The VorTech machine from Restorative Techniques has been used on a project featured on Channel 4’s Grand Designs program.
The VorTech machine cleaned the outside of this wonderful old building that is a grade 2 listed water tower in London.
VorTech is a 'swirl-abrasive' system, borne out of the "Jos" (pron. "Yoss") technology, originally developed in Germany, in the 1980's. The system uses a selected abrasive carried by a flow of compressed air to a nozzle, at which point, water is added. The mixture then passes through the nozzle and exits in a vortex, which is directed at the substrate to be cleaned.
