This paper is aimed at using up-hole method of seismic refraction survey to investigate the thickness of the weathering layer as well as the velocity of seismic waves through the layer. The first events to arrive at the geophones on a refraction profile had travelled by refraction along the top of the high speed zone just below the weathering layer.
