If you're looking to stop standing water on large paved areas like driveways, parking lots, or patios, channel drains (also known as linear or drainage channels) are a great option. These drains connect to an underground drainage system and are often necessary for driveways larger than 5 square meters. They are cost-effective and relatively easy to install.
However, proper installation is key. If not done correctly, you might not achieve the desired outcome, and there's a risk of simply shifting the water problem elsewhere. To help you, we've put together a detailed guide covering:
- What channel drains are and common uses.
- The different components involved in installation.
- A step-by-step 11-point guide for installation.
- Essential dos and don'ts.
**Key Takeaways:**
- A channel drain is essentially a long drain with a grate on one side to let water in and direct it away.
- It should be connected to an underground drainage system via an outlet.
- Always follow the guide for proper installation.
- Choose the appropriate load rating based on the area and traffic it will handle.
Channel drains are versatile and can be found everywhere from small domestic spaces to large industrial sites. They are low-profile and efficient, moving significant amounts of water due to their elongated shape and cross-sectional design.
Common materials include black plastic or composite options, with grates made from PVC, composite, or sometimes stainless steel. Domestic drains typically handle up to 5 tons of weight, while commercial ones can manage much more, suitable for heavy traffic areas like airports or loading zones.
Connecting channel drains to an underground system can be done in two main ways. You can use one of the three outlets provided, cutting them to fit 110mm drainage pipes. Alternatively, end outlets can be used if the main drainage system is located at the ends of the channel drain.
Channel drains are used in a variety of settings, from driveways and patios to industrial areas and even swimming pools. Their load-bearing capacity varies, making them suitable for everything from pedestrian walkways to heavy vehicle traffic zones.
The typical components of a channel drain installation include:
- **Drainage channel sections:** Main parts of the installation, usually 1-meter sections with slotted ends for easy connection.
- **End outlets:** Allow connection to the main drainage system at the end.
- **Grating:** Made from various materials, it sits flush with the surface, providing safety and access.
- **End caps:** Seal the highest points of the installation.
- **Quad sections:** Connect multiple sections at 90-degree angles.
- **Sump units:** Optional but useful for preventing blockages and odors.
Each component is usually purchased separately, though some brands offer kits, like Clark Drain's garage packs.
**Installation Guide:**
1. Dig a trench deep enough for at least 50mm of compacted sand and wide enough for 100mm of backfill concrete on either side.
2. Attach a string line to indicate the final grate height, 2mm below the surrounding surface.
3. Plan a 1:200 fall—5mm drop for every meter of channel.
4. Start installation at the lowest point, using complete sections first and cutting any excess at the highest point.
5. Use the connecting slots to lock sections together and ensure the grate is in place for accurate height alignment.
6. Fit an end cap to the final section before placing it in the trench.
7. Seal the locating grooves with silicone sealant for better durability.
8. Attach the section to the 110mm underground drainage system.
9. Protect the grated sections with heavy-duty tape before pouring concrete.
10. Pour concrete to create a 2mm height difference above the grate.
11. Allow the concrete to cure for at least 72 hours before applying any pressure.
**Dos and Don'ts:**
- Start installation at the point where the channel meets the drainage system.
- Ensure proper drainage to avoid water accumulation elsewhere.
- Properly mask grates to prevent concrete overflow.
- Avoid directing water toward neighboring properties.
- Never connect to foul drains without permission.
- Stick to the load rating of your system.
Choosing the right products is crucial. Look for quality materials and those compliant with BS-EN1433 standards. Understanding load ratings is essential. For example:
- **A15 (1.5-ton load):** Ideal for pedestrian-only areas.
- **B125 (28-ton load):** Suitable for car parks and driveways.
- **C250 (56-ton load):** Good for light commercial areas.
- **D400 (89-ton load):** Used for high-traffic roads and commercial zones.
- **E600 (134-ton load):** Handles heavy-duty forklifts and similar equipment.
- **F900 (202-ton load):** Strong enough for aircraft runways.
