Mold Problems Photo Album: Cordillera, CO - Environmentally friendly Cryoclean Dry Ice Blasting Technology to Remove Microbial Growth
We identified the cause of microbial growth to the wooden structural elements of this crawlspace to be a plumbing leak that over time, created the perfect conditions conducive to microbial growth. In order to protect the house and its occupants from airbourne contaminants, we layed down floor protector from the entry to the crawlspace access, installed a containment around the crawlspace access, installed airscubbing devices and negative air, and employed proper donning and dothing of our PPE during remediation. After a thorough evaluation of the subfloor the fiberglass insulation was removed, bagged, and disposed of properly. After using the CO2 cleaning method, we applied an EPA Registered white fungicidal coating to all wooden structural elements to prevent future microbial growth. Once the fungicidal coating was dry, we did a light regrade of the Earth floor in preparation for the CleanSpace Encapsulation System. Next, we rolled out Drainage Matting that allows moisture and air to flow freely underneath the liner as a passive radon system. We then installed 2" foamboard and closed cell spray foam on the perimeter exterior walls and rim assembly to keep the crawlspace insulated. This allows the subfloor to be accessible for plumbing and electrical maintenance. Lastly, we installed the 20 mil, antimicrobial CleanSpace liner over the drainage matting and foundation walls to help prevent moisture, mold, & Radon from re-entering the crawlspace.
Mold Remediation Protocol
Our protocol for mold remediation reflects the highest standards of procedures in the industry to protect our workers, the structure, and occupants. This includes IICRC Certified Applied Microbial Remediation Technicians, proper PPE and direct air supply, floor protection, containment with zipper door access, HEPA air scrubbers, negative air, and sufficient lighting to perform the mold remediation.
Subfloor Fiberglass Batt Insulation Removal
We must 1st remove and bag the fiberglass batt insulation throughout the crawlspace to gain access to the wooden structural elements affected with surface mold. The opening of each bag is twisted closed, folded over onto itself, and sealed with tape. The last step is to wipe down the outside of the bags prior to transportation through the house to the nearest exit to be hauled off and disposed of.
Dry Ice - CryoBlast - In progress
The idea is simple - dry ice pellets are accelerated in a pressurized air stream and directed at the subfloor, joists, beams, piers, and sill plates to physically remove the surface mold.
