The introduction of CARBOrefit® procedure promotes the preservation of existing structures and prevents demolition, thereby conserving resources and reducing environmental impact. The solution allows structures of societal value to be maintained sufficiently and made usable for future generations. The approach helps the construction industry to effectively meet the needs for affordable housing, functional commercial and industrial buildings, and intact infrastructure.
Strengthening with carbon reinforced concrete offers significant material savings and CO2 emission reductions. Due to a substantially lower concrete usage, material consumption is reduced by up to 85%, and CO2 emissions are cut by up to 50% compared to shotcrete. Overall, the CARBOrefit® procedure ensures efficient resource utilization and leads to substantial cost savings.
The CARBOrefit® procedure requires less labour and allows for a faster construction process compared to conventional strengthening method using shotcrete. The flexibility and light weight of the materials used make on-site strengthening easy to carry out, especially when working overhead. This reduces the strain on the workforce, allowing for smaller crew sizes and highly efficient operations on the construction site.
Carbon reinforcing grids are flexible and can be applied to various curved surfaces with ease. By introducing a thin strengthening layer of only 10-15 millimetres, minimal weight and stress are added to the existing structure. The CARBOrefit® procedure is ideal for renovation projects where the initial load-bearing capacity is limited or the preservation of the original look is required. Furthermore, the use of fine-grained concrete ensures a strong bond between the existing structure and the strengthening layer, eliminating the need for dowelling and the associated damage and risk of penetration.
Carbon has up to six times the tensile strength of steel, which significantly improves the load-bearing capacity of concrete components reinforced with it. The corrosion-resistant nature, combined with excellent ability to control crack width, makes carbon reinforced concrete highly resilient to external influences. These characteristics allow for the application of millimetre-thin strengthening layers that not only enhance the strength but also increase the durability and longevity of existing structures.
The CARBOrefit® procedure is introduced to renovate, strengthen and repair existing civil engineering structures such as buildings, bridges, or tunnels. A millimeter-thin layer of carbon reinforced concrete is applied onto the prepared surface of the concrete component to be strengthened. The procedure can be used in accordance with the German technical approval and general construction technique permit Z-31.10-182 both for constructional function to increase durability and for static strengthening to compensate for structural damage or increased load requirements. Because of its minimally invasive application method without any dowelling, the CARBOrefit® procedure is also ideal for use in historic and listed buildings to enhance load-bearing capacity without significantly altering the appearance.
The CARBOrefit® procedure capitalizes on the innovative composite material: carbon reinforced concrete. A specially developed fine-grained concrete is combined with carbon reinforcement grids. The high performance of carbon reinforcement, coupled with its lightweight and corrosion-resistant nature, results in numerous material advantages and application possibilities that make the CARBOrefit® procedure highly beneficial for the preservation of structures.
Design: The CARBOrefit® method may be designed and dimensioned by any planner in Germany on the basis of approval Z-31.10-182. Our planning guide contains valuable tips and information in addition to the approval. We also recommend voluntary participation in one of our design training courses - here you will learn all the relevant information on structural maintenance with carbon reinforced concrete in a particularly time-efficient manner and gain a decisive knowledge advantage. Execution: To carry out the CARBOrefit® procedure in accordance with the approval, the relevant construction companies must have a CARBOrefit® certificate of suitability. This can be obtained as part of a two to three-day training course and subsequent certification by GÜB.
Yes, the CARBOrefit® procedure offers a number of significant advantages. The procedure enables significant time and resource savings through a reduction in construction time and the demand for labor and materials. Another economic benefit is the extended lifetime of the renovated buildings, as deteriorated structures can be efficiently preserved. In addition, the gain in usable space as a result of reduced layer thickness increases the efficiency of the structures. A particular advantage is the project-specific configurability of the materials used. By adjusting the type and geometry of the reinforcement grids, a material-efficient and cost-effective solution can be found for each construction project. Recent projects have repeatedly shown that strengthening with the CARBOrefit® procedure is even more economically advantageous than using conventional methods.
The CARBOrefit® procedure is still applicable in many cases where individual project parameters deviate from the applications regulated in the scope of the approval (e.g. use in exterior areas or bridges). In these cases, a project-related approval (ZiE) is required, however, this can be obtained in a very cost and time-efficient manner by referring to the approval, available test results and practical applications.
