Here is a handy tool which will make suggestions based on some basic information about your garden drainage issue. We also include links to articles which will show you how to implement each type of drainage solution.

Make sure to read up on the regulations around redirecting surface water

Suggested solutions

Ground elevation

Elevating the ground is one of the cheapest and easiest drainage solutions for milder issues like yours. Use a sandy soil or porous base such as hardcore or gravel to raise the surface above the level of the water.

Drainage holes

The easiest solution for issues caused by waterproof surfaces. Its a good idea to install a surface drainage channel or holes which will allow the water to pass through the surface into the ground below.

Soil modification

Mild water logging issues in lawns are sometimes caused by clay soil which doesn't allow the water to drain. Rotivate/mix sand into the soil at a 50/50 ratio to break down the clay and improve the natural drainage of the soil. Alternatively use turfing soil which is around 70% sand.

Drainage ditches

A drainage ditch can create a natural area for water to drain into so that it doesn't sit where its not wanted.

Make sure you read our guide before digging a drainage ditch in your garden. We talk you through how to avoid the common mistakes.

Soak away crates

Soak away crates are installed under ground and create an area for water to drain into. They can be used to solve moderate and bad drainage issues but installation should be done with care to avoid errors.

French drains

French drains are used to redirect water through creating underground channels. The water can be directed to surface water drains, unused areas or soak away areas.

Pump drainage

For areas which have extremely bad drainage or where other solutions are not workable. Pump drainage can redirect large amounts of water but does require power and annual maintenance.
