The workshop was constructed of a heavy-duty concrete block, with a block and beam ceiling and a concrete screed floor. The fire had burnt through a plastic tanking system which was fitted to the walls, this then created an oily soot residue over the entire workshop construction.
There had been an attempt to clean the workshop using a jet wash with a degreasing agent which failed to make any impact on the contamination. Concrete can be very difficult to remove fire and soot contamination from as the surface is mostly porous which allows the moisture and contamination waste to soak further in, actually causing more damage and debris than before.
On our initial visit we performed a test clean to several areas which allowed us to show potential results and to accurately quote for the full work. After the test clean was carried out a quote and report was sent from site and was authorised immediately. Work was then carried out over 2 full days of blasting with some great results to all areas.
Dry Ice blasting being non-abrasive meant there was very little debris to clear up after, making it a very efficient and effective method of decontamination which was then ready for reinstatement. The odour had also been eliminated meaning no further deodorising processes where required.
