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.

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.
