How To Install A Drain In Your Driveway

Installing an adequate drainage system on your driveway is not only a legal requirement but also a cost-effective solution to preserve the condition, appearance, and stability of your driveway. Driveway drainage channels collect surface water from your drive, channelling it into the main or underground drainage system. 

This article provides an in-depth guide on installing a drainage channel system in your driveway, along with the necessary tools to complete the job correctly. 

Does a Driveway Need a Drain?

Driveways are exposed to the elements, so if you have a perfectly flat drive, rain, snow, or even water from washing your car will sit and pool on the surface. This can cause long-term damage to your drive, not to mention an inconvenience to yourself. This is why a sloped drive and driveway drainage are essential.

Well-fitted driveway drainage channels help collect and move surface water away from your drive. They are usually positioned at the bottom of the drive, away from your property, and cover the entire width of the drive. Drainage channels can also be installed along the length of your driveway, depending on its slope. 

Can I Put a Drain in My Driveway?

Yes. All driveways should have appropriate drainage to ensure safety and longevity. Adding a drain to your driveway is a straightforward process. We have provided a step-by-step guide below; however, before you begin, it’s essential to have the necessary tiling tools to complete the task.

Installing a Drain in Your Driveway

1. Map out & prepare the area

Like most groundwork projects, you want to measure and mark out the area where you need to dig. This will ensure your drain channels are placed in the correct location, the first time. Figure out the slope of your drive and where surface water will collect. You also need to locate the main drain, as this is where your drainage channel will feed water into. 

Measure the length of your chosen type of drain channel and ensure you have enough channels to cover the length or width of your driveway. You can also pick up your drain end caps and drainage corners if needed. 

2. Dig your drainage channel trench 

Make sure you dig your drainage trench wide enough to fit your drainage channel and grate. If you’re wondering how deep to bury your drain channel, aim for 2mm below the ground’s surface. Add 150mm to the depth of the drainage channel to allow for a layer of sand (50mm) under your drainage system and a layer of concrete (100mm) that will sit around the system. 

3. Level the trench

For effective, long-lasting drainage, you want your drainage channel to sit on a flat, sturdy base. Once your trench is dug, pour a layer of sand (50mm) into the bottom and allow it to settle. 

4. Lay your drainage channel & grate

Lay your drainage channel on top of the sand and concrete base, and use a rubber mallet to gently tap it into place. If you have multiple drainage channels, ensure they are securely attached with drain connectors. To strengthen your drainage system, consider installing drain supports under the channel. Once placed, fit the end cap at the highest point and apply a sealant. Pour your concrete around the edges of your drainage pipe to keep it in place, and then add your drainage grate on top. 

5. Test Your Drainage Channels

Using a hose or bucket, pour water across your driveway and into your drainage channels. The water should run off the surface of your drive, into and along your channels, leaving no pools or standing water. 

The Different Types of Drainage Channels

There is a wide range of driveway drainage systems made from plastic, iron, stainless steel, or aluminium. There is no right or wrong when it comes to drainage channels, and it often comes down to personal preference and the desired finish.

Is Planning Permission Required for Driveway Drains?

By law, if your driveway exceeds 5m2, you must have adequate drainage to comply with building regulations. This helps reduce the threat of flooding in local areas, which can cause damage to roads, paths, and compromise people’s safety. If you’re adding a drainage to an existing driveway, you do not need planning permission. 

Planning permission is only required if your driveway:

• Is larger than 5m2

• Is made from a non-porous material 

• Is directing surface water into a road
