Void Filling & Decommissioning

GCE provides specialist void filling and decommissioning solutions for energy, civil engineering, marine, and industrial infrastructure projects. We deliver safe, controlled and efficient filling of redundant assets, abandoned structures and underground or submerged voids using engineered grout systems designed to suit the project requirements.

Whether the objective is to stabilise, abandon, protect or permanently decommission an asset, we work with clients to develop a practical grouting solution that is technically robust and suited to site constraints, programme demands and environmental considerations.

Our capabilities include:

• Filling of redundant pipelines, ducts and annuli 
• Tunnel, shaft and culvert void filling 
• Decommissioning of marine and offshore assets 
• Stabilisation of underground chambers and inaccessible voids 
• Filling around structures to prevent collapse, settlement or water ingress 
• Supply and placement of low-density, pumpable and high-flow grout systems 
• Delivery of works using specialist mixing, pumping and monitoring equipment 

Why GCE

Our team combines specialist grouting knowledge with practical site experience to deliver void filling and decommissioning works safely and efficiently. We understand that these projects often involve restricted access, challenging geometries, live environments and strict environmental controls. Our approach focuses on selecting the right grout properties, pumping methodology and sequencing to achieve complete filling and reliable outcomes.

We can support projects from early planning and methodology development through to mobilisation, site delivery and quality documentation.
