Moisture protection is essential for wooden constructions to prevent long-term damage. Basically, the designer has two possibilities to prevent moisture damage. The first is the building physics strategy, which involves the sensible selection of the sequence of layers, layer thicknesses and materials in such a way that the water content in the relevant layers remains permanently below a permissible limit. The risk of such moisture ingress is typically determined by calculations or simulations. On the other hand, constructive wood preservation aims at eliminating the effects of moisture through structural measures. For this, proven detailed solutions are relied upon. The increasing variety of detailed solutions and the changing requirements make it difficult to find an optimal solution, whether in the area of single-family houses or in public multi-storey residential and commercial buildings. User comfort requirements or barrier-free construction demand a level balance between the inner floor covering and the outer entrance area. It follows that the installed foot threshold of the exterior wall is not only below the recommended level, but also below ground level. The present article examines the wood moisture content within an exterior wall in solid wood construction with cross laminated timber in the area close to the base on the basis of a two-year in situ measurement. The measuring sensors were arranged in the individual layers and three different heights. The results show an increased wood moisture content, especially in the most critical measurement series.
