    Re: Soda Blasting For Mold Removal

    Posted by RemDude on 6/05/06

    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

    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.
