Spillways / Cascades

Spillways / Cascades

An overflow spillway is most often constructed as part of a gravity dam or a buttress dam. The spillway section is lower than the other sections of the dam allowing water to flow over its top and down its front face.

FLI Carlow  have developed a precast concrete panel system to standardise the construction of the spillway channels and to provide a cost effective solution. We can construct spillway panels with form liner finishes where it is necessary to blend the structure with the local landscape.

Our DfMA solution is the most effective spillway solution available. Selected for value, durability, carbon, safety, and speed of construction our extraordinary portfolio of projects is only possible because our clients identified us as the best value.
