Drainage Technology Explained: Jetting, CCTV and Relining
The days of solving every drainage problem by digging up gardens and driveways are largely over. Today, a suite of advanced, trenchless technologies enables us to accurately diagnose issues and implement lasting repairs with minimal disruption to your property.
Quick answer
Modern drainage technology, including CCTV surveys, high-pressure jetting, and CIPP pipe relining, allows us to diagnose and fix drainage issues from within the pipe, avoiding disruptive and costly excavation wherever possible.
This guide explains the core technologies we use—CCTV drain surveys, high-pressure water jetting, and Cured-In-Place Pipe (CIPP) relining. These methods form the backbone of our no-dig approach, prioritising the preservation of your landscaping, hardstanding, and peace of mind.
The Diagnostic Foundation: CCTV Drain Surveys
Before any work begins, we must see the problem. A CCTV (Closed-Circuit Television) drain survey is our non-invasive diagnostic tool. Our engineers deploy a flexible, high-resolution camera into the drain, providing a real-time, internal view of the pipe's condition directly to a monitor above ground.
This precise inspection allows us to identify the exact nature, location, and severity of issues—be it a blockage, a crack, root intrusion, or a collapsed section—without any guesswork. The recorded footage provides a permanent record, forming the evidence-based plan for any necessary repair, ensuring we use the most targeted and property-preserving method.
High-Pressure Water Jetting: The No-Dig Clearance
For stubborn blockages caused by grease, scale, silt, or roots, high-pressure water jetting is our primary trenchless clearance method. This technology uses a specialised hose and nozzle that blasts water at extremely high pressure through the pipe.
The combination of pressure and directional nozzles effectively cuts through debris and scours the pipe walls clean, restoring full flow. It's a highly effective alternative to mechanical rodding and avoids the risk of damaging pipes that older methods can cause. For persistent root ingress, jetting can clear the immediate blockage, after which a relining solution can be recommended to prevent recurrence.
CIPP Relining: The Trenchless Pipe Repair
When a pipe is damaged but not fully collapsed, Cured-In-Place Pipe (CIPP) relining is our flagship no-dig repair solution. This process involves inserting a resin-saturated, flexible liner into the existing damaged pipe through an existing access point.
The liner is then inflated against the host pipe's inner wall and cured using hot water or UV light, forming a jointless, durable 'pipe-within-a-pipe'. This new structural lining seals cracks, bridges gaps, and prevents root intrusion, typically with a lifespan of 50 years or more. It completely avoids the excavation, reinstatement, and landscape destruction associated with traditional pipe replacement.
- Solves issues like cracks, fractures, root damage, and joint failure.
- Can be installed through bends and changes in diameter.
- Creates a smooth, corrosion-resistant interior that often improves flow.
- Completed typically within a day, with immediate use restored.
The Technology Workflow: From Diagnosis to Cure
These technologies are most powerful when used in a logical sequence. A CCTV survey is always the critical first step, providing the diagnosis. If a simple blockage is found, high-pressure jetting provides the cure.
If the survey reveals structural damage, we move directly to a trenchless repair plan, most commonly CIPP relining. This integrated workflow ensures every action is justified and precise, eliminating unnecessary excavation. Our goal is to preserve your property's integrity by fixing the problem from the inside, not the outside.
Why Choose a Trenchless Technology Approach?
Choosing a drainage specialist who prioritises these technologies means choosing property preservation. The benefits extend far beyond simply fixing a drain.
Excavation is not only disruptive but can damage tree roots, garden features, patios, and driveways, leading to costly and time-consuming reinstatement work. Our no-dig methods bypass all of this. They are faster, cleaner, and often more cost-effective when you consider the total project impact. They represent a precise, modern solution that respects your home and your time.
- Minimal Disruption: No large trenches, no landscape destruction.
- Property Preservation: Protects driveways, landscaping, and structures.
- Speed: Most relining projects are completed in a single day.
- Longevity: CIPP liners provide a durable, long-term solution.
- Cost-Effectiveness: Often lower total cost when reinstatement is factored in.
Fixed price before we travel
Every visit is priced as a clear fixed fee — not an open-ended hourly meter that climbs while someone guesses.
CCTV-confirmed, not assumed
A camera check confirms the drain is genuinely clear or the defect is genuinely diagnosed, not just assumed from flow.
Documentation that holds up
Footage, defect codes and a written report when a managing agent, surveyor or insurer needs more than a one-line invoice.

Frequently asked questions
Is pipe relining as strong as replacing a pipe?
Yes, in most cases. The cured-in-place pipe (CIPP) liner forms a jointless, structural pipe within your existing one. It is highly durable, resistant to corrosion and root intrusion, and typically has a design lifespan exceeding 50 years. It is a permanent repair, not a temporary patch.
Will high-pressure jetting damage my old pipes?
When performed by our trained engineers, jetting is safe for most pipe materials. We select the appropriate pressure and nozzle for your specific pipe type and condition. The technology is designed to clear blockages without causing harm, unlike mechanical rodding which can sometimes crack or disconnect fragile pipes.
Can every drainage problem be fixed without digging?
While our goal is to use trenchless methods wherever possible, a completely collapsed pipe that has lost its shape may require a small, targeted excavation. However, a CCTV survey will confirm this. The vast majority of issues—blockages, cracks, root ingress, and fractures—are perfectly suited to no-dig solutions like jetting and relining.
How long does the CIPP relining process take?
One of the key advantages is speed. Most standard domestic relining projects are completed within a single day. The resin curing process takes a few hours, after which the pipe is immediately ready for use. This is significantly faster than the multi-day process of excavation, replacement, and reinstatement.
Do I need a CCTV survey if I already know where the blockage is?
We strongly recommend it. What feels like a simple blockage could be a symptom of underlying structural damage. The survey provides definitive evidence, ensuring we apply the correct solution first. Attempting to jet a damaged pipe without knowing could be ineffective. The survey saves time and cost in the long run by guiding the most effective repair strategy.
