The design of the reclamation dykes consisted of locally dredged silty sand fill contained between outer Geotube®containment units. Geotube® units were chosen for the outer protection for the reclamation dykes for a few reasons. Geotube® units have an efficient contact surface with soft foundation soils and do not suffer from local shear failures as do rock fill. The sizing of the Geotube® units had adequate mass-gravity to resist water forces caused by extreme typhoon storms. The Geotube® had to have a long term design life in exposed conditions. When expanding the reclamation area, it is not necessary to remove the Geotube® units as they can be just covered over with reclamation fill, and piled through during later development.
