This blog from Rothoblaas briefly details how TC Fusion presents an innovative solution for timber-to-concrete connections.

In the realm of construction, prefabrication has gained immense popularity due to its efficiency and cost-effectiveness. A crucial aspect of prefabricated structures is the seamless integration between different building elements, such as timber and concrete. Addressing this need, TC Fusion presents an innovative solution for timber-to-concrete connections. With its VGS, VGZ, and RTR full-thread connectors, TC Fusion offers exceptional strength and stiffness, enabling secure transmission of stresses between timber and concrete elements. This article explores the benefits and applications of TC Fusion, highlighting its role in enhancing the structural integrity of prefabricated buildings.

Timber and concrete have long been used as primary construction materials, each offering distinct advantages. However, joining these materials efficiently has historically posed challenges. Traditional connection methods often lack the strength and durability necessary for modern construction demands. With the rise of prefabricated structures, the need for reliable timber-to-concrete connections has become even more critical.

TC Fusion introduces a game-changing solution to the timber-to-concrete connection conundrum. The VGS, VGZ, and RTR full-thread connectors have now obtained certification for use in any application where timber elements must transmit stresses to concrete elements. These connectors facilitate the integration of timber and concrete prefabrication processes seamlessly.

The innovative approach of TC Fusion involves reinforcing bars embedded within concrete castings, accommodating the full-thread timber connectors. After the timber components are installed, supplementary casting completes the connection, ensuring exceptional strength and durability. This revolutionary technology enables secure connections between cross-laminated timber (CLT) panels, providing remarkable resistance to shear, bending moment, and axial stress. Notably, TC Fusion's compatibility with other products like SPIDER and PILLAR further enhances its versatility and applicability in various structural configurations.

The utilization of TC Fusion in timber-to-concrete connections offers a multitude of benefits. Firstly, it significantly enhances the structural performance of prefabricated buildings by providing exceptional strength and stiffness. The full-thread connectors effectively distribute loads, reducing stress concentrations and improving the overall durability of the structure.


Furthermore, TC Fusion streamlines the construction process by seamlessly integrating timber and concrete prefabrication techniques. The connectors enable efficient and rapid assembly, leading to substantial time and cost savings. By expediting construction timelines, TC Fusion contributes to the overall project efficiency and enhances productivity.

Moreover, TC Fusion's compatibility with CLT panels makes it an ideal solution for modern timber-based construction. CLT panels have gained popularity due to their sustainability, energy efficiency, and design flexibility. The exceptional strength and stiffness provided by TC Fusion connectors further amplify the structural advantages of CLT, ensuring reliable and resilient buildings.


The versatility of TC Fusion opens up a wide range of applications in the construction industry. Its use is particularly prominent in multi-story buildings, where the integration of timber and concrete elements is crucial for structural stability. From residential buildings to commercial structures, TC Fusion offers an optimal solution for connecting timber floor systems, walls, and ceilings to concrete cores and foundations.

In addition to its current applications, TC Fusion holds great potential for future development. As the demand for sustainable construction continues to grow, the combination of timber and concrete offers an environmentally friendly alternative to traditional building materials. TC Fusion's ability to seamlessly integrate these materials positions it as a key player in the construction industry's sustainable future.


TC Fusion represents a revolutionary advancement in timber-to-concrete connections for prefabricated structures. By utilizing the VGS, VGZ, and RTR full-thread connectors, this innovative solution ensures exceptional strength, durability, and efficiency in joining timber and concrete elements. With its ability to enhance the structural integrity of prefabricated buildings, TC Fusion opens up new possibilities for sustainable construction practices. As the industry continues to evolve, TC Fusion's compatibility with CLT panels and other building components positions it as a crucial player in shaping the future of construction.
