UKDS have recently undertaken a confined space entry beneath Hampton Court Palace in Surrey. The purpose of the survey was to determine the condition of the brick tudor structure and its lay. The structure was an old sewage outfall from and since demolished toilet block within the palace likely constructed around the reign of Henry 8th. Additionally a basic sonar scan was undertaken beneath the Jetty in front of the culvert to further peek into history. The overall condition of this 500 year old structure is a testament to the construction methods and materials used by the tudors.
