## Summary

Most of the damaging geo-hazards recorded in modern history are caused by soil swelling or expansion, making it crucial to properly evaluate a soil's capacity to swell for secure and safe civil infrastructure foundations. To aid geotechnical engineers and researchers in this evaluation process, a dataset of standardized one-dimensional soil swelling on laboratory engineered and natural soils is reported in this study. The dataset includes corresponding properties of these soils such as moisture content, void ratio, specific gravity, unit weight, Atterberg limits, size fractions, soil activity index, and the state of compaction where applicable. The dataset consists of a total of 395 data records on soil swelling potential. Additionally, various corresponding soil properties are included in the dataset: 219 data records of soil specific gravity, 321 data records of initial moisture content, 163 data records of void ratio, 273 data records of dry unit weight, 347 data records of liquid limit, 347 data records of plastic limit, 395 data records of plasticity index, 209 data records of activity index, 339 data records of clay content, 174 data records of silt content 246 data records of optimum moisture content 228 data records maximum dry density and 347 using Unified Soil Classification System (USCS). The determination procedures for soil swelling and related properties mostly follow American Standards for Testing Materials (ASTM) and American Association State Highways Transport Officials (AASHTO) guidelines. Turkish Standards (TS1900) are also referenced in some cases. This dataset aims to assist geotechnical engineers and researchers involved in statistical correlation studies ,data analytics ,machine learning predictions using soft computing methods primarily focused on evaluating soil expansion during the preliminary phases 
of soil investigation and foundation design.
