　　HM-1500Bridge deck waterproofing agent

　　Product description

　　The "Shuanghong" brand HM-1500 bridge deck waterproofing agent is a new type of green water-based permeable inorganic waterproofing agent. It has extremely strong permeability, can penetrate more than 4cm below the cement concrete and have secondary chemical reaction with alkali substances in the cement concrete, generate water insoluble gel, fill the small pores and gaps in the cement concrete, seal the capillary channels, form a complete, ideal and efficient waterproof base material as a whole, so as to play a waterproof role, and also have the effect of weathering resistance and corrosion resistance.

　　Product advantages

　　1. HM-1500 bridge deck waterproofing agent is a non-toxic, odorless, non flammable inorganic water-soluble material that is safe to construct and not prone to aging. It is a water-based waterproofing material;

　　2. Has strong infiltration and diffusion ability, can penetrate into cement concrete structures by more than 40mm, seal the capillary channels inside the structure, form a complete and dense waterproof layer, protect the steel bars inside the reinforced concrete from corrosion, and play a good role in waterproofing, impermeability, and sealing;

　　3. It can make the new concrete (mortar) solidify evenly, prevent early water loss and local cracking, thereby improving curing conditions and increasing strength.

　　4. It can improve the compactness of cement concrete, increase the strength of the concrete surface layer (generally, the strength of the permeable layer can be increased by more than 10%), thereby improving the carrying capacity of cement concrete bridge decks.

　　5. It can improve the surface carbonation resistance and acid and alkali resistance of cement structures (components), and has functions such as mold prevention, anti-corrosion, acid and alkali resistance, weathering resistance, and prevention of moss growth.

　　6. Large areas can be constructed using spray coating method, which is simple, convenient, and refreshing. The formed waterproof layer is not affected by changes in external temperature, and will not crack or break. It has a strong waterproof leakage effect and does not affect the operation of the next process.

　　Scope of Application

　　This product is widely used for waterproofing, anti-corrosion, and reinforcement of many domestic highway bridges, municipal elevated bridges, and building (basement) structures. Users include many large-scale projects such as Nanning Outer Ring Road, Jingna Expressway Company, Yutie Expressway Wangmao Section, Maping Expressway, and Nanning Municipal Elevated Bridge.

　　construction technology

　　1. Grassroots cleaning

　　Before spraying HM-1500 bridge deck waterproofing agent, first chisel off the concrete slurry, level the uneven areas, remove oil stains, garbage, etc. Then thoroughly clean the base surface, and use a dust blower to blow off the floating dust on the base surface;

　　2. HM-1500 bridge deck waterproofing agent spraying

　　When HM-1500 waterproofing agent penetrates into the interior of the base layer and there is no obvious wet state on the surface, spray a second coat of waterproofing agent;

　　3. After the second coat of waterproofing agent is sprayed, a dedicated person should be responsible for observing the evaporation of the coating. After about 2~3h, when the waterproof agent coating is about to dry, water shall be sprayed with a spray immediately, depending on the wet surface, not too much to avoid loss of waterproof agent.

　　Reference dosage and precautions

　　1. The construction adopts machine spraying, which can cover 4-5 square meters per liter. The actual dosage depends on the specific substrate conditions.

　　1. The construction temperature should be between 0 and 35 ℃, and construction should not be carried out during rainy or freezing periods;

　　3. Do not mix this product with other materials.

　　Packaging, Storage, and Transportation

　　1. The outer packaging is in plastic drums.

　　2. During transportation and storage, products of different types and specifications should be stacked separately and not mixed together. Avoid direct sunlight and rain, and pay attention to ventilation.

　　3. Under normal transportation and storage conditions, the storage period is one year from the date of production.
