Storage and drainage board

What Is Storage and Drainage Board?

Storage and drainage board is a plastic dimpled sheet used in green roofs, underground garage floors, roof plate landscapes, retaining walls, and basement drainage protection systems. The raised dimples create a space for water storage and water discharge.

In a green roof system, the board is placed above waterproofing and below filter fabric and planting soil. It stores part of the water for plants and guides excess water toward outlets, helping reduce waterlogging in the roof garden layer.

For Underground garage floor protection and wall retaining projects, buyers should check dimple height, sheet thickness, compressive strength, flow capacity, filter fabric coverage, and outlet design. The board supports drainage and protection but does not replace waterproof membrane.

CHANGFENG can supply Green roof drainage board, Drain dimple waterproof board, and Subsurface storage drainage solution options with custom sheet size, color, packing, and OEM/ODM support.

Application Scenarios

1. Green Roof Drainage Board

The board stores part of the water for plants and drains excess water away from the roof garden system.

2. Underground Garage Floor

Above underground garage slabs, it can protect waterproofing and create a drainage path below soil or paving layers.

3. Retaining Wall Drainage

Behind retaining walls, the dimple structure guides water downward and helps reduce pressure on waterproofing layers.

4. Roof Plate Landscape Systems

For podium decks and roof plate landscapes, the board provides a lightweight alternative to heavy gravel drainage layers.

5. Basement and Foundation Protection

Drain dimple waterproof systems can be placed near basement walls or foundations where water needs a path toward outlets.

Quality Control

CHANGFENG checks Storage and drainage board by raw material, sheet size, dimple height, thickness, compressive response, edge condition, and appearance. For waterproofing projects, consistent dimple shape is important for drainage space and protection performance.

Project orders can include sample confirmation, labels, packing photos, loading records, and test documents. Special compressive strength, color, or sheet size requirements should be confirmed before production.

Packing and Delivery

Storage and drainage board is stacked or rolled according to product structure and order requirement. Packages can be wrapped with film, strapped, palletized, or grouped by project area. Labels can show sheet size, dimple height, quantity, batch number, and destination information.

FAQ

Q1: What is Storage and drainage board used for?

A: Folks use it for green roofs, basements, and underground garage floors. It fits nicely into roof plate landscapes, big retaining walls, and drainage protection systems.

Q2: How does Drain dimple waterproof board work?

A: The dimple structure simply creates small gaps. These hold a little water, then quickly push all the extra rain directly into the outlets.

Q3: Is it suitable for green roofs?

A: Yes! A Green roof drainage board smartly manages plant water. Just add some filter fabric and drains to completely stop bad waterlogging.

Q4: Can it protect waterproofing?

A: Yes. Built right, it acts as a tough protective layer either beside or right over your waterproofing membranes.

Q5: Can dimple height be customized?

A: Yeah. We adjust the dimple height, sheet size, and thickness. You also easily pick the color, compressive grade, and packing.

Q6: What information is needed for quotation?

A: Just send the sheet size, dimple height, thickness, and total amount. Also tell us your application, destination port, and test needs.

Q7: Does it replace waterproof membrane?

A: No. It definitely helps drain water, but you still need an actual waterproof membrane for your complete waterproofing systems.
