The sampling layer of elastomer modified bitumen waterproof membrane is made flexible waterproof, that is, special anti-aging waterproof coating for roofing. The second layer is made of mortar waterproof (mortar waterproofing agent), which can protect the flexible waterproof of the bottom layer while waterproofing. A single waterproof material cannot be used for roof waterproofing. It must be constructed in a combination of rigid and flexible. The flexible waterproof stretch has good stretchability, and a slight settlement or deformation will not damage the waterproof layer. Rigid waterproofing (that is, mortar waterproofing agent) can play a protective role at the same time, and the waterproof layer is not easy to be damaged.
A buffer layer is set at the seam of the end of the prefabricated roof panel, and the width of the dry-laid coil is 300mm. It is not advisable to stretch the coil too tightly. In summer, the construction should be relaxed and then laid. When the waterproof membrane has cracks, use a cutting machine to cut along the regular crack spring line. If there is no split seam in the base layer, the seam should be cut, the seam width is 20mm, the seam is filled with flexible sealing paste, a 200mm wide roll of material is laid along the seam as a buffer layer, and then a 350mm wide roll is fully glued The treatment methods for the detailed cracks of the waterproof layer and joints are the same as above.

Elastomer-modified bitumen waterproof coiled material sampling protection layer must be passed after the waterproof layer is accepted before construction: clean the surface of the waterproof layer: protect the coiled material of the construction material transportation channel: the construction personnel should wear soft-soled shoes to operate. Other matters needing attention. The construction temperature of polymer waterproof membrane should be above 5℃ and below 25℃. It is forbidden to use cement glue when the ambient temperature is 0℃ and below, and polyurethane glue is not allowed when the ambient temperature is -5℃ and below. When using polyurethane glue, it is forbidden to use solvent to dilute to prevent the coil from swelling and deforming.
High-quality road asphalt and tackifier as the base material, using polyester film (PET), polyethylene film (PE), aluminum foil or silicon-coated isolation film as the upper surface material, and the lower surface is covered with silicon-coated isolation film as the anti-sticking layer. The self-adhesive polymer modified asphalt is made of tireless waterproofing membrane. Self-adhesive waterproof material has good weather resistance, has a certain endurance to light, hot ozone, etc., has good water penetration and acid and alkali resistance, and is adaptable to temperature and external forces, that is, the waterproof material has high tensile strength. The elongation at break should be large, and the waterproof material can withstand changes in temperature and various external forces and the deformation caused by the expansion and cracking of the base layer, and the integrity is good. The self-adhesive polymer modified bitumen waterproofing membrane is made of synthetic rubber such as SBS, which can not only maintain its own adhesion, but also firmly bond with the base layer. At the same time, under the action of external force, the waterproof material has a higher peel strength, forming Stable and impervious overall.
Pay attention to the product name and packaging mark. According to product standards, the outer packaging of the product should be marked with the company name, product mark, production date or batch number, production license number, storage and transportation precautions, and the product marking should be strictly in accordance with the standard, consistent with the product name, and must not be ambiguous Incomplete words or marks and no production marks. When choosing these products, users must pay attention to the product label and recognize the product name, because the label represents the identity of the product. After all, the main base for sloping roof drainage is generally waterproof construction. The horizontal width of the building surface is divided by vertical and horizontal as the mainstream domain. The drainage slope must be greater than the watershed between 2% and 3%, in order to reduce the water of the roof. In the use of waterproof construction, we are mainly concerned with the length and height of the waterproof construction paving, which can give the building waterproof and leak-proof effects. For example, the retaining wall and raft on the border need to use an extra layer of waterproof material. Generally speaking , Normal waterproof material, about 300 mm should be spread on the wall, and wall waterproofing agent also needs to be laid on the wall about 1,800 mm. Detailed explanation of the thickness of the additional layer of waterproofing membrane. We have to choose a waterproof material for the roof slope, and we must do a good design and start to have a better waterproof effect.
Hydrostatic pressure can also make small defects a source of leakage. Underground waterproofing is a vital part of construction projects and home improvement projects. If the waterproofing of the basement is not done well, it is prone to water leakage and water seepage, causing serious economic losses. The basement is well-lit, and there is not much sunlight throughout the year. If there is water leakage, it is easy to cause mold in the indoor objects. Generally, electrical switchgear is located in the basement, so the requirements for waterproofing are particularly high, so focus on waterproofing the basement. .
The overall performance of the product is good, and it meets the requirements of environmental protection and safety. The physical and mechanical performance indicators of the current product standards have reached the international level. The construction method recommended by the industry can guide the construction work. Such coils and application technologies that meet the basic requirements can reach international standards. Shandong waterproofing membrane has good effect and is worth buying. The company's products are sourced from the Hebei branch and the Shandong branch. We learn from each other's strengths to make up for the shortcomings, which greatly saves the cost of products and realizes the high quality and low price of the products. To a certain extent, it guarantees sufficient supply and rapid delivery. The concealed pipe of the upper water pipe is not installed properly, the water pipe is inferior, and the galvanized pipe is rusty and aging, which may cause water leakage. If the water leakage is caused by the rust and aging of the galvanized pipe, the galvanized pipe can only be installed in the leaking place, and the galvanized pipe is easy to be corroded, so it is better to replace all the galvanized pipes. The waterproof layer of the light-body wall in the shower area is not up to meters high, and the light-body wall is easily damp in the damp environment all year round. For the health and safety of the home, it is recommended to knock off the wall tiles and re-waterproof it.
