PRODUCT DETAILS
What is Black Garden Drainage Board?
Black Garden Drainage Board, also known as "PP plastic Black Garden Drainage Board", is a type of fast filtering water board. Its products are mainly made of high toughness and high strength polypropylene injection molding, with high compressive strength, no deformation, and no cracking.
Black Garden Drainage Board has good permeability, large displacement, simple and fast construction, good safety, and is suitable for underground drainage, large-area wall drainage, etc.
PP Black Garden Drainage Board is a functional material with many potential functions. The use of this board can easily construct an elevated layer, forming drainage and exhaust channels through the elevated layer. Similarly, the use of the elevated layer can achieve sound insulation and vibration isolation functions. Black Garden Drainage Boards can be widely used in the field of civil engineering, such as intra layer overhead of building roof systems, drainage and ventilation of planting roofs, waterproofing of building basements, drainage protection of systems, moisture-proof and thermal insulation protection of indoor floors, and drainage and waterproofing of highway and railway tunnels.
1. Greening projects
Garage roof greening, roof garden, vertical greening, sloping roof greening, football field, golf course.
2. Municipal engineering
Airports, road embankments, subways, tunnels, landfill sites.
3. Construction engineering
Upper or lower layers of building foundations, indoor and outdoor walls and baseplates in the basement, as well as top plates, roof anti-seepage and insulation layers.
Benefits of PP (Polypropylene) Black Garden Drainage Board：
1. High resistance to plant root thorns.
2. This adds a layer of waterproof guarantee to the long-lasting and complete protection of the building structure and waterproof layer, playing a secondary auxiliary waterproof role.
3. High compressive performance.
4. The unique wide design has a width of up to 3 meters, minimizing overlap and loss, saving time and materials, and construction is not limited by temperature in any season.
5. High strength and good toughness, it can easily create a three-dimensional overhead layer within the layer, with low cost and significant effectiveness.
6. Strong corrosion resistance.
Drainage Board / Dimple Sheet FAQs
1) What is a drainage board (dimple sheet)?
Drainage boards (dimpled drainage boards) are manufactured from high-density polyethylene (HDPE) through a stamping process. Their surfaces feature a regularly arranged pattern of dimples, which effectively isolate the soil and create a permanent, continuous drainage space, thereby providing exceptional waterproofing, anti-seepage, and water-conducting capabilities.
2) Where is dimple sheet used in construction?
It is widely applied in the landscaping of basement roof slabs, waterproofing of basement exterior walls, roof gardens, the base slabs of road and railway tunnels, and various retaining wall drainage projects; it effectively alleviates water pressure and protects the main building structure from groundwater erosion.
3) What thickness and compressive strength should I choose?
Product selection should be determined based on the project's depth and load requirements. For standard basement walls, products with a stud height of 10–20 mm are typically used. However, if the backfill is particularly deep or the roof slab is subject to heavy loads (such as those imposed by landscaping or planting), it is recommended to select drainage boards made from virgin material—characterized by high gram weight and high compressive strength—to prevent deformation.
4) Does drainage board replace a drainage composite?
Dimpled drainage boards typically require pairing with geotextiles to achieve optimal filtration and drainage results. In contrast, composite drainage materials—such as drainage boards laminated with geotextiles—constitute integrated products. In specific light-load applications or spaces dedicated solely to water conveyance, drainage boards may be utilized as a standalone alternative.
5) How do you install dimple sheet on basement walls?
Wall installation must proceed from the bottom up, with the dimples facing the wall surface. Secure the material using specialized insulation anchors or shot-fired fasteners fitted with washers. Overlapping sections should be sealed using double-sided tape or heat welding, and the top edge must be secured and sealed with a finishing strip to prevent silt and debris from entering the drainage channels.
6) What is the difference between HDPE dimple sheet and other plastics?
Compared to ordinary plastics, high-quality, brand-new HDPE material exhibits superior chemical stability, excellent resistance to acid and alkali corrosion, high tensile and compressive strength, and strong puncture resistance. It is highly resistant to aging and degradation in harsh, damp underground environments, ensuring an engineering service life of over fifty years.
