No Dig Blockage Removal Services
RGL Services delivers no dig blockage removal across the UK using ultra-high-pressure water jetting at up to 2,800 bar. Operating since 1984, we cut and remove solid obstructions such as concrete, foundation piles, sheet piles and structural debris from pipes, sewers, culverts and overflow systems without excavation. Our purpose-built rigs work where conventional drain jetting fails and in pipes as small as 95mm in diameter.
As specialist no-dig obstruction removal contractors, we combine CCTV survey, in-pipe rig deployment and precision UHP cutting under one contractor, then clear the cut material by vacuum or jetting. Rentajet is mobilised nationwide, with Romsey, London and Manchester coverage and a direct response service for blocked drainage and flood-prevention systems.
Why Asset Owners Specify No-Dig Removal Over Excavation
When solid blockages such as concrete, foundation piles or structural debris obstruct a pipe, sewer or culvert, conventional drain jetting often fails completely. The traditional alternative is excavation, which is expensive, slow and highly disruptive. It means road closures, traffic management, reinstatement and major disturbance to infrastructure, sites and the surrounding environment, often for an obstruction only metres below the surface.
No-dig blockage removal removes that constraint. A purpose-built rig is deployed into the pipe, secured in place, and precision UHP cutting nozzles slice cleanly through the obstruction at 2,800 bar. The cut material is then removed by powerful vacuum or conventional jetting, returning the pipe to full capacity. The method works in pipes as small as 95mm and succeeds where standard high-pressure jetting has failed.
That combination is what gets no-dig removal specified on drainage, sewer and flood prevention systems where excavation would be disproportionately expensive and disruptive for the blockage involved.

Benefits of No-Dig Blockage Removal
No-dig UHP pipe blockage removal changes the cost, disruption and environmental profile of clearing a solid obstruction compared with excavation
Avoids costly digging, road closures and major disruption to sites, roads and properties.
Minimise downtime for critical drainage, flood prevention, and sewer systems
Successfully clears concrete, metal, and solid obstructions that defeat conventional jetting
Reduced surface disturbance, less waste, and lower carbon footprint
Remote or fixed-rig precision cutting with experienced operators
No-Dig Removal vs Excavation
Excavation remains the default where specialist no-dig capability is not available. It is familiar to civils contractors but is expensive, slow and disruptive, and on buried services it can mean road closures, reinstatement and major environmental disturbance. No-dig UHP removal carries an equipment day rate but removes the digging, closure and reinstatement burden, which on most buried-obstruction scopes makes it the lower total cost route.
| Factor | No-Dig UHP Removal | Excavation |
|---|---|---|
| Surface disturbance | None, in-pipe only | Major, full dig and reinstatement |
| Road closures | Usually none | Often required |
| Effective on concrete and piles | Yes, precision cutting | Yes, but by digging out |
| Minimum pipe size | From 95mm diameter | Limited by access to dig |
| Restoration of flow | Fast | Slow, after reinstatement |
| Environmental impact | Low | High, spoil and disturbance |
| Cost on buried services | Lower total cost | High, with reinstatement |
| Disruption to operations | Minimal | Significant |
Applications of No-Dig Blockage Removal
No-dig blockage removal is specified wherever a solid obstruction blocks a pipe, sewer or culvert and excavation would be disproportionate. Rentajet delivers across three primary application sectors.
Sewers and Drainage Networks
Clearance of concrete, debris and solid obstructions from public and private sewers and drainage networks, restoring flow without excavation
Flood Prevention and Overflow Systems
Removal of piles and obstructions from flood-plain overflow pipes and flood-prevention systems where blockage threatens drainage capacity.
Culverts and Buried Infrastructure
Clearance of hard deposits and obstructions from culverts and buried drainage on highways, rail and civil infrastructure sites.
Industries We Serve

Our No Dig Blockage Removal Process
Rentajet follows a five-step process on every no-dig removal mobilisation, from initial enquiry through to flow restoration.
01. CCTV Survey and Blockage Assessment
We carry out a CCTV survey to locate and assess the obstruction, the pipe and the access. A method statement and risk assessment are produced covering confined drainage, water
management and WJA Code of Practice compliance
02. Rig Mobilisation and Set-Up
A purpose-built rig is mobilised and deployed into the pipe or sewer. Pump units run at up to 2,800 bar, with all hoses, nozzles and connections inspected under WJA Code of Practice.
03. Rig Securing and Commissioning
The rig is secured in position against the obstruction. Cutting pressure, nozzle configuration and feed are set and confirmed before cutting starts.
04. Precision Obstruction Cutting
UHP cutting nozzles slice cleanly through the obstruction, monitored by camera. The cut material is then removed by vacuum or conventional jetting to return the pipe to full bore.
05. Verification and Handover
A final CCTV survey verifies the pipe is clear and at full capacity. A photographic and survey record is issued to the client confirming flow restoration
No Dig Blockage Removal FAQs
Cost depends on the obstruction type and size, the pipe diameter and length, and the access. No-dig removal carries an equipment day rate but typically costs far less in total than excavation once digging, road closures, reinstatement and disruption are accounted for. Contact us for a project-specific quotation.
Concrete, foundation piles and sheet piles including Larsen piles, structural debris, and hard solid deposits in pipes, sewers and culverts. We also clear debris from sensitive inclinometer tubes without damaging the tube.
Our method works in pipes as small as 95mm in diameter, with rig and tooling matched precisely to the bore. The CCTV survey confirms the pipe size and the best deployment approach.
No. Precision UHP cutting is controlled and monitored by camera so the nozzle cuts the obstruction without damaging sound pipe. The rig is secured in position to keep the cut accurate throughout.
Yes. Removing foundation piles and sheet piles that have penetrated and blocked drains or flood-plain overflow pipes is one of the most common reasons the service is specified, and it is done in place without excavation.
