Korean coastal community fights erosion with BASF solution
Seoul, South Korea – November 19, 2015 – Revetments made with BASF’s innovative solution for coastal protection, Elastocoast®, now cover the shoreline of Goseong, Geoje Island in South Korea. The solution helps manage sediment and provides protection against coastal erosion during typhoon season.
Instead of paving the coastline with concrete or tar, the Elastocoast polyurethane binder bonds rocks and aggregate into a stable yet porous structure that absorbs wave energy. This prevents damage to the revetments and reduces wave run-up.
“Our first application of Elastocoast was in 2004, over the shoreline of Hamburger Hallig in Germany. Since then, we have continued to demonstrate the high mechanical strength and long-lasting stability of Elastocoast in various projects globally,” said Andy Postlethwaite, Senior Vice President Performance Materials Asia Pacific, BASF. “In Asia, revetments made with Elastocoast will be beneficial to protecting the coastal infrastructure across countries such as Korea, China, Japan and ASEAN, which are affected by heavy storms and typhoons each year.”
Elastocoast is a proven solution for coastal protection in Korea
In South Korea, Elastocoast has already been used along the shorelines of the Jeonnam area. Korea’s first revetment built with Elastocoast, installed in 2011, has remained intact even after weathering 12 typhoons.
The Goseong project at Geoje Island is the seventh joint project by BASF and SBB using Elastocoast. As a manufacturer of concrete blocks for river and coast protection, SBB is working with BASF since 2010 using Elastocoast as a versatile solution to safeguard shores from strong winds and erosion: The Goseong project was completed just before the beginning of the typhoon season.
“In our search for technical alternatives that also deliver economic and environmental benefits, we chose Elastocoast for its permeability. It is also easy to work with and to install using conventional construction equipment,” said Mr Lee TaeHyoung, President, SBB.
SBB chose Elastocoast for its high permeability and porosity, but also because it supports the ecological balance and the native biological environment of the coastline. Biological studies by the University of Amsterdam have shown that revetments made with Elastocoast are colonized by the flora and fauna typical of the local region within just a few weeks. The findings demonstrate sustainable repopulation of the surface by maritime organisms and proves that Elastocoast can also be used in sensitive environments like National Parks.
Coastal protection against rising sea levels and undercurrents
According to the International Panel on Climate Change, about 12 million people in 23 coastal cities across China, Japan, and Korea make up 28 percent of the total global population living in low-elevation coastal zones. Such cities are at risk of severe flooding from rising sea levels.
Revetments made with Elastocoast provide coastal protection against the effects of rising sea levels and undercurrents. When extended below water level, the revetment protects the coast against undercurrents that can lead to an erosion of the shoreline beneath it. Even with rising sea levels, waves are prevented from running up and causing floods as the wave energy is absorbed by Elastocoast.
