Building Work Damaging Drains

Building work — from extensions and loft conversions to landscaping and driveway installations — is a common cause of drain damage. Heavy machinery, excavation near pipe runs, and increased load from new structures can crack, crush, or displace underground pipes.

What to Look For

• Drainage problems that appeared during or after building work
• New extension or structure built over drain runs
• Heavy machinery was used near known drain routes
• Piling or deep foundations installed near drains
• New paving or structures adding weight above drain pipes
• Builders accidentally broke into a drain during excavation

How We Diagnose the Problem

We use CCTV surveys to assess damage caused by building work, documenting all defects with footage and location data. This evidence is essential if you need to make a claim against a builder's insurance or your own policy.

How We Fix It

We repair building work damage using the most appropriate method — relining for cracked or displaced joints, excavation for crushed or collapsed sections. We also advise on drain protection measures for ongoing building projects to prevent further damage.
