Methods of bund construction

Depending on its function, its retaining height, the availability of construction materials, etc. a bund may be constructed of dredged or imported rock fill or quarry run, borrowed granular or cohesive fill material or just material available in the immediate vicinity of the bund. Very soft to soft clay or silt, however, is not a suitable construction material. Sometimes these materials are used for filling geotubes which may be used to bund a reclamation area. 

There are many ways to construct bunds. A distinction can be made between bund construction below water level and above water level. 

Bunds that will be raised in one lift from below water level to above water level can be constructed by  

Bunds built below water level (offshore) in various lifts will require water-borne 

To protect the bund from erosion during hydraulic filling, plastic sheeting is occasionally placed on the inner slope of the bund.
