CrocGuard® Bridge & Culvert Barrier

CrocGuard® is a revolutionary bridge & culvert barrier spanning up to 16m between abutment posts. Featuring a unique composite design comprising external thrie-beam rails that encases a concrete core, the system transfers impact loads to the posts at each abutment.

CrocGuard® applications include weak bridge decks that have insufficient structural capacity to withstand vehicle impact loads from a conventional post and rail barrier or culverts where there is insufficient fill height to support posts or a strip footing.
