Elastogran GmbH, a Lemförde, Germany-based subsidiary of BASF Group, has begun commercial sales in Europe of Elastocoast, a system for reinforcing broken rock revetments with a polyurethane binder. Pilot installations to protect several quickly disappearing North Sea German Islands, including Hallig Gröde (shown here) armored in two projects in 2006 and 2007, have performed well. The binder is tumbled in a concrete mixer on-site and spread over a substrate. A Wyandotte, Mich., U.S. branch is working with the U.S. Army Corps of Engineers to develop design guidelines for U.S. use.
