Gabion and Reno Mattress® as a Seawall at Kampung Nelayan, Kenjeran 

Initially, the local government planned on using sheet piles or concrete structures to protect the coast from abrasion. However, the coastal area that needs protection is quite long thus a more affordable solution that still carries out its functions is needed.

The Sea Wall by Maccaferri consists of Gabion and Reno Mattress® is an alternative solution to protect the coast from abrasion and minimize the risk of structural failure caused by the tidal action. In the case of severe toe scouring due to the tidal process, the flexible structure of the Reno Mattress® will accommodate the sea wall deformation. 

Kampung Nelayan is one of the tourist destinations located in the city of Surabaya, East Java. In addition to its variety of seafood, Kampung Nelayan Kenjeran has an amazing view with a unique mix of colors from the residents’ homes. This is due to the local government that has made improvements for Kampung Nelayan Kenjeran since 2016 to attract more domestic and foreign tourists and boost the local economy. 

As part of the process, the local government also pays attention to the problem of abrasion because Kampung Nelayan is a coastal area. Initially, the local government planned on using sheet piles or concrete structures to protect the coast from abrasion. However, the coastal area that needs protection is quite long thus a solution that is more affordable and still carries out its functions is needed. 

Maccaferri Indonesia’s solution with the gabion sea wall was chosen as a better alternative solution to replace the original plan. Gabion sea wall consisting of Gabion and Reno Mattress® is installed with a length of 340 m. Gabions are installed with a height of 4 m with Reno Mattress as a foundation to protect the coast from abrasion and minimize the risk of structural failure due to the tidal process. In the case of severe toe scouring due to the tidal process, the flexible structure of Reno mattresses will accommodate the sea wall deformation. In addition, our non-woven geotextile MacTex® with separation function is also installed between the gabions and the backfill material to prevent the scouring of backfill material due to the tidal process. 

Maccaferri Indonesia provides comprehensive services starting from the design and planning stage with technical recommendations, manufacture and supply materials, and construction stage with Product Assistance. Most of the materials from Maccaferri Indonesia are manufactured locally in Indonesia under International and National Standardization and verified by TKDN certificate.
