Video: A Technique for Repairing Fire Damaged Concrete

RICHMOND — Atar Barkai : Today I wanted to discuss a special technique we using when we have projects with fire, smoke, and soot damage over concrete-type of material, versus the normal residential drywall and wood. In those cases, what we utilize is dry ice blasting. As you can see, the guys here using the compressor and the special machine are putting a lot of pressure on the concrete, using the dry ice blasting and removes all the residues of smoke and soot from the surfaces. If a company or contractor does not have the ability to use this method, what they will have to do is a wipe-down of the surfaces. What makes dry ice blasting much more superior and much more effective is that with that technique, you can actually penetrate all the small, little, porous areas and remove all residues. A simple wipe-down like the old days just wouldn’t work in these cases.
