CrocGuard®
Composite Thrie-Beam Barrier Spanning up to 16m
CrocGuard® Bridge & Culvert Barrier
MASH TL4 Compliant 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.
- MASH TL4 Compliant.
- Spanning up to 16m without posts.
- Outstanding durability and resistances to damage from vehicle impacts.
- Eliminates the often-destructive hydraulic load applied to bridges and culverts from conventional post and rail barriers during overtopping from flood waters.
