Read the latest magazine Flat Roofing Industry News Single Ply Sole UK Distributor of Alwitra Marks 40 Years of Expert Flat Roofing 5 March 2025 ICB HAS come a long way in the past 40 years – and their achievements are worth celebrating. Lots of things were happening back in 1985—the first mobile phone calls were made in the UK, Sir Clive Sinclair launched his Sinclair C5 battery-operated tricycle, Eastenders graced our screens for the first time, Everton won the European Cup, and Live Aid ruled the world for fundraising. More notably, a small single ply roofing operation started up in Poole, Dorset. 41 years ago, in 1984, Michael Steinbach worked as an export manager for the German roofing company Alwitra, a renowned superior, long-lasting waterproofing membranes manufacturer. Visiting England for the first time, he arrived in Poole, Dorset, to review ‘project number 1’, for IBM near Winchester. During his stay, he realised the potential for his company’s products in the UK. International Construction Bureau’s first offices, with founder, Michael Steinbach, second left. Alwitra agreed that Michael could be the sole provider of their membranes in the UK. The following year, on 28 March 1985, ‘International Construction Bureau’ was born. ICB began to beat the competition and win more work, one project at a time, allowing the company to move out of operating in Michael’s house and secure its own premises in Bournemouth. It then expanded into five more units before moving to its current HQ in Poole. 40 Years of Expert Flat Roofing Today, the ‘International Construction Bureau’ is ICB Group, with CEO Rob Jackson at the helm, providing an enviable suite of solutions for the construction industry, backed by the assurance of full ISO accreditation for quality, environment and health & safety.
