How to use elastomer modified bitumen waterproofing membrane

How to use elastomer-modified bitumen waterproofing membrane SBS waterproofing membrane uses styrene-butadiene-styrene (SBS) thermoplastic elastomer as modifier asphalt as the impregnating and coating material, and the upper surface is covered with polyethylene Film, fine sand, mineral sheet (granule) material or aluminum foil, copper foil and other isolation materials can be rolled into a sheet-shaped waterproofing membrane. According to the physical index, it is divided into two categories: I (-18℃) and II (-25℃), which respectively refer to the physical indexes of the low temperature resistance of the coil. Therefore, the II type should be more resistant to low temperature (low temperature flexibility is good, reaching -25 ℃ does not crack), the price is higher, not the quality of the material is inferior to the I type.





If there is a crack at the root of the deformed joint wall and water is leaking, the coil at the crack should be cut open. After the base layer is expanded, the waterproof sealing paste is inserted. After the coil strip is empty, the original waterproof layer is repaired and the original waterproof layer is strengthened. When the coiled material on the top surface of the deformation joint wall is cracked or damaged, the concrete cover plate should be removed and repaired again. 　Water falls and leaks. Phenomenon. 　Water leaks around the water fall, and some water fall surface is higher than the waterproof layer and water accumulates, or because the water fall is small, it is blocked and overflows.

Elastomer modified bitumen waterproofing membrane How to use waterproofing membrane is mainly used for building walls, roofs, tunnels, highways, etc., a flexible building material that can be rolled into a roll to resist external rain and groundwater leakage The product, as a leak-free connection between the engineering foundation and the building, is a waterproof barrier for the entire project, and plays a vital role in the entire project. The main products are bituminous waterproofing membranes and polymer waterproofing membranes. This article describes in detail the construction methods and precautions of waterproofing membranes.





Unfold the self-adhesive waterproof membrane and align it with the reference line and try to lay it first to see if the desired effect can be achieved. At this time, we need to pay attention to laying the membrane of the membrane facing down. 　When paving, start with the plane first, and then pave the facade. Open the roll and lift the release paper from one end. This action requires two people to cooperate. One person pulls the removed release paper and pulls it back evenly, slowly pulls out the entire release paper, and the other removes the release. The part of the paper is pasted on the base layer.


Since there are no double bonds in the main chain of the EPDM molecular structure, when it is exposed to ozone, ultraviolet rays, and damp heat, the main bond is not easy to break, so it has excellent weather resistance and aging resistance. Moreover, the tensile strength is high, the elongation is large, the adaptability to the expansion or cracking of the base layer is strong, the value, the weight is light, and the temperature range is wide (long-term use within the range of -40～+80℃). It is an efficient waterproof material . It can also be used for cold construction, easy to operate, reduce environmental pollution, and improve workers' working conditions. Waterproof membranes have gradually transferred from unenvironmental engineering membranes to environmentally friendly household membrane manufacturers. This new business opportunity will make it lasting for a long time in the future. Polymer environmentally friendly waterproof coatings, with its environmentally friendly, durable, sturdy, easy to use and other characteristics, quickly enter ordinary homes, so it has created a huge market for waterproofing membranes, and the market prospects are inexhaustible. 　So, on the whole, whether it is engineering construction or the civilian market with a family as a unit, the prospects for waterproofing membranes are very broad.





2gt, the placement of coils. Before the roll material is laid, the roll material needs to be unrolled from the tightly rolled state on the qualified base layer to allow it to shrink freely from the stretched state. The stress generated during the production of the roll material during the crimping process can avoid the adverse consequences caused by the subsequent shrinkage of the roll material . 　3gt, the membrane waterproof layer is fully glued. 　I Lay a horizontal waterproof layer. 　Unfold and position the coil: Fold the coil back in half so that half of the bottom surface of the coil is exposed. The folded coil should be smooth and free of wrinkles.


Coils are divided into synthetic polymer coils, polymer modified asphalt coils, and asphalt coils. Different coils have different requirements for construction temperature. 　Synthetic polymer coiled material has high resistance and good low temperature performance. There is no problem in uncoiling. Different construction methods have different requirements for temperature conditions. The cold bonding method mainly considers the influence of high and low temperature on the binder. The binder of polymer coils is divided into solvent volatilization, two-component reaction curing type and hot melt type. The first two are volatilized or reaction speed at low temperature. Too slow, so it is required to apply at a temperature above 5°C, while the hot melt adhesive can be applied at -10°C. Please pay attention to Shandong Yuexu building materials manufacturers. 　How to operate the standardized SBS waterproof coiled roof construction technology? Come and study together today. 　Construction tools: blowtorch, pulley, brush, pressure roller, scissors, tape measure, broom, etc. 　Construction process: Material preparation technology prepares the base layer treatment, coating primer, and detailed treatment coils, test paving, coil protection layer quality inspection, and finished product protection. 　 Primary treatment. 　The leveling layer should be smoothed with cement mortar, the base layer and the protruding roof structure (such as parapets, skylights, deformation joints, chimneys, pipes, flagpoles, etc.) connecting the Yin and Yang angles, the base layer and cornices, gutters, drainage outlets. If there are other related requirements, the corners connected by the edges of the ridges and ridges should be wiped into a smooth arc shape, and the radius is generally 50 mm.
