Root Ingress in Drainage Pipes – Causes, Signs & Solutions

Root ingress is a common drainage issue that affects many homes and businesses, particularly those with older drainage systems. It occurs when tree or plant roots penetrate underground pipes through small cracks, joints, or damaged sections. Over time, the roots grow inside the pipe, feeding on moisture and nutrients. As a result, this can cause severe blockages, water backups, and structural damage to your drainage system.

What Causes Root Ingress in Drains?

In most cases, older pipes made of clay or concrete are more vulnerable to damage. Even small gaps in joints can release vapour, which eventually attracts nearby roots. Once inside, the roots continue to grow, gradually restricting water flow. Consequently, the pressure may break pipe walls or cause complete collapse.

Warning Signs to Watch For

• Toilets, sinks, or showers draining slowly

• Gurgling or bubbling noises from plugholes

• Foul odours coming from drains

• Frequent blockages or overflowing drains

• Soggy patches or sinkholes in your garden

If left untreated, root ingress can lead to extensive damage, including flooding, pipe collapse, or even property subsidence.

How We Fix Root Ingress

At Drain Maintain, we start with a detailed CCTV drain survey to identify the problem. Once diagnosed, we can remove roots using methods like high-pressure jetting, mechanical cutting, or specialist tools. After clearing the blockage, we often recommend no-dig drain relining to seal the pipe and prevent future issues.

However, if the damage is extensive, we may advise excavation and pipe replacement.

Prevent Future Root Intrusion

To avoid future problems, regular drain inspections are highly recommended—especially if you live near trees or large shrubs. By acting early, you can prevent expensive repairs and long-term disruption.
