UV light-curing technology is generally understood as a process in which a chemical curing process is triggered using UV radiation. The patented Brandenburger pipe lining process is based on this UV light-curing technology. In order to cure the liner, a UV light chain meeting the specific requirements is pulled through the liner which is already installed in the old pipe and erected by pressurised air. The resin contained in the liner material reacts to the UV radiation and cures completely within the briefest time.
