DREDGING PROFILE OUR SERVICES SHORELINE PROTECTION Rotawn constructs and maintains shore protection structures including jetties, groins, seawalls, breakwaters, and bulkheads in order to protect the coastline and the navigable water channels that can reach down to 100 meters. Early shore protection measures included jetties and groins constructed perpendicular to the shoreline for the purpose of lessening the impacts of erosion by reducing the rate of sediment transport along vulnerable coastlines. Rotawn has invested heavily in procurement of world class next generation marine equipment for secured shoreline protection. Our clients recognize our first class professional mode of operation & safety measures applied in ensuring that we don t end up causing erosion instead of protecting the shorelines.
