Drainage channel for Driveways

When is a drainage channel for the driveway useful?

If the driveway is sealed, e.g. with a layer of asphalt or concrete slabs, the water cannot seep away and, depending on the gradient, can flow towards the house. Paved surfaces can allow some of the water to seep away through the spaces between them. In small areas, the water can be channelled down a slope into neighbouring areas, such as the lawn. However, these surfaces reach their capacity limits, especially during heavy rainfall. Drainage channels can be used effectively to prevent puddles of water or damage to the house.

Which drivable drainage channels are suitable for the driveway?

All drainage channels from load class B125 (loads of up to 12.5 tonnes) in accordance with EN 1433 are suitable for driveways and courtyards. From this class upwards, all channels can be used by cars. If the channel is not driven on and only walked on by pedestrians, then class A15 (loads up to 1.5 tonnes) is also sufficient. If the channels are labelled by the manufacturer as "accessible by car", then these are also sufficient for the driveway.

Example: Drainage of a driveway with drainage into a trough with a 2% slope. There is no general guideline for the slope and it depends on the type of surface or the expected amount of water.

Where should the rainwater from the driveway be channelled?

To protect the environment and the sewage system, water should seep into the ground on your own property. The local authority's regulations should be enquired about prior to installation. There are several ways to drain the water from the drainage channel. A connection to the underground pipe, a swale or even a soakaway can be the solution.
