DIMPLE MEMBRANE
Dimple membranes are a type of geosynthetic material that consists of a sheet of plastic with a series of raised, dome-shaped protrusions (dimples) on one or both sides. These dimples create a void space between the membrane and the underlying soil or structure, which can have several beneficial effects.
KEY FUNCTIONS
Drainage
The dimples create a drainage channel, allowing water to flow freely through the soil and preventing waterlogging.
Separation
The dimples can act as a barrier, preventing the mixing of different soil layers or materials.
Protection
The dimples can protect underlying structures from damage caused by point loads or concentrated stresses.
Reinforcement
In some applications, dimple membranes can provide additional strength and stability to soil structures.
Common Applications of Dimple Membranes
Road construction
Used as a subbase layer to improve drainage and prevent frost heave.
Railroad tracks
Used to improve drainage and reduce track maintenance.
Airports
Used to prevent pavement failures and improve drainage.
Landfills
Used to control leachate and prevent groundwater contamination.
Roof gardens
Used to improve drainage and prevent root penetration.
Benefits of Using Dimple Membranes
Helps to prevent waterlogging and erosion.
Can help to improve the stability of soil structures.
Can reduce the need for costly maintenance and repairs.
Can help to protect groundwater and prevent pollution.
