How to Improve the Drainage of Your Driveway

If when every time it rains you have long standing puddles on your driveway or water flowing into the road or towards your house, then it can be safely assumed that your driveway has not been designed with adequate drainage

Drainage problems on your driveway are not simply a matter of failure to comply with current legislations, they are unsightly, they result in muddy footprints on your floor and can even contribute to the wear of your driveway.

Current legislation in England states that rainwater needs to be absorbed into the ground near to where it falls. So, legally, you can’t simply channel the excess water into the road to end up in a public sewer. A reputable driveway installation company will be aware of the legislation, which may be specific to your local authority, and will be able to design your driveway without these drainage issues.

The solution they choose will depend on local legislation, the type of driveway you want and your budget

There are two ways of dealing with drainage:
Incorporating a gentle gradient and channeling water into a purpose built drainage channel.

The gradient chosen will be very small, about 1:80 from front to back, enough for water to drain but not enough to allow pushchairs and bikes to run away from you. Even if there is a grassy area nearby to act as a rainwater collection point, most reputable driveway companies will also install an ACO drive drain, which has been specifically engineered to collect rainwater from domestic driveways and patios.

Using a permeable driveway surface, such as gravel or specially engineered block paving materials.

The simplest type of permeable surface is gravel which, even in its simplest form, is naturally permeable. The more complex gravel driveways, such as Cedagravel still allow water to permeate through but have the added advantage of capturing potentially harmful pollutants within the geo-textile membrane.

The ACO drive drain collects surface water from your driveway and channels it into an underground drain. This water is then channelled into: a nearby ditch or watercourse, the main surface water sewer, or a soakaway. Your driveway company will need to install the appropriate feeder mechanism from the underground drain to whichever method of dispersal suits your area.

But you don’t have to settle for a gravel solution if your heart is set on block paving

Today’s technically advanced permeable paving means that you can have the choice of colours and styles of paving as you would with traditional systems. And as the issues surrounding non-permeable paving and the environmental hazards of excess water runoff are being more fully understood, more and more driveway products are being engineered to be fully permeable.
