Protection-free Polymer Composite Waterproof Membrane

Product Description

Protection-free Polymer Composite Waterproof Membrane

1.1 Material introduction
1. Product introduction
It is a kind of strong polymer film as the main reinforcement material. The coating layer is a reactive self-adhesive with additives such as active agent and water immersion agent. The upper surface is covered with non-woven fabric for reinforcement, and the lower surface is covered with silicone oil. Composite waterproofing membrane made of mucosa.
The surface is covered with non-woven fabric to protect the waterproof layer. After the coil is laid, it does not need to be coated with a cement mortar protective layer, and other activities such as binding steel bars can be directly tied, which not only shortens the construction period, but also saves a lot of costs.

Water Resistant Material
3. Product features
(1) Good rainproof performance, high mechanical strength, super adhesion, forming a firm and irreversible sealing waterproof layer, preventing water channeling, integrating high polymer strength, large extension, aging resistance and creep resistance of reactive sealant Cracking and sealing are combined to form a multiple waterproof system.
(2) The construction is simpler and safer, and the construction progress is particularly fast; the cross construction time is relatively short. The construction schedule can be greatly shortened, which is conducive to rushing the construction period and is convenient for maintenance management.
(3) Low requirements for grassroots, convenient construction, low cost and cost saving.
(4) The construction conditions are low, and the construction can be carried out in rainy weather or wet base surface, and the application range is wide.

4. Implementation standards

1.2 Process introduction
1. Process flow
Dry-laying method: base surface cleaning and acceptance → brushing of base treatment agent → waterproof layer laying → detailed enhancement treatment → quality acceptance → subsequent construction
Wet paving method: base surface cleaning and acceptance → base surface wetting → bonding material mixing → waterproof layer laying → detailed enhancement treatment → quality acceptance → subsequent construction

2. Process introduction
Dry shop method:
(1) First, lay permanent protective walls, pits (such as elevator shafts, independent foundations) and other special waterproof layers, and then carry out large-scale construction. When laying the coil, first pre-lay the coil on the base surface according to the reference line, the non-woven fabric of the coil is facing up, and the self-adhesive layer is facing down to bond with the cushion. The lap joints of the short sides of two adjacent coils should be staggered by 500mm.
(2) When the coils are vertically overlapped, they are overlapped by pressing the long side against the short side (the long side is on the top and the short side is on the bottom).
(3) When laying coils, pay attention to the width of overlap and swing. At the same time, the coils should be natural and smooth without distortion. It should be noted that the tightness of adjacent coils on the flat surface, yin and yang angles, etc. should be appropriate and consistent.
(4) The lap width of the long side and the short side of the coil is not less than 80mm.
(5) When carrying out the lap joint operation of the coil, remove the isolation film covering the lap side to ensure that the lap joint is clean and dry. Use a pressure roller to compact the lap side of the coil and discharge the air from the lap side to tightly press Really sticky. Repeat the above operations until the laying of flat coils is completed.
(6) In the case of rain, snow, and windy weather during the construction process, the protection of the rolled materials should be done well.

Wet paving method:
(1) If the base layer is dry, the base layer needs to be fully sprinkled with water to reach a saturated state, and the construction can be carried out without clear water.
(2) Preparation of cement slurry: according to the weight ratio of cement: water = 2:1, stir it evenly in the batching bucket with an electric mixer. First, pour water into the bucket, then pour the cement, and soak the cement in the bucket for 10 -15 minutes later, pour out the floating water on the top, and then start mixing. The preparation of cement slurry must be uniform without precipitation and lumps; add more when the weather is dry and hot, and less when the weather is cool and humid.
(3) During construction, if the base layer is too dry, water should be sprayed on the base layer to increase the humidity to ensure the moisture needed for curing the bonding layer.
(4) The adhesive layer shall be covered with slurry with a scraper, and shall not be exposed. It is required to overflow and not lose. The cement slurry shall not be applied to the overlap of the two coils to prevent contamination of the joints and affect the joint bonding quality.
(5) Overlap width: The overlap width should be 80mm. Coil lap construction must be carried out carefully, and the lap joint must be firmly adhered and compacted.
