Biogas Services
Radius Subterra delivers specialist pipeline engineering services for biogas and biomethane projects from the production facilities to grid connection points.
Our teams draw on extensive gas network experience to provide safe, controlled installation, connections, maintenance, and interventions on both polyethylene (PE) and metallic pipelines, ensuring compliant integration with existing gas infrastructure across the UK and beyond.

Flowstopping
We deliver controlled live flowstopping solutions for biogas pipeline construction, modification, and maintenance. Drawing on extensive expertise from gas distribution networks, our teams safely isolate polyethylene (PE) and metallic pipelines, enabling repairs, connections, and alterations without full system shutdowns, minimising disruption and maintaining operational continuity.
Pipeline Repair & Maintenance
Radius Subterra provides specialist pipeline repair and maintenance for biogas infrastructure, leveraging experience from gas distribution and energy networks. We support planned maintenance, defect remediation, damage repair, and asset life extension on polyethylene (PE) and metallic pipelines, ensuring safe operation, regulatory compliance, and long-term integrity of biogas transmission and connection pipework.
Under-Pressure Connections
Radius Subterra delivers live under-pressure connections on biogas and biomethane pipelines, enabling tie-ins without depressurising or interrupting operation. Our teams install polyethylene (PE) and metallic connections across diverse materials, diameters, and operating conditions, supporting plant modifications, grid injections, and network integration safely, efficiently, and in compliance with industry standards.
Pipework Installation & Mainlaying
We install and connect biogas pipeline infrastructure from production facilities to grid connection points. Our teams install polyethylene (PE) and metallic pipeline systems, including new mains, tie-ins, and associated pipework using controlled construction methods for live assets, complex layouts, and operational environments. All works are delivered with full QA documentation and completion reporting.
Pre-Insulated Pipework
Radius Subterra installs, repairs and replaces pre-insulated pipework for biogas plant operations, including process heating, digestate temperature control, and heat recovery networks. Leveraging experience from energy, district heating, and industrial sectors, our teams deliver durable, efficiently installed systems aligned with site and operational requirements.
Pressure Testing
We carry out controlled pressure testing and commissioning of biogas pipelines to verify integrity, strength, and system readiness before handover. Our procedures follow established gas network practices, proving pipelines safe, compliant, and fit for service before introduction to the biogas process or grid connection.
Pipe Cutting
Radius Subterra delivers controlled cold-cutting of polyethylene (PE) and metallic pipework across biogas systems, including plant pipework, export lines, and gas network connections. Our spark-free pipe cutting methods support safe modification, repair, connection, and decommissioning on live or inactive pipelines, minimising risk and maintaining system integrity.
Manufacture & Fabrication
We support biogas projects through the manufacture and fabrication of bespoke pipework components to suit site-specific layouts and interfaces. We fabricate polyethylene (PE) and metallic manifolds, tee pieces, transition sections, complex bends, and non-standard assemblies, meeting operational, safety, and installation requirements from plant infrastructure to grid-connection points.
Engineering & Project Management
We provide engineering and project management support for biogas infrastructure, including pipeline routing, connection design, and coordination through to final gas grid injection points. Our teams work closely with clients and stakeholders to deliver safe, compliant, and efficient delivery from plant outlet to network connection.
