Substation Plinth Services
We deliver full-service substation plinth construction and alterations across the UK. Our work supports both new substation builds and upgrades to existing infrastructure. From initial excavation to final surfacing, we manage the entire process in-house.
​
Typical works include site preparation, excavation, setting out and forming the plinth base, installing conduits and grating, pouring and finishing concrete, then applying the specified surface finish – usually tarmac. Where needed, we also carry out reinstatement and landscaping around the plinth to return the site to a tidy and safe condition.
​
Every plinth is built to meet client and DNO standards, with a strong focus on safety, precision, and long-term durability.
Excavate and Reinstate Ltd constructed a durable substation plinth in Liverpool, which was completed to a high standard. The process began with precise excavation and compaction of the sub-base, followed by concrete blinding and shuttering installation. A reinforced concrete base was poured, brickwork and ducting were added, and the area was backfilled with compacted Type 1 MOT. Earthing and steelwork, including earthing clamps, were securely installed. The project was finished with the top base plinth concrete pour, creating a strong, level foundation ready for substation installation.
Excavate & Reinstate Ltd has completed the full excavation and construction of a substation plinth in Birmingham, delivering a high-quality finish in line with the client’s design specifications. The works began with a careful and controlled excavation, ensuring all underground services were identified and protected. A clean and stable base was established with the installation of concrete blinding, followed by the secure placement of shuttering to prepare for the base concrete pour.
Once set, the base plinth concrete was poured and levelled with precision, providing a strong and durable foundation. Blockwork was then constructed to the exact requirements of the client’s design, with each course laid accurately to ensure structural integrity and alignment. Type 1 MOT was subsequently installed and compacted in 200mm layers, methodically brought up to the block level to guarantee long-term stability.
To complete the works, top plinth shuttering and steel reinforcement were installed in full accordance with the substation design. All stages were carried out to a high standard of workmanship, with a strong emphasis on safety, compliance, and attention to detail throughout the project.
Excavate & Reinstate Ltd is progressing well with the substation plinth project in Yorkshire, having successfully delivered all key groundwork and structural phases to date. The area was first excavated, levelled, and compacted using a whacker plate, creating a solid base for construction. Concrete blinding was then laid, and markers were set out to define the precise siting of the plinth.
​
Shuttering was constructed to the required dimensions, including a letterbox opening for service routes. Steel reinforcement was installed, and the shuttering securely braced, ready for the concrete pour. The concrete was placed and finished to a high standard, then allowed to cure under controlled conditions.
​
With the concrete now fully cured, the shuttering has been removed, exposing a clean, well-formed plinth. Ground preparation is currently underway around the structure, readying the site for the next phase of substation installation. The project continues to move forward with precision and attention to detail at every stage.
Excavate & Reinstate Ltd has successfully delivered the construction of a substation plinth as part of a large-scale project in Devon. The works began with a carefully executed excavation to the required depth and footprint, with all underground services identified and protected. A clean, level layer of concrete blinding was then laid to provide a stable working base.
​
A large shuttering structure was erected to suit the design, including provisions for duct entries and a letterbox opening. Ducting pipework and steel reinforcement were installed with precision, ensuring full compliance with structural and service requirements. The concrete pour followed, with the mix carefully placed and compacted to form a strong, smooth finish. After curing under controlled conditions, the shuttering and temporary earth supports were removed.
​
With the structure fully exposed, earthing cables were installed on a prepared bed of sand, ensuring proper protection and alignment. The completed concrete plinth, with its accurately formed letterbox opening, now stands ready to receive the substation and its associated components, built to exacting standards throughout.
