CULVERTS

Precast Culverts play a vital role in water management by directing the flow of water under infrastructure like roads and railways. They are commonly used to manage stormwater, drainage, floods, and tidal movements. These culverts ensure that water can pass through developed areas without causing damage or disrupting natural flow patterns.
Unlike Pipes, Precast Culverts are usually box-shaped or elliptical rather than circular. This shape allows them to handle larger volumes of water, especially in shallow or wide areas where pipes would be less effective. Culverts are also generally easier to inspect and maintain because of their size and accessibility. While Pipes are more suitable for pressurized systems or small-scale drainage, Culverts offer greater strength and flow capacity for larger projects.
To deal with erosion, Culverts are often paired with features like Wing Walls and Headwalls, which stabilize the soil and guide water smoothly through the structure. Energy Dissipators and Aprons may be added to slow down water exiting a Culvert, preventing it from eroding the downstream area. Materials like Riprap or Geotextiles are used around the Culverts to reinforce the surrounding ground and reduce erosion.
In coastal areas, Culverts are designed to manage the challenges of Tidal Waters. They are made with Corrosion-Resistant Concrete to withstand Saltwater Exposure. Their design may include extra capacity to handle both Tidal Inflow and Stormwater Runoff during heavy rains.
