With CARBOrefit® we are committed to the sustainable transformation of the construction industry. To achieve this, we utilise the potential of composite materials - in particular the innovative material carbon reinforced concrete.
CARBOrefit® represents a sustainable and resource-saving strengthening solution that simultaneously secures the existing structure and increases its load-bearing capacity and durability. CARBOrefit® can be used efficiently, economically and in a number of different ways. The CARBOrefit® procedure provides a solution that can be used to achieve climate targets in the construction industry and leave a liveable environment for future generations.

The CARBOrefit®-procedure for structural strengthening using carbon reinforced concrete
Carbon reinforced concrete, a unique composite building material consisting of two high-performance components – fine-grained concrete and carbon reinforcing grids – is characterized by its extreme performance and durability. The carbon reinforcement carries tensile loads, while in retrofitting applications, the concrete cover ensures a strong bond with existing structures and is capable of withstanding compressive forces. The high chemical resistance of non-metallic carbon reinforcement eliminates the corrosion issue typically associated with steel reinforced concrete and shotcrete. With carbon reinforced concrete, this problem becomes a thing of the past!
The innovative CARBOrefit® procedure for strengthening harnesses the exceptional advantages of high-performance composite carbon reinforced concrete, offering an effective solution for the preservation and sustainable development of concrete structures.
Existing concrete structures can be satisfactorily strengthened, renovated, or repaired by applying a carbon reinforced concrete strengthening layer to the surface of available steel reinforced concrete elements. Thanks to the high tensile strength and low density, as well as excellent corrosion resistance of carbon reinforcement, thin layers of just a few millimeters are fully sufficient to restore or even improve the strength of the original concrete elements. The need for over-dimensioned concrete cover for reinforcement protection becomes obsolete. In retrofitting applications, carbon reinforced concrete distinguishes itself by demonstrating excellent bonding behavior and minimal crack widths, leading to enhanced durability. Additionally, a high flexibility of the carbon reinforcing grids allows for effortless strengthening of various curved surfaces. The CARBOrefit®-procedure results in a non-destructive and delicate carbon reinforced concrete strengthening layer.
Thanks to its rapid construction process, outstanding durability, and a lifespan exceeding 100 years, it is also economically superior to other conventional measures presently in use. Another significant benefit of carbon reinforced concrete include substantial material and weight savings. When applied to existing concrete structures for strengthening and renovation, a single 10 mm strengthening layer of carbon reinforced concrete can deliver a notable increase in load-bearing capacity, similar to what one would achieve with a 70 mm thick shotcrete application. This reduction in material usage not only minimizes stress on existing structural members but also preserve the structure’s appearance.
Moreover, carbon reinforced concrete significantly reduces the environmental and climate impacts associated with the resource-intensive and emission-heavy construction industry. Beside the structural design, the transportation and on-site operations (workload per person, among others) are also positively affected. These attributes make carbon reinforced concrete a unique and sustainable solution, particularly for strengthening and renovation projects. The CARBOrefit®-procedure is an exceptionally resource-efficient retrofitting solution that opposes demolition and promotes the preservation of buildings and construction works. Its multifaceted benefits can contribute significantly to the transformation of the construction industry towards sustainability.
Carbon reinforced concrete offers diverse applications in structural strengthening and renovation. As a thin, high-performance strengthening layer, it is an excellent choice for historic preservation, where it can be applied to protected historical objects with minimal impact on the original building contour. Furthermore, its potential extends beyond historic sites and can be used effectively in buildings, bridges, waterworks and underground constructions. Numerous practical projects have already demonstrated the feasibility and efficiency of CARBOrefit®.
Let’s take a step forward in building the future with CARBOrefit® – a minimally invasive method that saves construction works from demolition, conserves resources, and reduces carbon emissions!

Durability
High Strength
With approx. 3000 N/mm2 , carbon reinforcement is characterised by a tensile strength that is up to six times higher than conventional reinforcing steel (approx. 500 N/mm2). This leads to a significantly improved load-bearing capacity of the reinforced components.
Material Savings
The use of carbon reinforced concrete can save a considerable amount of material. Compared to shotcrete, the material requirement is reduced by up to 85 %. This results from the reduced amount of concrete, which is achieved by the corrosion resistance of the carbon reinforcement.
Reduced Structural Load
Due to the thin layer structure of only 10 – 15 millimeters, less additional weight is introduced into the existing structure. This is particularly advantageous for the renovation of listed buildings or structures where additional weight would be problematic. Moreover, a structure-preserving bond between the existing structure and the reinforcement layer is achieved, which does not require any doweling.
Flexibility
The flexible carbon grids allow for the reinforcement of highly curved components, which is often difficult with traditional methods.
Easy Application
Due to the flexibility and weight of the materials used, the execution on the construction site – especially for overhead work – is easily manageable. This protects the workforce, allows for smaller crew sizes, and enables clean work on site.
Time and Cost Efficiency
Compared to conventional shotcrete, the workload for the CARBOrefit® procedure is lower, enabling a faster construction process. This leads to efficient use of resources and can save costs.
Sustainability
The resource-efficient method of the CARBOrefit® procedure allows existing buildings to be preserved and saved from demolition, contributing to the conservation of resources and reduction of environmental impacts.
CO2 Reduction
A significant reduction in CO2 emissions is achieved. Compared to traditional methods like shotcrete, a reduction of up to 50 % in CO2 emissions can be achieved.
Durability
Carbon reinforced concrete is particularly resistant to corrosion and effectively withstands external influences, leading to increased longevity and durability of the reinforced structure.
