Wayne Zakers

Group CEO

Wayne joined the Group as CEO in June 2016.

A Chemical Engineer by background, he started his career with the chemicals arm of a multi-national oil and gas company. His early career was spent in operations management and engineering, and led to Chartered Engineer status. He worked in financial, commercial and procurement roles, his last role being business manager for a portfolio of solvents businesses.

A desire to develop his career in a different environment and with new challenges led him to move to a premium supplier of construction chemicals. His role grew from General Manager to Vice President level in Sales & Marketing, and in running the international export team, selling into four continents. Before joining David Ball Group Wayne spent four years as VP Europe, including manufacturing operations in Denmark, Spain and the United Kingdom.

When approached about the CEO role at DB Group, Wayne was struck by the enthusiasm and passion of the team, as well as the support and long-term commitment of the shareholders. The high service levels offered in the waterproofing business, based around the famous PUDLO brand, stood out and were highly valued by the customer base. The ability to significantly reduce the environmental impacts of the construction industry through the Cemfree technology was an important factor in Wayne’s decision to join the company.
