Dale Dempsey has had an interest in Hill Figures since the 70's when he started working as a Materials Engineer in the quarrying industry for Tilcon in North Yorkshire.
He was also involved with the testing and quality control of a wide range of lime-based products from Tilcon's main laboratories (then) at Lingerfield, near Knaresborough.
Tilcon were often approached by heritage groups to supply lime for a variety of projects.
Dale was able to draw from this knowledge and from the experience gained from running a successful 'Colour Corrective Company' for over thirty years to produce a range of products for restoring Hill Figure Carvings.
