(DGC) Dickinson Group of Companies specialisies in the installation, repair and maintenance of refractory linings



DGC has 90 years of experience in the specialized field of refractories. The company specializes in the installation, repair, and maintenance of the refractory linings across the complete range of metals smelting, mineral processing, chemical, refining, and thermal power refractory consuming industries.

The company has extensive experience in the installation of all types of refractory materials including; bricklaying, pneumatic gunning, shotcreting, ramming, pumping, vibrocast, and placement of castables, and ceramic fibre products across the complete range of furnace designs.

DGC has carried out the installation of refractories on numerous initial construction and furnace rebuild projects throughout sub-Saharan including; South Africa, Botswana, Zimbabwe, Namibia, Mozambique, Zambia, Democratic Republic of Congo, Tanzania, Malawi, Gabon, Nigeria, Niger, Senegal, and internationally including Israel, United Arab Emirates, Saudi Arabia, Argentina, and Iceland. 


Refractory materials are essentially heat-resistant materials, such as refractory bricks, castables, ramming, or gunning materials, which are designed to maintain their strength at high temperatures. These materials are often used in highly technical industries as the building blocks for large production facilities, such as smelters and incinerators.


Refractory management refers to the management of these production facilities and the processes governing them. Whilst many of these refractory facilities are designed to withstand intense heat, many specialized industries require resistance to other extreme conditions such as acidity, alkalinity, corrosion, abrasion, and erosion. 


The scope of refractory management also includes refractory stock management, offsite refractory material handling, onsite refractory material handling, strategic warehousing, supply & support of refractory management software as well as refractory technical support.

Our team has vast experience, covering a range of furnaces and plant configurations including:

  • Brick Tunnel Kilns

  • Refineries

  • Incinerators

  • Acid Plants

  • Boilers

  • Rotary Kilns

  • Cement & Lime Plants

  • Anode Baking Furnaces

  • Ferroalloy Furnaces

  • Glass Furnaces

  • Aluminum Smelters

  • Copper Smelters

  • Nickel Smelters

Whether you need repairs to current facilities or are looking to establish a new plant, we have a qualified and industry experienced team of engineers, supervisors, bricklayers, gunning crews, and carpenters who have specialized knowledge of all facets of refractory design and construction.


Our belief is that the refractory management is a partnership for the long-term, our team will be available to manage the process with you – from the pre-planning to the ongoing refractory installation and demolition works throughout the service life of the furnace.
