Similar to the broad use of the seismic methods to identify the layers of soil and the distance strike the bedrock, initial site properties require geophysical techniques to assess them. This research was carried out to investigate the properties of the subsurface composition of a backyard area in Universiti Teknologi Malaysia, Johor campus, guided by the principles of this process. The Evaluation of seismic data analyzed using ZondST2D computer software by calculating the first arriving time of the propagated seismic wave throughout soil layers to obtain a subsurface prototype. The examined subsurface profile was composed of four layers displaying the weathering grade level of scales between 600 m/s to 4000 m/s depending on Malaysia’s rock mass categorization. Weathering concentrations were observed to be declining at higher depth, with increased density of the material and reduced seismic velocity dampness. It was found that only for shallow subsurface compositions which is far from interference and noise, can the analysis of seismic refraction be conducted progressively.
