Sheetpile profiles made from fibreglass are best for use in highly corrosive enviroment. Especially they can be used to protect the shore, to avoid errosion. The high corrosion resistance is best for use in seawater, the advantage over steel sheetpiles is dramatic. GRP-sheetpile profiles can be rammed into the ground if it contains not too much stones and rocks. Due to their low weight GRP-sheet piles can be used on difficult accessable areas and can be carried with hands to site.
