We will guide you through every step of installing channel drain products, whether you’re looking for information on how to install a channel drain in a driveway, how to install a channel drive in concrete, or even how to install a channel drain in front of a garage.
Pavement channel drain installation
When installing channels into block paving, you should install them at the lowest point of the problem area so that rainwater will drain into the channel drain because of the area’s slope.
Install channels into a driveway to drain water
Driveways are often susceptible to water damage during the rainy season, which can be a major cause of concern for homeowners. One way to solve this issue is to install channels into the driveway to drain water. The process involves cutting channels into the driveway and creating a slope allowing water to flow to the drainage system.
Installing channels into the driveway has many benefits, including preventing water damage and ensuring that water does not collect in low areas, which can be a breeding ground for mosquitoes and other pests.
To install channels into a driveway, you will need to follow these steps:
- Plan the location of the channels: Determine where you want to install the channels and mark the area.
- Prepare the driveway surface: Remove any debris or materials from the driveway surface to ensure the channels will be installed on a clean and level surface.
- Cut the channels: Cut channels into the driveway surface using a saw.
- Create a slope: Use a trowel to create a slope allowing water to flow towards the drainage system.
- Install the channels: Install the channels into the cuts and secure them with adhesive.
- Test the drainage: Once the channels are installed, test the drainage system to ensure water flows properly.
In the case of sloped driveways that lead onto main roads, channel drains are especially helpful. Overflowing rainwater will naturally be directed to the ditch before reaching the road on this slope. By following these steps, you can ensure that your driveway is properly protected from water damage and that you can enjoy a dry and safe driveway. The channel drain system prevents runoff from flooding the road so that any run-off from your property is channeled into a drainage system.
Channel drains
A channel drain can also be called a trench drain, linear channel, or drainage channel because they manage surface water efficiently, especially on non-porous surfaces. This prevents ponding, and even heavy downpours are effectively handled.
To prevent debris from blocking channel drains, channel drains are generally shaped like troughs and covered with grates. There are many locations where channel drains are used, such as garage thresholds, patios, driveways, airports, swimming pools, and garages.
Channel drains come in different types
A channel drain is made from several different materials, each of which offers different benefits.
1. The most common are plastic drains
Polypropylene, lightweight and durable material for channel drains, is a popular choice. It is ideal for gardens, driveways, and landscaping projects as it makes transportation and installation easy. ACO, Flexseal, Haughton, and others offer plastic channel drains.
2. Drainage channels made of concrete
Concrete channel drains are more chemically resistant and offer greater strength. As an alternative to concrete, ACO developed Venite’s material, which is lightweight yet strong and chemically resistant. Fiber-reinforced concrete from Hauraton allows the product to be more stable without thick walls to reduce the overall weight.
3. Drain gratings for channels
There is also a wide variety of channel drain grating materials available, such as cast iron gratings, steel gratins, galvanized steel gratings, and even plastic gratings.
The weight classes of channel drains
When choosing the right drain for your project, a channel drain’s weight load class must be considered. It is essential to decide which channel drainage is appropriate for the area you plan to install it. There are various weight classes to choose from.
1. The most common class is A15
Among the most common channel drain products available are those rated as Class A15. Channel drainage products that are Class A15 rated can withstand a maximum of 1.5 tons of weight and are intended for pedestrian traffic only. For small landscaping projects such as gardens and patios, use Class A15 channel drainage.
2. Channel drainage class B125
Approximately 12.5 tonnes of weight can be accommodated by B125 channel drains. In domestic driveways, patios, and thresholds, B125 is most commonly used.
3. The C250 channel drain is also commonly used
Drains classified as C250 can withstand weight loads of up to 25 tonnes. For small private parking lots, roads with light traffic, and other areas, these channel drains are suitable, but not for areas with frequent Lorries.
4. A class D400 channel drain is available
Drainages fitted with D400 channel drains are often referred to as highway drains because of their exceptional strength. D400 channel drains are ideal for main streets, highways, and public car parks.
5. Type E600
Channel drains with the E600 classification can withstand up to 60 tons of weight. E600 channel drains are generally installed in reinforced concrete in factories, loading bays, and warehouses.
6. There are also F900 channel drains
This category encompasses the most robust drainage channels. They are most frequently used in areas subjected to specific heavy machinery and transportation, such as airports, docks, and other industrial fields where huge weights and pressures are encountered. Class F900 channel drains can support a maximum weight of 90 tones.
Can gravel be used to install a channel drain?
How can gravel driveway issues be resolved? Gravel driveways don’t need channel drains, unlike concrete driveways. Instead, the problem can be solved by installing a twin-wall or land drain beneath the gravel in a French drain system, which will divert the water to an appropriate exit.
Installing a channel drain
Planning and preparation
Install the channel drainage where it will discharge into the main drainage, while channel drains are usually discharged into the main drainage via a pipe union end cap or bottom outlet sections, some channel drainage products come with pop-outs that can attach to a regular drainage pipe.
Dig a trench.
Digging a trench in the ground is the first step. If the channel drain fits neatly into the trench, it should reach the surface, 2mm below the surrounding flooring, but with an additional 100mm to allow the concrete to be placed below the trench.
Assembly of drainage channels
The length of the channel drainage should match the length of the preformed outlet, and any other components such as a silt trap should be in place for installation. Once the drainage channels are assembled, ensure all the end caps are installed.

Cover the drainage channels with concrete
Concrete should be placed in the trench bottom 100mm thick – but compacted fill can be used if the channel drain is only for pedestrian traffic.
Create drainage channels
Ensure the drainage outlet is connected to the drainpipe, and lower the drainage system into the prepared trench. Then, you can add backfill or concrete around the channel run before pressing a mallet into the trench.
