Repair preferences among drainage professionals
In a recent survey conducted by NADC (National Association of Drainage Contractors) and DrainSafe, over 400 drainage industry professionals weighed in on the preferred methods of offering drainage repair options to customers. The results offer valuable insights into current trends within the drainage and repair industry, highlighting the increasing preference for more efficient, less disruptive solutions.
Key findings: patching and lining vs. open cut excavation
When asked about their preferred drainage repair methods, respondents were given the choice between two primary options:
1. Patching and Lining (where effective) 2. Open Cut Excavation and Repair The results were clear and telling:
• 76.3%of professionals preferred offering patching and lining as a repair option, provided it is a viable solution for the situation.
• 23.7%chose open cut excavation as their preferred method of repair.
These figures underscore the growing trend toward trenchless technologies and the desire to minimise disruption during repair work.
Why the shift toward patching and lining?
Patching and lining, which includes methods such as cured-in-place pipe (CIPP) and cured-in-place repair (CIPR), have become increasingly popular due to their price efficiency and minimal impact on the surrounding area. Here are some reasons why so many professionals are opting for these trenchless methods:
1. Minimal disruption to property one of the main advantages of patching and lining techniques is
the minimal disturbance to the property itself. Traditional open cut excavation often requires digging large trenches through driveways, gardens, or even roads. In contrast, trenchless technologies allow for repairs to be made without disturbing the surface, reducing the need for costly and time-consuming restoration work after the repair.
2. Cost-effective
The reduced need for excavation, along with quicker installation times, can lower labour costs, and reduce the need for additional materials and restoration work.
3. Speed and efficiency
Patching and lining repairs can often be completed in a fraction of the time it takes to carry out traditional excavation and repairs. This means less downtime for customers and faster resolution of drainage issues, which can be particularly important for businesses or homeowners experiencing severe drainage problems.
4. Durability and long-term ssolution When done correctly, patching and lining repairs can provide a

long-lasting solution to drainage problems. CIPP lining, for example, creates a seamless, durable, and corrosion-resistant pipe that extends the lifespan of the drainage system for many years. This longevity offers peace of mind to customers, knowing that their drainage issues have been resolved with a sustainable, low- maintenance solution.
The case for open cut excavation
Despite the clear preference for patching and lining, 23.7% of professionals still favour open cut excavation, particularly when trenchless methods aren’t suitable. Open cut repairs remain necessary in certain circumstances, such as when the pipe is severely damaged or misaligned beyond what patching and lining can effectively repair.
Open cut excavation also allows for more extensive repairs or upgrades to the drainage system, such as upsizing or improvements to the overall structure of the system.
The future of drainage repair
The results of this survey suggest that the drainage repair industry is evolving, with an increasing preference for less invasive, more efficient methods of fixing drainage problems. As technology continues to advance, we can expect even more innovative trenchless solutions to emerge, further transforming the landscape of drainage repair.
For professionals in the industry, staying up to date on these emerging technologies and customer preferences will be key to remaining competitive. Offering a range of repair options—tailored to the specific needs of each customer—will ensure that businesses can meet the varied demands of their clients while delivering high- quality, cost-effective solutions.
Conclusion
The clear trend revealed by the NADC and DrainSafe survey is that the drainage industry is shifting toward more efficient, minimally invasive repair techniques. With 76.3% of respondents favouring patching and lining, it’s clear that the future of drainage repair lies in innovative trenchless technologies. As these solutions continue to evolve, both industry professionals and customers will benefit from faster, more affordable, and less disruptive repair options that preserve the integrity of their properties.
By understanding these trends, drainage professionals can make informed decisions when recommending repair options to their customers—ensuring that they provide the most effective and least disruptive solution possible.
