The Company Today

Established in 1947, the company is justly proud of its heritage and continues in the traditions of its founder, the late Denis May. The name Denis May is recognised throughout Devon & Cornwall as one of the leading manufacturers of Concrete Blocks and Aggregates. They have developed their skill over the years and continue to pass this down through the generations of the May family. A true family business, with integrity and reliability at the heart of their commitment to not only meet their customers’ needs, but to exceed them.

From their two manufacturing facilities, one at St Stephen in Cornwall and the other at South Molton in Devon, they produce over 375,000 concrete blocks each week, and more recently the production of a range of sand and aggregates from their new location at Wheal Remfry. This sees Jack May, the son of Denis May, continuing to drive the expansion of this successful and progressive company.
