John Kelly, Senior partner of CJ Kelly International, established the family run company in 1990 as an independent structural engineering consultant in the area of buildings and structural repairs using specially designed environmentally friendly products. It was not surprising therefore that the use of such products in the building and construction sector soon brought the company into the sphere of pipeline renovation. In 1995 CJ Kelly International became the UK technical representative for MC Building Chemicals sewer renovation systems from Germany. This was followed in 1998 with the company taking on a similar role for specialist pipe lining manufacturer, German-based KOB, in respect of the Brawoliner®system. Since then CJ Kelly International has successfully promoted both companies and their products extensively across the UK and now works with most of the UK’s major pipeline renovation contractors as an independent specialist sewer renovation consultant, concentrating mainly on trenchless techniques and environmental issues. CJ Kelly Associates was also integral to the development of the well-known Patch Box™ localised repair system alongside Ant Hire Ltd, which currently markets the system across the UK.

With this wealth of experience C J Kelly International can offer our customers with design and static calculations for any drainage and pipeline project, along with recommendations for the correct product for any repair. In addition we can oversee the project to ensure all installations reach the highest of standards.
