Onyx Civils: Your Trusted Groundworks Partner in the South West
Onyx Civils is a family-run business with a passion for delivering exceptional groundworks and civil engineering solutions. We're based in Dorset and operate throughout the South of England, providing a comprehensive range of services to meet your project needs.
Our Story: From Humble Beginnings to a Leading Groundworks Contractor
Our founder, Rob Williams, has been involved in the construction industry since childhood. His passion for machinery and construction led him to pursue a career in heavy plant mechanics, gaining valuable experience working on various projects for local councils and Wessex Water. In 2012, Rob established himself as a sole trader, quickly building a reputation for quality and reliability. As demand grew, he formed Williams Plant, expanding his services and fleet of machinery. In 2016, Rob and his wife Fiona, who had always been a key part of the business, decided to form a limited company. With a dedicated team of experienced operators and ground workers, Williams Plant Dorset Ltd secured significant contracts as both a main and principal contractor. In 2020, the company was renamed Onyx Civils Limited, reflecting their commitment to excellence and the values they hold dear. Onyx, meaning 'claw' in Greek, also represents a rare precious stone symbolizing positivity, determination, stamina, perseverance, and courage – qualities that define Onyx Civils' approach to work.
