Product overview
The EVA waterproof board is made up of automatic production line by calendering process,which is formed by one molding process.. Using high quality ethylene vinyl acetate copolymer as the main raw material, adding fiber to increase strength; adding modifier to improve material physical and chemical properties; adding stabilizers to improve chemical and physical stability; adding antiaging agents to prolong material life; adding antioxidants to improve antioxidant energy supply; adding fungicides to prevent bacteria and molds Bacterial erosion.
Product performance
* High tear strength, waterproof and impermeable, good hydrolysis resistance.
* Specially adding antimicrobial agent to the material to prevent the erosion of microorganism and prolong the service life of the product effectively.
* Good root puncture resistance, especially suitable for planting roof.
* There is no special requirement for the water content of the base, so long as there is no clear water, normal construction can be done, and there is no effect on the construction quality.
* It has good aging resistance and can be used for more than 50 years when buried underground.
* Good flexibility at low temperature even at -3℃.
* Simple construction, safe and environmental protection, saving time limit and reducing cost.

Construction technology
* Base requirements: cleaning the laying surface, requiring leveling, the soil is solid, no uneven and sharp objects.
* The welding joint treatment of the waterproof board is the key procedure of construction. Generally, the heat welding method is used, the jointed surface of the EVA waterproof plate is with heating treatment, and then the melt is synthesized through the pressure.
* For the laid of waterproof boards, there is no oil, water and dust at the edge joints.
* Before welding, adjust the two sides mold to make sure that it has a certain width. the width of the joint is generally 70mm, and it is smooth without wrinkle, using a professional welding machine.
Application Range
* Traffic engineering: waterproof and seepage prevention works such as tunnels, subways, highways, caverns, bridges, etc.
* Construction engineering: waterproof and seepage prevention works such as roofs, basements and others.
* Water conservancy works: waterproof and seepage prevention works such as reservoir dams, cofferdams, drains, etc.
* Environmental protection works: landfill, sewage treatment plant, metallurgical chemical engineering, etc.
* Other works requiring waterproof, impervious and moisture-proof treatment
Transport and storage
* The coil should be stored in a dry and ventilated environment, and protective measures should be taken to avoid sun and rain.
* During transportation, products of different types and specifications should be stacked in categories and can’t be mixed up; far from heat sources, no contact with acid, alkali, oil and organic solvents.
* During transport, it should be placed horizontal or vertical to prevent tilt, pressure and if necessary, cover with felt cloth.
* Storage temperature not exceeding 45℃, height of amplifier not exceeding 5 layers.
* Under normal storage and transportation conditions, the storage period is 12 months from the date of production. Once exceed the storage period, the products can also be used normally after passing the inspection.
