Wayne Zakers - 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 David Ball 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.


Martin Coles - Group Financial Director


Martin joined David Ball Group in February 2016 as Head of Finance.

He trained as a Chartered Management Accountant and has worked in numerous sectors. In his early career these included engineering, capital goods distribution, hygiene rental and a government ‘quango’. He gained all round experience in financial management, planning & analysis and costing.

At the age of 34, in a quest to widen his experiences, Martin trained as a secondary school teacher. He taught A level and lectured on professional accountancy courses. He also took up the opportunity to be an author for two educational publishers.

Back in industry, Martin joined ID Data plc as financial controller, a stock exchange listed company, and was subsequently promoted to Finance Director. There were severe profitability and funding issues, but despite this, he had a major role in several business acquisitions. After this he was Finance Director at Sylmar Technology, and together with the MD completed a successful MBO at the height of the financial crisis.

Martin was attracted to DBG because it has the prospect of becoming much bigger – and it looks an enjoyable challenge to contribute towards achieving that goal.
