GKN Imtech Inviron gutter lining

The stoppage of leaks and improvement of gutters at this busy production centre.

Sector: Manufacturing

Roof Type: Valley and boundary wall gutters

Service: Gutter lining

What was the job?

Imtech Inviron at GKN Bristol’s main production facilities need to have a clean environment for their production. Numerous leaks from their gutters were causing production and safety issues.

TRS was contracted to provide purpose-made and engineered gutter liners that could be installed with the minimum of disruption and in the quickest possible time. Our teams installed an Ampteam Unifold gutter lining system to an excess of 2,000m of valley and boundary wall gutters across a number of roof areas. This system holds an exceptional life span (in excess of 50 years) and is guaranteed not to leak, despite the traditionally unpredictable British weather.

The result was leak-free gutters and complete peace of mind – thanks to the long warranty period and cost-effective solution quickly installed by TRS roofing contractors, GKN Imtech Inviron’s production could safely continue without disruption.


Stop multiple heavy leaks that were occurring across the site; keep costs low by lining existing gutters.


Keeping the building operational while carrying out work safely on fragile roofs. Maintain gutter capacity and rainwater discharge rates.


Leak-free gutters with a long warranty period. Costs were kept low and to budget.
