How Do We Remove Failed Insulation?
Following an initial inspection, if defects are found, a team will arrive on site and following their risk assessments will proceed to drill out the property. It will be drilled in a specialist pattern using original holes where possible. It will be necessary to open up vents and remove bricks at designated spots just above damp course level to allow exit points for the insulation to be removed.
Through the holes that are drilled, the operatives will drive compressed air through a rubber agitating whip and directional nozzle to break up and move the material to the exit points opened up.
An industrial vacuum then collects the material from the exit points and the operatives will work in a set pattern to move through the cavity ensuring that the material is removed.
The bricks are then replaced or vents installed, depending on customer requirements.
