When is Drain Excavation Needed?

Drain excavation is sometimes the only way to resolve serious drainage problems.



We may recommend excavation if you have:

Misaligned or collapsed drain pipes

Damage at pipe joints or connections

Cracks or structural damage in the pipes

Issues where realignment or relining isn’t enough

How Our Excavation Process Works


Our drain excavation and groundwork services are carried out with precision and care, ensuring safety and compliance every step of the way:


  1. Diagnosis: After identifying issues through an inspection or a detailed CCTV drain survey, we determine the severity of the problem.
  2. Evaluation: If the issue cannot be resolved with a non-dig solution, we prepare for a professional excavation.
  3. Preparation: Our team, equipped with the necessary tools and extensive experience, plans the excavation. This ranges from minor domestic dig-ups to major commercial projects, addressing pipes of varying depths and sizes.
  4. Coordination: We work closely with the relevant authorities to ensure the excavation complies with all regulations and standards.
  5. Execution: Our skilled team carries out the excavation and repair work, aiming for a water-tight and durable solution.
  6. Completion: The goal is to install a functional, professionally executed drainage system designed to last many years, minimising future disruptions on public land.

Drain Repair & Relining Services

Not every drainage problem requires excavation. We offer a range of drain repair and maintenance solutions, including:


  • CCTV Drain Survey: Utilising the latest technology, our CCTV drain surveys are the first step in diagnosing the cause of the problem. This non-invasive method allows us to inspect your drain pipe thoroughly, identifying any issues without excavation.


  • Drain Relining: For pipes that are damaged but not beyond repair, drain relining offers a less intrusive solution. This method reinforces your existing pipes, sealing any cracks or holes, effectively restoring the integrity of your drainage system without the need for extensive excavation.


  • High-Pressure Water Jetting: One of the most effective ways to clear blockages and maintain your drains is through high-pressure water jetting. This process uses water at high velocity to remove debris, grease, and other obstructions, ensuring smooth flow within your drain pipes.



These methods can often save time and money while extending the lifespan of your drainage system.
