Drain pipe relining, also known as cured-in-place pipe (CIPP) lining, is a non-invasive method of repairing damaged pipes without the need for excavation. This innovative technique involves inserting a new lining within the existing pipe, effectively creating a pipe within a pipe. The result is a seamless, corrosion-resistant pipe that restores functionality and extends the lifespan of your drainage system.
1. Cost-Effective
Traditional pipe repair methods often require extensive digging, which can be both time-
consuming and costly. Drain pipe relining eliminates the need for excavation, significantly
reducing labour and restoration costs. This makes it an attractive option for homeowners and
businesses looking to save money while still receiving high-quality repairs.
2. Minimal Disruption
One of the standout benefits of drain pipe relining is the minimal disruption it causes. Since
there’s no need to dig up floors, gardens, or driveways, the process is much less invasive.
This is particularly advantageous for commercial properties where extensive digging can
disrupt operations.
3. Durability and Longevity
The materials used in drain pipe relining are incredibly durable, often extending the life of
your pipes by several decades. The relining material is resistant to corrosion and root
intrusion, which are common issues that cause pipe deterioration. This means fewer repairs
and maintenance in the long run.
4. Eco-Friendly
By opting for drain pipe relining, you are also making an environmentally friendly choice.
Traditional methods involve disposing of old pipes, which contributes to landfill waste.
Relining, on the other hand, repurposes the existing pipes, reducing waste and the carbon
footprint associated with manufacturing new pipes.
Understanding the drain pipe relining process can demystify this advanced plumbing
technique and help you appreciate its benefits fully. Here’s a step-by-step overview of what
to expect:
1. Initial Inspection
The process begins with a thorough inspection of the existing pipes using advanced CCTV
camera technology. This allows plumbers to assess the extent of the damage and determine
if relining is a suitable solution.
2. Cleaning
Before the relining can commence, the pipes must be cleaned to remove any debris, roots,
or buildup. This is typically done using high-pressure water jets to ensure the interior surface
of the pipe is smooth and ready for the new lining.
3. Preparation of the Lining
The lining material, usually a flexible tube coated with resin, is prepared. The resin is what
will harden and form the new pipe. This tube is then inserted into the damaged pipe.
4. Insertion and Curing
Once in place, the lining is inflated to fit snugly against the interior walls of the existing pipe.
The curing process begins, which involves either ambient air, hot water, or UV light to
harden the resin. This process typically takes a few hours, depending on the method used
and the size of the pipe.
5. Final Inspection
After the resin has cured and the new lining is fully formed, a final inspection is conducted to
ensure the repair was successful. The result is a smooth, seamless, and durable new pipe
within the old one.
Drain pipe relining is versatile and can be used in various settings, including:
● Residential Properties: Ideal for homes experiencing frequent drainage issues or
those with older plumbing systems.
● Commercial Buildings: Minimises downtime and disruptions, making it a preferred
choice for businesses.
● Municipal Systems: Effective for repairing public drainage systems with minimal
impact on traffic and public spaces.
● Industrial Sites: Suitable for complex industrial drainage systems that require
durable and long-lasting solutions.
While drain pipe relining offers numerous benefits, its success largely depends on the expertise of the professionals performing the job. At DASA, we pride ourselves on our skilled team of certified plumbers who use state-of-the-art equipment and techniques to ensure a flawless relining process.
Our site investigation processes and technologies are supported by the same market-leading, live site reporting options as our drainage teams. This means that we are able to share image, video and audio files between field and review engineers in seconds, greatly reducing the traditional lag-time between attendance, decision and next steps.
DASA engineers attend a property within 24 hours, fully equipped to undertake a variety of non-invasive investigation techniques in the first instance. This might include electro-acoustic ground microphones, tracer gasses or thermal imaging cameras depending on the scenario presented on site.
DASA utilise numerous mains water replacement and repair technologies which enable us to isolate and repair targeted sections with the absolute minimum of above-ground disturbance. This includes, moling and pipe-pulling systems which eliminate the need for traditional trench excavations in many cases.
