The research on exterior wall waterproofing in China is still in its infancy.
Jinshuai waterproof supermarket can meet the waterproof needs of different regions, different forms and different structural parts, and use high-quality products to serve high-quality projects.
However, many bridges are not waterproof or adopt improper waterproof materials, resulting in serious damage problems such as water seepage, reinforcement corrosion, pavement peeling, alkali aggregate reaction, concrete expansion and cracking caused by reinforcement corrosion, which seriously affect the firmness and service life of the bridge, driving comfort and safety.
External wall waterproofing has not been paid attention to all the time, because its leakage and impact caused by leakage are smaller than those of roof, underground engineering, toilet and other parts.
What are the main waterproof projects according to the division of project parts? 01 roof waterproofing works roof waterproofing refers to preventing rainwater from invading the room from the roof.
In recent 20 years, a large number of urban long-span bridges, viaducts, overpasses and other urban bridges have been built in large and medium-sized cities such as Beijing, Shanghai, Tianjin and Guangzhou, and high-grade highways such as expressways and first-class highways have increased by more than 10000 kilometers every year.
Sometimes, it is required to prevent not only leakage, but also erosion of acid-base liquid, especially for chemical production workshops.
Therefore, in addition to the waterproof (liquid) capacity of the water storage (liquid) tank structure itself, the waterproof layer is generally set inside, and the waterproof materials required to be used will not pollute the water quality (liquid) or be corroded by the liquid storage.
Jinshui waterproof supermarket covers SBS, self-adhesive, high polymer polyethylene polypropylene (polyester) fiber waterproof coiled materials, waterproof coatings, waterproof accessories and other products, basically realizing the full satisfaction of products and full coverage of functions.
Now there are requirements for comprehensive utilization of roofs, such as activity places, parking lots, roof gardens, water storage and heat insulation, planting roofs, etc.
Most of them use inorganic materials, such as polymer mortar and cement-based waterproof materials.
Due to the complex structure and special construction method of underground engineering, due to the infiltration and erosion of surface water, groundwater and capillary water, as well as the influence of nearby hydrogeological changes caused by human factors, its waterproof fortification, waterproof construction, maintenance and management are more difficult and demanding.
Toilets and some production workshops have many pipes and equipment, concentrated water consumption, serious splashing and a lot of acid-base liquid.
(some articles come from the Internet) thank you for reading this article 11 patiently-.
02 toilet and floor waterproofing works toilet and floor waterproofing is to prevent domestic and production water and domestic and production sewage from leaking downstairs or penetrating into other rooms through partition walls.
In recent years, people’s understanding of the importance of waterproof of urban roads and bridges has become increasingly clear.
In the selection process of waterproof materials, according to the actual situation of buildings, the most appropriate materials and the best scheme are selected according to local conditions.
05 waterproof works of water storage tanks and water structures the waterproof of water storage tanks and liquid storage tanks is to prevent water or liquid from leaking outward, and those located underground should also prevent groundwater from penetrating inward.
Under what conditions, the waterproof fortification of exterior wall, the waterproof fortification structure of different structures and wall materials, and the further development of waterproof materials suitable for exterior wall need more research and summary.
However, with the improvement of people’s requirements for production and living environment and the reduction of leakage rate of roof and underground engineering, the importance of exterior wall waterproof is becoming more and more obvious.
Underground engineering waterproof is the technical work of waterproof design, waterproof construction, maintenance and management of underground engineering.
In the daily building construction, waterproof construction is an important project.
04 external wall waterproofing works external wall waterproofing refers to preventing rainwater or external wall cleaning water from penetrating into the room.
More and more bridges begin to adopt deck waterproof system.
these houses have higher requirements for waterproof layers.
03 underground waterproof works underground works refer to industrial and civil buildings, underground works, protection works, municipal tunnels, mountain and underwater tunnels, caverns, underground railways and other buildings and structures.
With the deepening of China’s reform and opening up, the traffic facilities all over the country have developed rapidly.
