Coleman Tunnelling's late founding member, John Coleman, is considered to have been a pioneer of trenchless technology and was a founding member of the Pipe Jacking Association, originally established in the UK. Under his leadership the company expanded its market base over several decades, undertaking projects throughout Europe, Asia and Africa.
As economies of scale tighten within the construction industry, clients are leaning toward cutting costs wherever they can. Group Five Pipes' long-term success rate on two of its corrosion coatings - polyurethane and BituGuard - ensures the longevity of its steel pipes is increased; further contributing to sustainable infrastructure.
