Elastomer bitumen waterproofing membrane manufacturers mostly use prefabricated panels for roofs in rural areas. Usually, the leaking part is the contact between the panels. Therefore, it is a simple and cost-effective repair method for leaks in the roof of rural bungalows. It is to spread a layer of asphalt on the roof to stick the joints, but the waterproof effect of this method is not lasting. The more durable method is to put a layer of waterproof layer on the left side of the roof or apply latex. SBS modified bitumen waterproofing membrane uses thermoplastic elastomer as modifier, modified petroleum bitumen as impregnating coating material.
The following takes petroleum asphalt paper tire felt as an example to introduce quality identification. How to identify low-quality waterproof membranes. Outer packaging: printed with the factory name, trademark, production license number, XK23-016, standard code, product label and grade, and date of manufacture. Linoleum roll weight: No. 350 powder felt weight, sheet felt weight ge, 200 powder felt weight ge, sheet felt weight ge, 500 powder felt weight ge, less than this weight is unqualified. Visual inspection.

Most of the waterproofing membranes used by the manufacturers of elastomeric asphalt waterproofing membranes for roof leaks are baked with an open flame, which not only has a high risk factor, but also leaks repeatedly...So are there any waterproofing membranes that do not require open flame construction? Today, the editor will introduce a non-fire-baked waterproof membrane, tear off the protective film, and automatically stick it under the sun. Construction method: Clean the base surface, keep it dry, peel and paste, the more the external heat will stick, the stronger it will be. There is a kind of waterproof membrane called self-adhesive waterproof membrane, which is similar to ordinary waterproof membrane with a layer of glue. After tearing off the protective film on the surface, the waterproof membrane can be glued to the waterproof base layer after treatment.
base surface cleaning, patching and brushing the matching base treatment agent node position paste positioning, elastic datum line paving self-adhesive rubber waterproof membrane rolling, exhaust head treatment and lap organization acceptance protection layer construction. Wet paving method. Clean the wet base layer (if the base layer is wet, this process is not necessary), locate, stir and spread the cement slurry to pave the coiled material to lift the slurry, vent, let the overlap edge seal the coiled material to receive the head, seal inspection and accept. The key points of construction technology.
Grassroots treatment. The surface of the base layer should be fully dry, and there should be no unevenness, looseness, bulging, peeling, cracks, pitting, etc., check the flatness of the base layer surface with a 2M ruler, and the deviation shall not exceed 5mm. The yin and yang angles at the junction of the base layer and the protruding roof structure (such as parapet, standing wall, etc.) should be made into an arc with a radius. The drip line at the top of the parapet wall and the cornice should meet the requirements. The water drop should be suitable for laying the coiled material and the surrounding drainage should be good. Before laying the coiled material waterproof layer, dust, grease and other sundries should be placed on the base layer, and the surface of the base layer must be clean. The bonding performance is excellent, which can ensure the continuity and tightness of the lap joint of the coil to a large extent. High temperature resistance, low temperature resistance, anti-aging, long service life. Main control project acceptance specification. The waterproof structure of self-adhesive waterproofing membrane layer in gutters, gutters, cornices, water downs, flooding, deformation joints and extension layers of pipes must meet the design requirements. Inspection method: observe inspection and check the acceptance records of concealed works. The self-adhesive coil shall not have leakage or water accumulation.

FSA self-adhesive modified bitumen waterproofing membrane: model thickness: 3mm, price: 51 yuan/m2.
One person slowly lifts the peeling barrier paper and rolls it onto the paper core tube and moves forward. Two people holding the roll material roll the roll material forward along the reference line at the same time. Note that the moving speed of the two persons lifting the coil should be the same and coordinated. It should not be too slack when rolling. After laying a roll of material, use a long-handled rolling brush to completely remove the air under the roll from the beginning, and then use a large pressure roller or a hand-held portable vibrator to press the roll. Really, stick firmly. Paving of facades and large slopes: Since the adhesive force between self-adhesive coils and the base layer is relatively low, the coils are prone to slide down on the facades or large slopes, so on the facades or large slopes During pasting construction. After the initial paving is completed, it is advisable to use a handheld gasoline torch to properly heat the adhesive on the bottom of the coil before pasting, venting or rolling. Use a welding machine to weld each lap edge. If double welds are used, air inflation testing is required. Detailed nodes. The coil sheet of the corresponding node is welded to the large-surface coil using a hand-held welding gun. There are many construction methods for waterproofing membranes, such as cold bonding method, hot air welding method, hot melt method, self-adhesive method, etc. Internally reinforced waterproof membrane manufacturers: Why are waterproof materials incessant after repeated bans, and even intensified? Industry insiders believe that overcapacity and ineffective supervision are two important reasons: On the one hand, there is a market where there is demand, and high profits make backward overcapacity lead to companies taking risks.
