Dimpled Drainage Board with Geotextile for Garden Roof

Dimpled drainage board with geotextile, also called sheet drain, is manufactured from high density polyethylene heat bonded to polyester or polypropylene nonwoven geotextile fabric available in one single configuration.

1 What is Dimpled Drainage Board?

Dimpled drainage board is a type of membrane used for drainage and filtration purposes in various civil engineering projects. It consists of a sheet with raised dimples or studs on one side, and a geotextile cloth or fabric on the other side. The dimples create an air gap between the membrane and the surface it is applied to, allowing for effective drainage.

The primary function of dimpled drainage board is to provide a drainage path for water. When installed correctly, the dimples create channels that allow water to flow freely, preventing water buildup and reducing hydrostatic pressure. This is particularly useful in applications such as retaining walls, landscaping drainage, parking decks, basement walls, and tunnels, where effective drainage is essential to maintain structural integrity and prevent water damage.

The geotextile cloth or fabric attached to one side of the dimpled drainage board serves as a filtration layer. It helps to prevent the entry of fine particles, soil, or debris into the drainage system, ensuring that the water passing through the membrane remains clean and free from clogging.

BPM dimpled drainage boards are designed to be durable and resistant to compression, making them suitable for various construction projects. They provide an effective solution for managing water drainage, reducing the risk of water-related issues such as seepage, dampness, and structural damage.

3 Why Chose Dimpled Drainage Board with Geotextile for Garden Roof

Choosing dimpled drainage board with geotextile for a garden roof offers several benefits and can effectively address various issues related to waterproofing, drainage, and protection. In the case of your Pakistan customer’s inquiry for 17,000 square meters of drainage sheeting for a roof garden, BPM dimpled drainage board with geotextile is a suitable solution.

1. Waterproofing: The dimpled drainage board acts as a waterproofing layer by providing a barrier that prevents water from seeping into the underlying structure. It helps to protect the roof and the building from potential water damage caused by rain, irrigation, or other sources of water.

2. Drainage: The dimples in the drainage board create a channel for water to flow, ensuring effective drainage. Excess water from rain or irrigation is directed away from the roof surface, preventing water buildup and potential waterlogging issues. This helps to maintain a healthy and functional garden roof by preventing water-related damage and promoting proper plant growth.

3. Protection: The geotextile layer attached to the dimpled drainage board provides an additional protective function. It helps to prevent the penetration of fine particles, debris, or roots into the drainage system, ensuring its long-term functionality and preventing clogging. The geotextile also acts as a protective barrier for the underlying roof surface, reducing the risk of damage from physical impacts or abrasion.

4. Enhanced Garden Performance: By utilizing dimpled drainage board with geotextile, the garden roof can achieve better performance. Effective drainage and waterproofing create a favorable environment for plant growth, preventing waterlogging and excessive moisture accumulation, which can lead to root rot and other plant health issues.

5. Longevity and Maintenance: The use of dimpled drainage board with geotextile can contribute to the longevity of the garden roof. It helps to protect the roof structure from water-related damage, reducing the need for costly repairs or replacements. Additionally, the geotextile layer reduces the maintenance required for the drainage system by preventing the entry of debris, roots, or soil particles that could potentially clog the system.

In summary, selecting dimpled drainage board with geotextile for a garden roof provides effective waterproofing, drainage, and protection. This solution can address various issues related to water management and enhance the performance and longevity of the garden roof.
