NORHAM was founded in 1989 by David E. Turner and his associates to supply the famous Flex-Seal coupling to meet requirements for joining sewerage and drainage pipes of both similar and different materials and sizes.  Since then, the NORHAM offering has undergone continuous growth, with new solutions for water supply and sewerage systems. Today, NORHAM is based in the town of Saint-Donat-sur-Herbasse in south-east France's Drôme department, where it pursues its development. The company recently took over the UK company Norham Plastics, a plastic injection specialist, and has also doubled the size of its French factory .

NORHAM is a people's company with a human face, a company that wants to be the “nice guy” while remaining totally professional. Our strong team spirit allows us to do just this, providing a welcome for our clients and partners that is as warm as it is serious. But NORHAM, as its logo suggests, is also a stronghold, a solid, lasting edifice that will always be there for you to count on. We take care to live up to this image with every step we take.
