Pebble and rock river bed for garden drainage
Many gardens have some sort of drainage issue; drain pipes that don't carry water away from the foundations, areas that become waterlogged during the rainy season, and a myriad of other reasons. It is important that excess water be drained or run off from a property as quickly as possible if you want to avoid damage to structures.
On an established property, correcting problems with water drainage and run off can be an expensive project. But there are alternative ways to sort out soggy gardens and water build up against walls.
During the rainy season hundreds of litres of storm water flows from the roof and down gutters to be dumped on your garden. A garden that does not naturally slope to allow water run off or where there is insufficient drainage, can result in excess water collection on a property that can ultimately lead to damage to foundations and structures.

A pebble river bed is one of the easiest methods of coping with excess storm water and also adds a new dimension to the garden. Very little work needs to be done to incorporate a pebble river bed other than planning the position and digging out a trench to fill with pebbles and rocks. Dig out a trench 25 to 30 centimetres deep, fill with gravel and top this off with pebbles and / or rocks.

You can buy assorted pebbles at your local Builders, garden centre or nursery, although for larger quantities you may want to consider a supplier that specialises in pebbles and rocks and can deliver these to the site. You may also find that this works out far cheaper than buying lots of small bags from the garden centre.

Using pebbles and rocks you can create a dry river bed that meanders through the garden. These features work well in an indigenous or water-wise garden design, as well as assisting with natural drainage for excess water.

If you live reasonably close to the coast you can save a lot of money by collecting pebbles from the beach and combining this with building gravel.
