What is the difference between water storage drainage board and ordinary drainage board?

Storage and drainage board is a board that can both store and drain water, commonly used in fields such as roof greening and indoor planting. ‌ It is made of ‌ high density polyethylene (‌HDPE) or ‌ polypropylene (‌PP) and has the integrated function of waterproof, water storage and drainage. Through its special structural design, the storage and drainage plate can store water when needed and quickly discharge it when it needs to be drained. It can effectively prevent water accumulation inside the building and ensure the quality and safety of the building.

‌‌Drain board is a new type of building material, mainly used to form a protective barrier between the building and the soil. It can prevent water and acid and alkaline substances in the soil from eroding the building surface. ‌ drain plates are made of ‌ polystyrene (HIPS), polyethylene (‌HDPE) or ‌ polyvinyl chloride (‌PVC). A conical protrude or reinforced convex point is formed by machine stamping to improve its compressive strength and overall flatness.

drainage board and storage board are widely used in construction engineering, and they each have unique functions and characteristics to meet the needs of drainage and water storage in different scenarios. This article will discuss in detail the main differences between the drain plate and the storage drain plate.

Function:

First of all, from the functional point of view, the main function of the drainage board is drainage and moisture-proof. It is specially designed to effectively collect and expel water, preventing it from penetrating and damaging the building. Drainage panels are widely used in indoor and outdoor ground, wall and roof drainage projects to provide effective waterproof protection for buildings. In addition to the function of drainage, the storage and drainage plate also has the function of water storage. It can store a certain amount of water, providing sufficient water and oxygen for plant growth. The storage and drainage board is mostly used for roof greening, roof greening and other scenes, which helps to create a green and ecological living environment.

Structure:

From the point of view of structural characteristics, the drainage plate is usually designed with concave-convex structure, and the raised part can improve the bearing capacity of the drainage plate and increase its stability. The sunken part can effectively collect and discharge water to avoid water accumulation. The storage and drainage plates are heated and pressurized to form a drainage channel with a certain spatial support stiffness. The plate has the characteristics of extremely high spatial stiffness and can withstand greater pressure and load.

Materials:

From the material point of view, the material of the drainage board is mostly waterproof materials such as polyethylene (HDPE) or polyvinyl chloride (PVC), which has excellent weather resistance and corrosion resistance. The storage and drainage plates are made of high-density polyethylene (HDPE) or polypropylene (PP).

Construction:

There are also differences in construction difficulty between drainage plate and storage drainage plate. The construction of the drainage board is simple, and two workers can quickly lay a large area, and the construction difficulty is relatively low. As the storage and drainage board needs to take into account the water storage function, its construction process may be relatively complex, requiring more skills and precautions.

Cost:

In terms of cost, because the storage board has more functions and a more complex structure, its price is usually higher than that of the drainage board.

Application:

From the application scenario, the drainage board is widely used in various buildings and infrastructure projects, such as roads, Bridges, tunnels, airports, etc., because of its excellent drainage and moisture-proof performance. The storage and drainage board is more used in scenarios where drainage and water storage problems need to be solved at the same time, such as roof greening and indoor planting.

Summary：

There are obvious differences between the drainage board and the storage drainage board in terms of function, structural characteristics, construction and cost, and application scenarios. When choosing which plate to use, it should be comprehensively considered according to specific needs and scenarios to ensure the quality and effect of the project. At the same time, with the continuous progress and innovation of technology, the performance and application range of these two plates may be further expanded and optimized in the future.
