Drainage Outfalls – Concrete Drainage Channels

Concrete drainage channels (drainage outfalls) are one of the most important components of a drainage system. They connect the main drain to your drainage outlet, and so it is extremely important to choose the correct one for your project. By doing so, you will guard your main pipe against erosion and damage from the water pressure. Choosing the right outfall will also increase the efficiency of your drainage system. JKH Ltd can help you find an effective drainage unit appropriate for your project. We offer a wide range of concrete drainage headwalls and bespoke solutions to suit any budget.

Drainage Outfall Products

Constructing a cost-effective concrete drainage solution depends on many factors. Our design team can draw up a bespoke solution to ensure your outfall is suitable for your needs. You also have the option to use Glass Reinforced Cement (GRC) to provide a cost-effective, lightweight, and reinforced solution.

We have small and large general-purpose headwalls suitable for any size of pipe openings, that are lightweight with a unique anchorage system. A Kwikfit headwall is suitable for pipes up to 150mm, if you need larger than this then our GP headwall will fit up to 360mm OD pipes. Our Type X headwall is a one-piece concrete headwall that comes in three different widths.

Other Products

As well as bespoke solutions, we provide precast concrete drainage outfalls and many other products. These include sturdy gratings and steelwork. Our gratings are made from mild steel and hot-dip galvanized. They come with suitable brackets for mounting directly to the headwall structure. We also provide several types of silt traps to fit all sizes of pipes. Our selection of weirs and end walls offer further solutions. Choose from conventional and vee notch weirs to lagoon strainer or culvert end walls.
