Drainage is a complex and often underestimated subject. In addition to drainage, drainage channels make an important contribution to safety and material protection.

There are suitable channels for all requirements and conditions. For the product comparison, we have selected some models for you and compared them with each other. We will also answer the most important questions about drainage channels.


  • The drainage gutter is a device that removes water from surfaces and can thus reduce various hazards, such as aquaplaning.
  • Such gutters are available in different materials, load capacities and sizes, so you can find the perfect product for your purposes.
  • A drainage gutter can be installed by a professional contractor or even by yourself.

The Best Drainage Channel: Our Picks

Buying and evaluation criteria for drainage channels

In order to find the perfect drainage channel, we have worked out some buying criteria that you should consider when buying. These criteria make it easier to compare individual models so that you can make an objective and informed choice.

The criteria by which you can compare drainage channels are as follows:


Concrete, plastic or polymer concrete? A drainage channel consists in detail of a cover in the form of a steel grating and the channel underneath. The material plays a major role. The primary factor here is the load to which the channel is to be subjected.

Depending on where the gutter is to be used, some materials are more suitable. A pure concrete channel, for example, is suitable for very high loads, but has less tensile stress than a polymer channel and often has to be supported by surrounding soil. Consideration should also be given to whether, for example, chemicals are likely to be present in the wastewater.

Type of water drainage

If the water comes, it must be removed. But how? At this point it is important to note whether there is already a natural slope at the construction site. Then the decision can be made between a gutter with a slope or without a slope.


Cleaning the gutters should be carried out conscientiously and regularly, as otherwise blockages due to leaves and dirt can occur. This is especially important in autumn and spring. Cleaning can vary from gutter to gutter in terms of time and difficulty.

You should consider beforehand how much work and time you can and want to invest in cleaning. For example, gutters with grates require a grate hook to open them. Some gutters even have leaf traps that make cleaning easier by means of a box that can be easily removed and emptied.


Depending on the amount of water that needs to be drained, there are different types of drainage channels that can suit your needs. The design and cleaning can also play a major role, especially on your own property.

Drainage channels are available in three types: box channels, slot channels and open channels. Box gutters, for example, are capable of carrying much more water than slot gutters, which are, however, more often perceived as more modern and discreet. Open gutters, on the other hand, are the easiest to handle during service work.

Frequently asked questions about drainage channels answered in detail

In the following, we would like to answer the most frequently asked questions about drainage channels to give you a deeper insight into the topic.

What is a drainage channel?

A drainage channel is a linear drainage device designed to remove rainwater from larger surfaces. The excess water is led to the gutter through a slope and from there it is directed to infiltration or to the sewage system. The gutters are produced in various nominal widths (inside clear dimension).

Where is a drainage channel necessary?

Drainage channels are necessary in all places where rainwater can accumulate or collect. This includes, among other things, car parks, runways, driveways, terraces or streets. The areas of application are countless.

The gutters provide water drainage and reduce hazards from standing water, which on motorways, for example, lead to so-called aquaplaning. In some municipalities, there is a law that water that collects on private car parks has to seep into private property. A drainage system is also necessary there.

What kind of stresses can drainage channels be exposed to?

Since drainage channels are often located on surfaces with traffic, the question often arises as to what loads the channels can easily bear. In order to easily classify these load-bearing capacities, there are certain DIN regulations.

Load class Area of application
A15 Surfaces that are only walked on
B125 Parking areas, garages
C250 Verges and kerbs
D400 Roadways of roads
E600 Industrial and military areas
F900 Taxiway areas of airports

It turns out that you can use the DIN regulations to find the right channel for your requirements and area of application. You should pay attention to this so that the channel can withstand the loads. In the private sector, a load class of up to C250 should be completely sufficient.

What costs should I expect?

Of course, how high the costs are depends on whether you tend to do the installation yourself or hire a specialist company to do it for you. The costs for the company are in addition to the material costs per metre and vary between 20 and 70 euros per metre depending on the soil conditions and trench depth.

The cost of the gutter varies greatly depending on the material, height and width. You should also consider the costs for a drainage pipe and the connection to the sewage system. Overall, you should expect average costs of 550 to 800 euros if you have 6 metres of gutter laid by a specialist company.


Drainage systems are an important aspect for private and public areas. Drainage channels are a very good and simple solution for removing rainwater. You should pay attention to the purposes for which they are to be used and which materials, types of gutters and slopes are best suited for this.

You should also consider in advance what level of service the gutters require. As you have seen, there is the right model for every need, be it appearance or high load capacity.

Drainage channels can be used almost anywhere once the right channel has been selected. Even when chemicals are involved, the drainage channel is the perfect partner. It is a real all-round talent!
