Graphite Water-Resistant Board

A: It is usually made of high-density polyethylene (HDPE) or modified plastic as the base material, with graphite particles added to enhance the waterproof performance, and the surface may be covered with a protective film or anti-slip layer.

A: It is suitable for projects that require long-term waterproofing, such as basements, tunnels, bridges, pools, roofs, etc., especially for complex structures or chemical corrosion environments.

A: It can generally reach 30-50 years, depending on the environment (such as ultraviolet rays, chemical corrosion, etc.).

A: It is recommended that large projects be constructed by a professional team, and small areas can be DIY, but attention should be paid to joint treatment (such as hot melt welding).

A: Use a special welding machine for hot melt connection to ensure that the joints are seamless and avoid water leakage hazards.

A: Advantages: Corrosion resistance, puncture resistance, long life, environmental protection and recyclability.
Disadvantages: High cost, hard materials may need to be used with a protective layer.

A: Some products contain an anti-ultraviolet layer, but long-term exposure may age, so it is recommended to cover the protective layer (such as soil, concrete).

A: Minor damage can be treated with special repair glue or patch sheets; large-area damage requires replacement of local panels.

A: Graphite sheets are more durable, environmentally friendly, and more convenient to construct (no open flames are required), but the initial cost is high.

A: The conventional thickness is 1.0-2.0mm, which is selected according to the project requirements (such as hydrostatic pressure, chemical corrosion). Important projects recommend ≥1.5mm.

A: Lightweight materials (density of about 0.95g/cm³) have little impact on structural loads and are suitable for lightweight design.

A: It can be detected by electronic leak detector or inflation method, and observe whether there is any sign of water seepage at the joints on a daily basis.

A: Check once every 5-10 years, focusing on the joints, fixings and surface wear, and cleaning the drainage system.

A: Most products are B1 grade flame retardant materials, which will extinguish themselves when away from fire, but direct contact with open flames should be avoided.

A: Avoid puncture with sharp objects, store in a cool and dry place, and prevent direct ultraviolet rays and high temperatures.

A: It is suitable, but it needs to be combined with finishing materials such as tiles, and pay attention to construction details (such as floor drains and pipe surrounding treatment).

A: The temperature resistance range is usually -40℃ to 80℃. The flexibility may decrease at low temperatures. It is recommended to choose a cold-resistant model.

A: It can be used with a root-resistant puncture layer, and the load and drainage design must be considered.

A: The material can be 100% recycled and meets environmental protection standards. After disposal, contact the manufacturer or professional organization for disposal.

A: Flexible materials can adapt to certain deformations, but large-area settlements require expansion joint design.
