Castle & Pryor Ltd was established in 1991 by the two principal Directors, Mark Castle and Graham Pryor. Both Mark and Graham identified the market changes in technology and the development of new initiatives that the diamond drilling and cutting industry was offering.

They saw that this new development was exciting and clearly leading the way in technology, which was transforming the way the construction industry was working. This philosophy has continued to this day where the Directors are at the forefront of engaging with new technology and techniques to improve safety and efficiency in the diamond drilling, cutting and controlled demolition industries.

Through acquisition, Castle and Pryor Ltd moved into the Aviation sector, first working within the Airport Terminals but then leading to working on the stands, taxiways, and runways. To meet their clients’ needs they introduced new infrastructure services until were able to provide a full concrete pavement infrastructure package. They are now able to offer this package to other infrastructure sectors such as Highways, MOD Facilities and Docks/Terminals.
