No residual waste
Contaminants such as grease, bitumen and certain paints can best be removed with dry-ice blasting. The dry-ice blasting process uses compressed air to accelerate frozen carbon dioxide (CO2), which, upon impact, creates a micro-thermal shock that breaks the bond between the contaminant and the substrate. The high pressure air stream then easily removes the dirt from the surface. Dry-ice blasting leaves no chemical residue as dry ice sublimates at room temperature. Therefore, only the removed material must be disposed of, making this a clean and neat process.
