The main functions of drainage boards include drainage, waterproofing, protection, sound insulation, ventilation and moisture-proofing, etc.

What is the function of drainage board?

1. Drainage function
The drainage board has excellent drainage performance and can quickly and effectively drain rainwater or other accumulated water. Its unique concave-convex structure provides a good drainage channel, allowing water to quickly pass through the drainage board and flow into the designated drainage system. This helps to reduce the damage of accumulated water to buildings, roads and other infrastructure, and improve the stability and durability of engineering structures.
2. Waterproof function
The drainage board not only has a drainage function, but also has a certain waterproof performance. It can be used as an auxiliary waterproof material and used in conjunction with a waterproof layer to form an effective waterproof barrier. The drainage board can effectively block moisture from penetrating into the building or soil, preventing water damage from occurring.
3. Protection function
During the construction process such as backfilling, the drainage board can protect the waterproof layer and other engineering structures from damage. Its sturdy structure and excellent physical properties enable the drainage board to resist the erosion of external factors such as acid and alkali substances in the soil and plant root thorns, thereby extending the service life of the engineering structure.
4. Sound insulation and ventilation and moisture-proof function
The drainage board also has the functions of sound insulation and ventilation and moisture-proof. Laboratory data show that drainage boards made of materials such as polyethylene (HDPE) and polyvinyl chloride (PVC) can effectively reduce indoor noise and play a good role in ventilation and moisture prevention. This helps to improve the indoor environment and increase the comfort of living and working.
5. Application fields
Drainage boards have a wide range of applications, including but not limited to:
Greening projects: garage roof greening, roof gardens, vertical greening, sloping roof greening, etc.
Municipal engineering: airports, roadbeds, subways, tunnels, landfills, etc.
Construction projects: upper or lower floors of building foundations, internal and external walls and bottom plates of basements, as well as top plates, roof anti-seepage and insulation layers, etc.
Water conservancy projects: reservoir anti-seepage, reservoirs, artificial lake anti-seepage, etc.
Transportation projects: highway, railway roadbed, embankments and slope protection layers, etc.
