Drainage and Ducts

The versatile box culvert can be used to channel water, enclose cables and, in larger sizes, as underpasses below bridges.

Designed to optimise water flow and route cables underground, the precast U-shaped drain is made with high-grade concrete for more durability.

With its sharp oval curve, the egg-shaped precast concrete drain ensures smooth water collection and conveyance underground.

A combination of a kerb and channel, the dual-purpose L-shaped kerb is designed to enhance pavement integrity and direct stormwater runoff.
