Geotechnical testing specialist Geolabs has updated its colour chart classification tool in a bid to improve sample logging and add consistency to soil descriptions.
The tool was first developed several years ago by Geolabs director of training and innovation Chris Wallace to ensure all the company’s laboratory staff described the colours of soil materials in a uniformed way.
The chart has been updated and made suitable for the wider industry to use on site by printing it onto a plastic sheet.
Colours displayed on the sheet were based on the suggested values given in David Norbury’s Soil and Rock Description in Engineering Practice book.
Geolabs director John Masters said: “Due to the success of the card version of the colour chart we were requested to provide a more robust, weather-proof version for use in all weathers and locations. The latest version has been very well received so far and is a valuable addition to the suite of training tools that we are providing for all practitioners in the geotechnical and site investigation fraternity.”
