Purpose: The topic of this article is the use of anchors bonded in the outer walls of threelayer large slab panel buildings in Poland. Design/methodology/approach: Comprehensive laboratory tests of anchoring systems bonded in various configurations were carried out. On this basis, the theoretical load capacity of the new bonded anchorages can be estimated. Findings: These considerations are the aftermath of the current problem of the former large slab panel buildings in Poland, and more specifically the risk of detachment of the external textured layer in the walls of three-layer large slab panel buildings. Research limitations/implications: The presented variants of experimental research and their comparison with the MES analysis indicate the directions of conduct in strengthening three-layer walls. It should be remembered that the use of additional reinforcement anchorages is practically a necessity, as the next stage of renewing large slab panel buildings is their thermo-modernization. Practical implications: This process results in an increase of the load on the external textured layer, and hence also on hangers. Originality/value: Experimental research is aimed at determining the optimal variant of application of bonded anchors.
