Bridge deck waterproofing

ZX-FS-06 Polymer-modified asphalt Bridge deck waterproofing is a kind of high-molecular waterproof coating based on petroleum asphalt and compounded with various high-polymer modified materials. After reasonable proportioned, it can form a cross-linked polymer coating film with excellent performance after curing. It not only has the good waterproof characteristics of high-polymer cross-linked polymerization, but also has the good anti-aging and anti-corrosion performance of asphalt. After drying at room temperature, it can form a high-quality waterproof elastic film, which can adhere to a damp base surface. It is pollution-free, odorless, non-flammable and easy to apply.

Based on petroleum asphalt, it is compounded with multiple polymer modified materials

The characteristics of Bridge deck waterproofing

1. Appearance: After stirring, it becomes a black homogeneous liquid, and the waterproof coating has no visual particles.

2. Strong bonding performance: It has excellent bonding performance on the surfaces of concrete, steel structures and asphalt concrete in roads and Bridges, and can be directly applied on damp and non-standing water base surfaces. The coating film is based on asphalt-based materials, which can penetrate the asphalt concrete pavement for a long time and enhance the mutual adhesion.

3. Strong elongation performance: After the coating film is fully dry, it has high elasticity and strong cohesion within the film, which endows the waterproof coating film with certain self-healing properties.

4. Anti-aging performance: As the material is based on asphalt, the formed waterproof coating film has excellent acid resistance, alkali resistance and anti-aging performance.

5. Environmental friendliness: Cold construction is adopted, and mechanical spraying operation can be used, which is simple, convenient, fast and efficient, and friendly to the environment.

The application of Bridge deck waterproofing

1.Road construction: Waterproof coatings for roads and Bridges have extensive applications in road construction. It can be applied to the base layer, surface layer of roads and the bridge deck of Bridges, etc., to enhance the waterproof performance of roads and prevent water seepage from causing damage to the road structure.

2. Bridge Construction: In bridge construction, waterproof coatings for roads and Bridges also play a significant role. It can be applied to the bridge deck, piers and other parts of the bridge to prevent water from eroding the bridge structure and ensure the safety and service life of the bridge.

3.Tunnel construction: Bridge deck waterproofing also play an important role in tunnel construction. The interior of the tunnel is humid and prone to moisture erosion. The application of waterproof coating for roads and Bridges can effectively prevent water penetration and protect the safety of the internal structure of tunnels.

1.Before the final setting of the bridge deck concrete, a regular and uniform roughening treatment is carried out on the concrete surface, which has a good effect.

2. The waterproof layer construction can only be carried out when the concrete strength of the bridge deck reaches at least 70% of the designed strength.

3. Bridge deck expansion joints, anti-collision wall expansion joints, bridge deck drainage outlets, etc., shall be treated separately in accordance with the waterproofing design of the bridge structure.

4. The construction temperature is preferably between 5℃ and 35℃. Construction is not allowed when the temperature is below 5℃ or on rainy days (including when it is expected to rain within 6 hours after construction).

5. Do not walk on or drive vehicles until the waterproof layer is completely dry, and prevent sharp objects from scratching the waterproof layer.

ZX-FS-06 Packaging, transportation and storage

1.Packaging: The product is packaged in plastic drums with an internal sealed bag, with a net weight of 50kg per drum
