Expert Drainage Services in the South East
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.
Sewer Connections
If you’re looking to create a new sewer connection to the main network, our qualified highway teams will ensure the project is carried out professionally and in accordance with the relevant Water Authority regulations.
