Tobermore Concrete
Tobermore began in 1942 as a sand and gravel pit started by two Henderson brothers in the Magherafelt area. After the war, their brother Sam - a D-Day veteran - came home from France and put his savings into it. They moved into precast concrete products for the local trade in the 1950s, and in the late 1970s became one of the first firms on the island making block paving, marketed as 'Pavia'. David Henderson joined in 1976, took over as managing director in 1987, and pushed the company into the British market. It is now one of the largest paving and walling manufacturers in the UK and Ireland, and it is still based at the edge of the same Derry village.
