How can you prevent tree roots from ingressing drainage pipes?

Tree roots will naturally seek out water and nutrients, which often makes your drainage pipes a target. Once roots enter the pipes, they can cause blockages, leaks, or even cause the pipes to collapse. Preventing tree roots from invading your drainage systems can save you from expensive repairs in the future. Here are our tips to protect your pipes from tree root ingress.

1. Plant Trees Away from Pipes

Before planting new trees, consider their potential root spread. Trees with large, aggressive root systems should be placed well away from any of your drainage pipes.

2. Use Root Barriers

Installing root barriers is a way to block roots from reaching your pipes. These barriers are usually made from strong plastic or metal and are buried between the trees and your plumbing. Root barriers force roots to grow in a different direction, keeping them away from your drainage system.

3. Regularly Inspect Pipes

Routine inspections of your drainage system can help detect early signs of root ingress.

4. Choose Quality Pipe Materials Modern pipe materials, such as PVC or ductile iron, are more resistant to root intrusion than older clay or concrete pipes. If you’re upgrading your drainage system, consider using these modern materials.
5. Apply Root Killers Chemical root killers are another option to consider to protect your pipes. These products are flushed down your drains and create a barrier that deters roots from growing near the pipes. Remember to use them carefully and follow the manufacturer’s instructions to avoid harming the environment or nearby plants.
6. Remove Problem Trees if Necessary If a tree is causing ongoing damage to your drainage system, it might need to be removed. This step is usually a last resort, but it can save you from recurring repairs in the future.
