FlexMac® W is used for similar applications to FlexMac DT, but in situations where there is a reduced risk of differential settlement.
FlexMac® W is a multicellular structure made of welded wire mesh. The mesh is internally lined with a non-woven geotextile sleeve.
The cellular structure is filled in-situ with locally available fill material to provide a barrier system against rising water, or to buttress excavations in temporary works.
FlexMac® W units are joined to each other longitudinally by using connecting pins to obtain the required length of the structure.
