Expansion Joint Maintenance, Cladding & Insulation

Utilising a combination of Zenith specialist access techniques, we provide a safe and extremely cost effective solution for the supply and replacement of expansion joints. Very often access proves to be an issue. Our world class structural engineers design innovative access methods proving to save significant time, which is a crucial aspect of any turnaround.

In addition, we perform a comprehensive range of industrial cladding services to structures throughout the industrial sector.

Mechanical & Welding Services

Working in demanding industrial environments including refineries, power stations and cement plants and often having to perform welding repairs during tight shutdown periods, Zenith provides a comprehensive range of welding repair services.

Whether welding is required at low level or even where welding at height requires the design and installation of safe and innovative access, Zenith provides industry leading solutions.

Zenith is a trained and approved installer of the LOKRING® system and we are able to install:

• MAS-3000 Carbon Steel Series Pipe Fittings

The main advantage in using the LOKRING® method is that it eliminates the need for hot works at height in a refinery environment or offshore.

Maintenance – Steelworks

Zenith has a wealth of experience in this essential field of activity. We have decades of experience in the maintenance and repair of structures across steelworks including industrial chimneys, natural draught cooling towers, flares and other tall structures.

Maintenance & Repair

Zenith specialises in carrying out repairs throughout all industrial, commercial and residential sectors. We provide all of the trades and skills required to maintain and repair buildings and structures. We work for the world’s leading companies ranging from petrochemical, power, steel and cement to academia, hospitals, local courts and much more.

Maintenance – Industrial Chimneys

The inspection, maintenance, repair and demolition of industrial chimneys remains our core activity. The successful external and internal refurbishment of these structures requires a thorough survey to establish the true extent of the repair work required. A full digital survey is the first stage in a five-phase operation that includes access equipment design, installation, load testing and repairs. We offer an online hot camera inspection as digital photography can reveal weaknesses and defects that require attention, for example to the interior lining and brickwork, baffle walls and flue inlets. Critically, it also enables engineers to plan in advance of a shutdown.
