Re: Soda Blasting For Mold Removal

More | Report Post

I am just completed a remediaiton project which is the aftermath
of a soda blasting procedure. This is a 2,000 sq. ft crawl space
that was a Condition 3 site. The home owner had a remediaiton
company come in and soda blast followed by a white glove cleaning
with a well known quat disinfectant. They paid big bucks and the
project took several days to complete.

That was two months ago. The crawl space is back to Condition 3
because the remediator spread contamination throughout the
structure and did nothing to solve the moisture intrusion problem.
We used a chemical remediaiton process followed by the application
of an inhibitor followed by a dehumidification system. We were in
and out in less than a day and we were cheaper including the
dehumidification system and we have guaranteed our results for 5
years.

We have been called out to several remediation projects where soda
blasting has been used. Lift samples show re-contamination of
surfaces within weeks of blasting. It is apparent that this method
is aerosolizing spores and/or driving spores deeply into porous
surfaces where they remain dormant waiting for optimal growing
conditions once again.

From what we have experienced in the field, this is not an
effective remediaiton technique.
