●Applicable waterproof membrane series: self-adhesive polymer modified asphalt polyester tire waterproof membrane, self-adhesive polymer modified asphalt waterproof membrane, self-adhesive EVA / HDPE polymer waterproof membrane
●Construction process flow:
Construction preparation → Base layer treatment → Brushing supporting base layer treatment agent → Construction of additional layers of detail nodes → Bouncing datum line → Large surface self-adhesive coiled material paving → Exhaust compaction → Lap edge compaction and sealing → Facade coil material collection Head fixing and sealing → inspection and acceptance → protective layer construction
●Construction preparation: including main materials, auxiliary materials, construction base, on-site conditions, technical solutions, etc.
●Base layer treatment: The base layer should meet the requirements of the specification, and should be flat, clean and dry; the yin and yang angles at the junction of the flat and vertical surfaces should be made into arcs.
●Brush the base layer treatment agent After the base layer treatment meets the requirements, the base layer surface is painted (or sprayed) to match the base layer treatment agent. The coating (or spraying) of the base treatment agent should be even and consistent, and should not be exposed. The surface should be dried before the roll material is applied.
●Construction of additional layers of nodes: Add additional layers to the nodes according to relevant specifications or design requirements. The additional layer of general parts is full of stickiness, and the parts with stress concentration should be laid empty according to the requirements of relevant regulations.
●Laying large waterproof membrane:
●Horizontal spreading: firstly pop up a base line on the base layer, then spread from low to high, unwind the roll while peeling off the release paper, spread along the base line, and the width of the roll is ≥100mm. Immediately after paving, the roll should be compacted with a pressure roller.
●Vertical surface paving: The vertical surface is paved from low to high, and the isolation film is uncovered while unfolding. The width of the overlapping edge is the same as above; after paving, use the pressure roller to compact it.
●Side wall waterproof layer construction: first position the coiled material on the base layer of the underground continuous wall according to the elastic reference line, the self-adhesive isolation membrane of the coiled material faces the side wall structure, and use special concrete steel nails to fix the coiled material in the underground continuous On the base layer of the wall; peel off the isolation film on the edge of the joint and make a long-side lap.
