Waterproofing membrane is mainly used in building walls, roofs, and tunnels, highways, etc., to resist external rainwater, groundwater seepage of a flexible building materials products can be curled into a volume, as the foundation of the project and the leak-free connection between the building, is the first barrier to the entire project waterproofing, plays a vital role in the entire project. Products are mainly asphalt waterproofing roll-roofing and polymer waterproofing roll-roofing. The following waterproofing materials manufacturer details the construction methods and precautions for waterproofing roll-roofing materials.
1, waterproofing material manufacturers: the base surface requirements:
Base cleanup, moisture content of not more than 9%, flat and dense, the nodes are neat and complete, in line with the requirements.
2, waterproofing materials manufacturers: the first waterproof layer:
(1), laying a flexible waterproofing layer, choose paint or coil can be. Its construction conditions require the moisture content of the base surface is not greater than 9%, so it is suitable for hot weather and even after 5 days of clear summer construction. After the completion of the work, should do water storage experiments.
(2), such as doing paint waterproofing, to "a cloth two coatings" as an example: clean up the grass-roots level, full brush a coating, dry film, lay a layer of glass fiber fabric tire reinforcement material, and in the flattened surface full brush a layer of paint fixed, dry after the next coating construction. The total thickness of the waterproof coating film should be more than 3 mm.
(3), such as waterproofing coil construction, clean up the grass-roots level, the reverse side of the coil and the grass-roots level brush bonding adhesive, according to the play good reference line by far and near the paste, roller pressure, and finally do the seam header check processing.
3, waterproofing material manufacturers: the second waterproof layer:
Laying rigid waterproofing layer, should be in the first flexible waterproofing layer after the completion of about two days of construction, mainly with advanced fatty acid class mortar waterproofing agent, cement, sand, fine stone aggregate, fiber as the basic material, waterproof layer thickness should be 20-30 mm.
(1), according to the specification requirements for the installation of compartmentalized wood strips, compartmentalized set for 4000 mm × 4000 mm. Then sprinkle water to make the base surface wet, but there shall be no standing water.
(2), according to the order from far to near, first high and then low, the prepared mortar or fine stone concrete will be constructed one by one, the same compartment is completed at one time, smoothed and compacted.
(3)、After the initial setting, take out the grading wooden strips, calendering and trimming the grading joints.
(4)、Adopt flexible sealing material to inlay the compartment joints and deal with the surface closure. Pay attention to watering maintenance after the construction is completed. (5), if there is roofing soil, should be covered with planting soil in the shortest possible time
