How Rainbow International helped a school continue with Injection Drying.
All properties can suffer water damage and most do during their lifetime. When it happens in a school it creates new issues such as how can we continue to teach our students and rectify the damage? Injection Drying is your answer.
At this particular school, many classrooms have suffered water damage and most of the contamination had been trapped within the wall structures. The builders and insurance company wanted the school to remain open and for us to dry the affected areas in a set sequence.
The sequencing was to allow the school to remain open and at the same time rectify the issues the water had caused – we are able to achieve this with Injection Drying
We offered to dry the cavity walls with injection dryers. The process would allow the planned operation of dealing with the drying and ensuring that the school could remain open.
What is your Injection Drying process?
In case you are wondering how can you tell if the area in a cavity is dry or not without taking a reading from the structure or damaging the wall, this is how we diagnose:
- Gather relative humidity readings from an unaffected area.
- Take Grammes per Kilogram readings from the air in the unaffected area.
- Measure temperature readings from the unaffected area.
Use this information to set a drying goal. Once we have ascertained the wet cavities, which will be confirmed with a reading above those taken in an unaffected area, you can now install the injection drying equipment. The only damage to the structure is a line of small holes into the voids. Holes are normally drilled behind the skirting boards which would need to be removed. You now monitor on a regular basis testing the air that is venting from the drilled holes for RH, GPK and Temp. Once they are the same or below the test site you used to set drying goals you can safely assume that areas within the voids are dry. Once you feel that the goals have been reached or exceeded turn off all equipment leave the areas for 72 hours to allow for an equilibrium to form. Then test again. If all goals are achieved it is at this point you can remove the drying equipment.
Rainbow International technicians are trained to use injection dryers in both domestic and commercial properties.
