Systemastic have provided mastic sealant services for several civic works across the UK. These include a water treatment plants, sewage treatment plants, refineries, bridges, transport infrastructure a nuclear power stations. Often civic works will require sealant applicator mastics and methods which our staff have been trained in their use and application, for example preventing passage of media (air, water, chemicals, smoke) within the confines buildings.

A significant number of our civil projects have been undertaken in conjunction with I.D. Corran. We have worked with them decommissioning nuclear plants such as Bradwell where the requirement was to seal joints to help preserve the structure for a century.
