Comprehensive Commercial Drainage Solutions in New Zealand
DAVIES, offers specialised commercial drainage solutions to businesses and councils throughout New Zealand. With our fleet of specialised vehicles and equipment, we provide quality drain maintenance services to ensure efficient drainage systems.
CCTV Inspection and Reporting
We utilise state-of-the-art CCTV technology to conduct thorough inspections of drainage pipes. Our inspections provide clear insights into pipe conditions, allowing us to identify issues and implement effective repair and maintenance strategies.
Advanced Capability
Our CCTV inspection capabilities include:
- In-pipe inspection to identify damage and compromises in pipe integrity
- Dye Testing for detecting the flow of water throughout drains or pipes connected to a drain system
- Detailed reporting using industry-standard protocols
- Identification of pipelines and issues within difficult to access locations geographically
Why CCTV?
CCTV Pipe Inspections are the most cost-effective option to determine the condition of your underground pipeline infrastructure. Davies’ CCTV cameras and mobile units can get into pipes of virtually any size and provide clear, high-resolution imagery to show exactly what’s going on inside those pipes.
The advantage of Davies CCTV Systems is our technology that enables us to provide you with relatively high accuracy the position of issues identified within pipelines including but not limited to the identification of any faults, construction features, or buried access points.
All our CCTV Inspections, follow the guidelines outlined in the New Zealand Gravity Pipe Inspection Manual – Version 3 or 4, depending on the specific requirements of the local council. Coupled with state-of-the-art Wincan XV Advanced reporting software Davies can report on the pipeline’s condition in real-time.
Once inspection is completed the captured data undergoes a quality review by our management team before being shared with our clients. We’ll provide you with the means of access to the data, even via flash drive if urgent.
Davies is dedicated to delivering exceptional services, utilising cutting-edge technology. This dedication is one of our key attributes as your reliable, efficient partner for maintaining all your stormwater and wastewater assets.

Cured In Place Pipe (CIPP) patching and short-length replacement
We offer CIPP patching and short-length replacement services to address damaged sections of drainage pipes. Our innovative techniques ensure efficient repairs with minimal disruption, without the necessity of digging up long tracts of roading, pavements, and parks to access pipes for repairs.
What we can do:
- Inversion liners, up to DN500mm diameter and up to 150m pipe section length.
- Winch in Place covers all diameters and lengths of pipe.
- Patch repairs are used for smaller pipe repairs, such as cracks or where a small portion of the wall has been damaged. Excellent for assisting with pipeline longevity.
Lateral Junction Repairs (LJR)
Using advanced technologies, we provide lateral junction repairs to address cracks and leaks in pipe junctions. Our LJR services ensure long-lasting solutions for improved drainage performance.
To undertake a LJR, we:
- Use Top Hat technology to rehabilitate the joint with durability and longevity.
- Davies uses seamless glass fibre laminate for LJR repairs.
- The diameter we can undertake is an LJR of 150mm to 600mm.
