With changes to regulations and the demands of various design institutes, as well as the high standards of the construction industry for buildings, the drainage board market is heating up. Many customers are opting for rolls, while others have doubts: should the roof of an underground parking garage use a drainage board or a water-retaining board?

One, drainage boards effectively prevent and drain water, whereas water retention boards can only drain water.

The former effectively prevents plant thorns, whereas the water-retaining boards do not.

The former's installation process is extremely simple, significantly reducing labor costs. The drainage panels, sold directly by the manufacturer, come in rolls of 30 square meters. The installation rate can reach nearly 2,000 square meters per day, whereas the water-retaining panels are sheet materials with a slower installation speed, only one-fourth of the roll material's rate per day.

Four, the former has a very high load-bearing capacity, which is highly suitable for situations requiring soil backfilling followed by vehicle passage. Shengqiu New Material Technology recommends using drainage boards here.

The top surface of the conical pier is bonded with a layer of filtration geotextile to prevent soil particles from passing through, thereby avoiding blockages in the drainage channels and ensuring smooth water drainage. Traditional drainage methods employ bricks, tiles, and a large amount of cobblestones as filter layers.

Using crushed stone as a water filtration layer and draining water to the designated locations. Replacing the gravel filtration layer with it for drainage saves time and effort, conserves energy, reduces investment costs, and also lessens the load on the structure.

A well-designed drainage system plays a crucial role in the construction timeline and the normal use and lifespan of structures. It, along with porous drainage pipes, forms an effective drainage and drainage system. The cylindrical hollow drainage boards, along with geotextiles, also constitute a drainage system, thereby creating a system with functions of渗水 (seepage), 贮水 (storage), and 排水 (drainage).

Our drainage boards are suitable for use in green roofs for garages, roof gardens, vertical greenery, sloping roofs, soccer fields, golf courses. They are also ideal for airport runways, road subgrades, subway tunnels, landfill sites. They can be utilized for the upper or lower layers of building foundations, interior and exterior walls and slabs of basements, as well as waterproof and thermal insulation layers on roofs. They are effective for reservoirs, water storage ponds, and artificial lakes. Additionally, they are used for highway and railway subgrades, embankments, and slope protection layers.

That concludes the differences between drainage boards and water retention boards. Drainage protection boards effectively safeguard structures and waterproof layers, and resist various acidic and alkaline substances in the soil as well as plant root thorns. During the backfilling of soil against the exterior walls of basements, they protect the buildings and waterproof layers from damage.
