Indramayu-Cirebon, West Java/Indonesia
Secutex® R 601 Secugrid® 40/40 Q6
The project ‘Muara Karangsong’ was developed under the Department of Waterway Engineering, Ministry of Public Works, West Java, Indonesia. The previoud design included stones and gabions. As there was a restricted budget stones would have had to be delivered from other areas by using a plenty of trucks, which would cause damages for the current access road.
The choosen system combines the old with Softrock® containers (15,200 pieces). These containers (each with a size of 0.6 m³) were filled with existing soil which is a cost saving solution. The designers also changed the specification of the reinforcement: Secugrid® 40/40 Q6, a high quality geogrid made from interlaced extruded polymer bars with high strength monolithic welded junctions, from NAUE was used instead of a traditional bamboo mattress.
The following system solution was applied: pilling system with wooden piles; reinforcement with Secugrid®; 40/40 Q6; softrock® 601 containers, used as a core of the jetty; stone gabion for cover and protection; sand cover; concrete pre-cast for the access road.
The innovative solution contains various advantages, e.g. a; quick; easy and cost saving installation in half of the time; which shows that a solution using NAUE material can replace conventional designs.
