How to choose a drainage channel for your driveway
Many homeowners wonder whether they need a drainage system for their driveway or courtyard and how it should be designed to absorb large amounts of rainfall while being able to withstand heavy loads by vehicles passing over. In this article, we report on why a drainage system is essential and what there is to consider.
When do I need a drainage channel in the driveway?
It is important to ensure that no puddles of water form in driveways or front yards. This is not only paramount for your own safety but is also required by law. The reason behind it: rainfall should seep into the ground and not unnecessarily burden the sewer system. This is also regulated by law for reasons of flood protection. This is why a drainage system in driveways is obligatory in most municipalities. Depending on the county, it is also regulated whether rainwater seeping onto other properties or municipal surfaces such as sidewalks and roads must be prevented.
Choosing the right drain
For a small yard or parking area, drainage can already be achieved without a drain by installing a slope of 2 percent. However, this uncontrolled drainage is not always a good choice, for example, if the parking space is directly adjacent to a house.
For larger areas, the drainage of precipitation must be controlled. When it comes to choosing the right drainage channel for the driveway, some homeowners feel overwhelmed. Questions often arise when it comes to choosing a grate. The following tips should make your choice easier.
Drains designed for heavy-duty loads like cars
It is imperative to ensure that the drainage system you are installing in front of your garage can withstand the heavy load of a car passing over. This also applies to other areas that are used for driving or parking. Furthermore, it is important to ensure that the grates are slip-resistant. This helps to avoid accidents during heavy rainfall. A so-called linear drainage system is the optimal solution. It can be implemented in almost any area and can even be installed using the DIY method.
The right cover for your drain
The drainage system and the grate form a single unit. Both in terms of design and function. Since there is a wide range of combinations to choose from, you should clarify the requirements for the load-bearing capacity, design and material in advance and thus narrow down your selection.
Load classes according to DIN EN 1433
Grates are divided into different load classes, which provide information about the load the material can withstand. According to DIN EN 1433, drainage systems are divided into classes A15 to F900. Class D400, for example, can easily withstand heavy-duty loads such as traffic from lorries,
while class A15 is only suitable for cyclists and pedestrians.
Examples for grates used for private residences and residential buildings:
- Design grating CELTIC
- OvalGrip Design
- Longitudinal-bar grating
- Perforated grating
- Mesh grating
- Slotted grating and much more
The materials vary depending on taste and requirements. Common materials include steel, stainless steel, cast iron or plastic. The choice of
material depends on the loads the grate will later be exposed to. There are many available options to suit every taste. Grates made of uncoated cast iron and with detailed patterns are also becoming increasingly popular.
