TenCate Geotube® Geobag for Riverbank Erosion Protection - Sungai Tenglu, Johor

Overview:
A meander of the Sungai Tenglu in Johor Malaysia was constantly subjected to significant fluctuations in water level during heavy monsoon rain. Progressive erosion of the riverbank along various sections of waterway had significantly weakened the embankment and threatened a massive collapse and loss of reserve land. The situation was such that Emergency repair works were deemed necessary to avoid further erosion during the pending monsoon season.

To solve this problem the Malaysian Dept. of Drainage & Irrigation (DID) evaluated various erosion protection methods before including traditional methods such as Gabions before finally settling on an option using large sand filled Geobags. The woven Geobags from TenCate were the preferred option due to their overall cost effectiveness and ease of filling and handling.
