Award winning land drainage pipe rehabilitation
Lining & Perforating Restoring Land Drainage
In working to reduce the asset management costs of one of our key customers, Waterflow Plc have developed a technique to rehabilitate land drainage.
The drain is initially quickly lined using our UV light cured GRP liner. Once the liner has cured hard, both the liner and the existing host pipe are perforated using one of our patented perforating robots. Our UKSTT award winning solution can restore land drainage in a single shift with no digging or heavy plant required.
The time, cost, disruption and environmental benefits of this solution have made it our fastest growing business stream.
UV Cured GRP pipe lining
The Waterflow Group has always been a company at the forefront of cured in place pipe for the repair and renovation of broken and defective drains and sewers. Recent developments in technology have produced a new and innovative method for cured in place pipe lining, the process is faster and the materials are stronger than standard CIPP.
The process involves the use of UV light to cure the resin impregnated liner that is held in position by air pressure, rather than by water, during the very fast curing process.
This new pipe rehabilitation process offers significant advantages relating to quality, efficiency and environmental impact, these can be identified as:
- Bespoke design for specific structural requirements of each job
- Pre curing inspection by CCTV ensuring a high quality finish on every installation
- Cure time of 1 metre per minute can be achieved
- Lining can be undertaken during short night shifts
- Self contained and highly portable enables linings to be installed in difficult and remote sites.
- Negligible styrene emissions.
- Minimal flow control required due to the speed of installation.
- Significantly exceeds all current material standards for strength and longevity.
- WRc APPROVED
Our in house capabilities are extensive and this, combined with our innovative pipe and sewer rehabilitation techniques, enable us to tackle any aspect of drain or sewer maintenance, repair or renovation.
Pipe reaming
Where pipes are displaced or partially collapsed pipe reaming can be an effective no-dig solution for repair. Waterflow Plc provide a range of pipe reaming systems from miniaturised catch-pit / manhole based systems to HGV mounted units.
The operation is conducted with a directional drilling machine and a reamer that grinds and pulverises the existing pipe. The excess peripheral material is flushed and removed with the drilling fluids and the HDPE pipe of the required size pulled into place simultaneously.
This method avoids the ground heave and risk to other infrastructure associated with pipe bursting, making it a very effective technique in areas with significant services and structures above or near to the pipe being rehabilitated.
