Drainage Services – CCTV Drain Surveys, Repairs & Relining
CCTV Drain Surveys
A CCTV drain survey is the most accurate way to inspect underground drainage systems. Using advanced camera equipment, we can quickly locate blockages, assess pipe condition, and identify structural issues such as cracks, root ingress or collapsed sections.
We regularly perform:
- Homebuyer drain surveys – ideal when purchasing a new property
- Commercial drain investigations – ensuring compliance and preventing costly downtime
- Drain subsidence investigations – identifying potential structural risks
Our detailed survey reports include video footage, condition assessments and repair recommendations, giving you full visibility of your drainage network.
Drain Repairs & Pipe Relining
When damage is identified, Cascadia Water provides full drain repair services, including trenchless drain relining. Relining allows us to repair damaged sections without the need for extensive excavation, reducing mess, cost and disruption.
We also offer:
- Emergency drain repairs for collapsed or blocked drains
- Lining and patch repairs for isolated damage
- Full drain replacements when required
All work is completed by experienced engineers using proven techniques and high-quality materials to ensure a long-lasting solution.
Preventative Drainage Maintenance
We also deliver planned maintenance services, reducing the risk of blockages and ensuring systems run efficiently year-round. For businesses and facilities managers, we can create tailored programmes to meet your site-specific requirements, including regular cleaning and inspection schedules.
