Geotextile tubes
Geotextile tubes consist of a water permeable, sand-sealed geotextile filled with sand
or other granular materials. The tube diameter can vary from 0.5 m to 5.0 m and
the length may vary from 25 to 100 m depending on the project where the geotextile
tubes will be installed.
5.1 APPLICATIONS AND GENERAL
EXPERIMENTAL DATA
Geotextile tubes are often used in coastal areas, functioning as beach groynes, break-
waters, dune toe protection, submerged reefs, containment dykes (see Figure 5.1) or
core structures. They offer extra protection against flooding during heavy storms and
regulate sediment transport. For hydraulic structures, geotextile tubes can also serve to
temporarily replace rip-rap, especially in temporary works and locations where there is
a lack of stone. Where a structure is required to be permanent, the inner granular layers
can be replaced by geotextile tubes, with the outer armour stone remaining. Applications
