In this study; the geometrical stability of solid wood parquet was searched. For determining the geometrical stabilization of specimens pre-tests and tests were carried on. Determination of density, radial and tangential shrinkage and swelling tests were carried on as pre-tests. In the laboratory tests; the specimens were conditioned at different relative humidity values, then the geometrical stability changes were measured. In this stage; different physical properties were created on some groups of specimens. Here the aim was searching the effect of different physical properties on geometrical stability. After the experiments; the results were evaluated with the literature and statistical test diagnosis. As a result; it is determined that grooving channels to solid wood parquets is not advantageous in improving the geometrical stability but the geometrical stability of the specimens which were scraped successively improved. Also; the geometrical stability of the specimens which are exposed to different climate conditions successively improved.
