Drainage boards are essential geosynthetic materials designed to enhance drainage and reduce excess pore water pressure in soil and construction environments. Typically made from high-density polyethylene (HDPE) or similar plastics, they feature a three-dimensional profile that creates channels for water flow. These channels allow for the efficient collection and drainage of water, preventing waterlogging and improving the stability of engineered systems. Drainage boards are manufactured through a process that involves extruding the plastic material into a specific shape and then bonding it to a filter fabric. The filter fabric prevents soil particles from entering the drainage channels, maintaining the long-term functionality of the drainage system. Drainage boards are widely used in various civil engineering and construction applications to address water management challenges.
High Drainage Capacity: The unique three-dimensional structure of drainage boards creates continuous drainage channels that facilitate the rapid flow of water. This ensures efficient water discharge and reduces the buildup of water pressure within soil masses.
Excellent Filtration Performance: The bonded filter fabric effectively retains soil particles while allowing water to pass through. This prevents clogging of the drainage channels and maintains the drainage efficiency of the system over time.
Mechanical Stability: Drainage boards provide additional mechanical reinforcement to the surrounding soil. Their presence increases the soil's shear strength and stability, reducing the risk of settlement and failure in construction projects.
Corrosion Resistance: Made from inert plastics like HDPE, drainage boards are resistant to chemical corrosion and biological degradation. They can withstand long-term exposure to various soil and water conditions without deteriorating.
Easy Installation: Drainage boards are lightweight and flexible, making them easy to handle and install. They can be laid out quickly over large areas and adapted to different site geometries, reducing installation time and labor costs.
Cost-Effective Solution: By improving drainage and soil stability, drainage boards help prevent costly repairs and maintenance associated with water-related damage. Their relatively low cost and ease of installation make them a cost-effective solution for water management.
Foundation Engineering: Drainage boards are used in building foundations to prevent water accumulation and reduce hydrostatic pressure against basement walls and foundation slabs. This helps prevent water infiltration and protects structural integrity.
Road and Highway Construction: They are installed beneath road bases and embankments to drain excess water from the subgrade, improving road stability and reducing the risk of pavement deformation and potholes.
Railway Engineering: Drainage boards help drain water from railway subgrades, preventing track settlement and maintaining the stability of railway tracks. This ensures safe and efficient railway operations.
Landfill Construction: In landfill projects, drainage boards are used to drain leachate and rainwater from within the waste mass and the surrounding soil. This helps control leachate levels and prevents contamination.
Slope Stabilization: Drainage boards are applied in slope stabilization projects to drain water from within slopes, reducing pore water pressure and the risk of slope failures. They enhance slope stability and safety.
The product has a three-dimensional dimple structure. The dimples form channels for water flow, which can efficiently collect and discharge excess water in the soil or construction structure. The bonded filter fabric can prevent soil particles from entering and clogging the drainage channels.
The dimple heights of the High-Flow HDPE Dimple Drainage Board include 8mm, 10mm, 12mm and 20mm, and the board thickness ranges from 0.8mm to 2.0mm to meet different drainage flow requirements.
It is widely used in foundation engineering (reducing hydrostatic pressure on basement walls), road and highway construction (draining subgrade water), railway engineering (maintaining track stability), landfill construction (leachate drainage) and slope stabilization projects.
