How Tree Roots Damage Drains

Tree roots are one of the most destructive forces affecting underground drainage in the UK. Roots naturally grow towards sources of moisture and nutrients — and your drain pipes provide both. Understanding how roots find and damage drains helps you take preventative action and choose the right repair method when damage has occurred.

What to Look For

• Roots grow towards moisture — drain pipes are natural targets
• Entry points are joints, cracks, and connection points
• Once inside, roots expand rapidly in the nutrient-rich environment
• Root balls trap debris, creating blockages
• Expanding roots crack and fracture pipe walls from inside
• Eventually, root pressure can cause complete pipe collapse

How We Diagnose the Problem

CCTV surveys clearly show root ingress — from fine hair roots at pipe joints to massive root balls filling the entire pipe bore. We identify the entry points and assess whether roots have caused structural damage beyond just blocking the pipe.

How We Fix It

We remove roots using mechanical cutting equipment and high-pressure jetting, then reline the pipe to seal all joints and cracks against future root entry. The seamless liner creates a root-proof barrier with no joints for roots to exploit.
