waterproofing project is completed and accepted, the user should assign a dedicated person to be responsible for roof management. It is strictly prohibited to drill holes in the waterproof layer and impact with heavy objects; it is not allowed to pile up debris and add structures on the roof. 4. Strictly prevent waterproofing, gutters, and eaves from being blocked, and keep the roof drainage system smooth. Chapter Six Protection Measures for Finished Products 1. Construction workers should wear soft-soled rubber shoes when entering the waterproof construction zone. 2. After the construction of the waterproof layer is completed, a protective layer of fine stone concrete and mortar should be made in time. No hard objects are allowed to be dragged on the waterproof layer, and heavy or hard objects are not allowed to be stacked. 3. When making a protective layer, vehicles such as trolleys transporting materials must use inflatable rubber wheels. 4. When the trolley overturns mortar or fine stone concrete, the lower part of the trolley must be padded with thick wooden boards to prevent the lower end of the trolley from directly contacting the waterproof layer to prevent puncture of the waterproof layer. 5. After the waterproof layer is accepted, the mortar protective layer should be laid immediately. Only after the mortar reaches a certain strength can workers proceed with the next construction process. Transporting and moving heavy equipment on it should be avoided. 6. Before making the protective layer, try to Avoid welding steel bars on the waterproof layer. When welding is necessary, use plywood to block the welding part to prevent welding sparks from burning the waterproof layer. Chapter 7 Project Management Organizational Structure 1.
