Regardless of the culvert material (steel, concrete boxes) the flexibility of our solutions enables them to be successfully integrated into the project.The culvert may also be part of a number of hydraulic structures working together to ensure stability of the watercourse; weirs, cascades, channels.

Flow regimes through culverts can be complex. Care is required at the edges of the protection works where the channel returns to natural materials.The most effective solutions often combine products to optimise technical performance and cost.

When the riverbed is not well defined, or variable, it is good practice to extend the culvert wing walls to
protect the flanks
