GRP Ballast Board

GRP Ballast Boards are a glass-fibre reinforced polyester (GRP) ballast board that offers reduced weight for easier installation, while retaining the strength to remain undamaged during transport and to resist damage when under load. GRP Ballast Boards are suitable for a multitude of uses, such as retaining ballast and protecting railway tracks and trackside facilities on embankments from rockfall and snowslide. The interlocking boards slot into steel or composite posts to form a barrier. They are fabricated from isophthalic polyester pultruded profiles, whilst vinyl ester is the resin system used to resist the corrosive attack to the posts due to the alkaline nature of concrete. Both resin systems are fire retardant, and contain UV inhibitors, whilst the outer surface of the profiles are encapsulated within a polyester surface veil, ensuring excellent weatherability, and no long-term drop-off in strength.
