Always read the installation instructions supplied with your order carefully before starting any installation work, as they may vary depending on configuration and selected options.
Installation should be carried out by qualified personnel and adapted to the specific conditions of the project.
Always follow the specific operation and maintenance instructions supplied with your order, as requirements may vary depending on model, material, and selected options.
To ensure reliable long-term performance, the drainage channel should be maintained regularly. Insufficient maintenance can lead to reduced water flow or, in worst cases, blockages in the system. Particular attention should be given during periods with high levels of sand and debris, such as after the winter season.
What is a drainage system?
A drainage system is designed to remove rainwater and surface water from hard surfaces such as roads, parking areas, courtyards, and industrial sites. Its purpose is to prevent flooding, reduce wear, and create safe, durable environments.
What is a channel drain or linear drainage?
A channel drain, also known as linear drainage, is a long, narrow system that collects and directs water along a surface. It is used where large volumes of water need to be managed efficiently, such as at airports, roads, and public spaces.
What is a slot drain?
A slot drain is a type of channel drain with a narrow slot opening instead of a traditional grate. It provides a discreet appearance, reduces the risk of damage, and requires less maintenance while still handling high water flow.
When should you choose linear drainage instead of point drains?
Linear drainage is ideal when water needs to be collected along a continuous length, such as on large surfaces or where slope is limited. Point drains are better suited for smaller, localized areas.
Which load class should I choose?
The required load class depends on traffic and usage:
- A15 – pedestrian and cycling areas
- B125/C250 – parking areas and light traffic
- D400 and above – roads and heavy traffic
- F900 – airports and extremely heavy-duty applications
Where are drainage channels used?
Drainage systems are used in a wide range of environments, including:
- Airports and military facilities
- Ports and terminal areas
- Roads and heavy traffic areas
- Parking areas and logistics sites
- Courtyards, public squares, and pedestrian zones
What materials are best for drainage channels?
Common materials include galvanized steel and cast iron, offering high strength, long service life, and corrosion resistance. The choice depends on load requirements, environment, and lifespan expectations.
Do drainage channels require maintenance?
Yes, regular maintenance is essential to ensure proper water flow. Channels should be inspected at least once a year and cleaned of sand, leaves, and debris—especially after winter.
How do you clean a drainage system?
Drainage systems are typically cleaned by high-pressure flushing via access points and by manually removing debris from the slot. Sumps and catch basins should be emptied when needed.
What is a catch basin and why is it needed?
A catch basin collects sand, gravel, and debris before it enters the drainage system. This helps prevent blockages and extends the lifespan of the system.
How often should drainage systems be inspected?
At least once a year, but more frequently in demanding environments such as industrial areas, ports, or locations with high levels of debris.
Can drainage channels be customized?
Yes, systems can be adapted with different widths, lengths, slot openings, and connections depending on flow requirements, load class, and surface finish.
What are the benefits of slot drains without grates?
Slot drains have no loose components, which reduces maintenance, noise, and the risk of damage or theft. They also provide a more discreet and integrated appearance.
How do you size a drainage system?
Sizing depends on rainfall intensity, surface area, slope, and flow requirements. Larger projects often require hydraulic calculations to ensure sufficient capacity.
Can drainage systems be used in cold climates?
Yes, drainage systems can be designed for cold climates and may include heating cables to prevent ice formation and ensure reliable performance year-round.
