It's been 30 years or more since asbestos was used in the widespread construction of homes in this country. There are nevertheless quite a lot of properties still in existence that were built before the Second World War and were made with asbestos cement. Maybe you live in one of these properties and are considering some modifications? As you draw up your asbestos management plan, where are you likely to find these leftovers?
Firstly, you should bear in mind that although your home may not be from the World War II era, asbestos has only been banned on a nationwide basis since the end of 2003. So, you should be aware of the possibility of finding asbestos in one of those properties.
Two distinct types of material were once used on a widespread basis. The first type is known as non-friable or bonded, while the second is known as friable or loosely bound.
The Less Risky Type
The non-friable asbestos contains a certain amount of fibrous asbestos, which is embedded into the cement. These are considered to be less of a risk, as they are "retained" in the cement itself. Nevertheless, if you are thinking of drilling into cement products as part of your renovation work, you need to determine if they are likely to contain those fibres first. Once you penetrate the surface, fibres can be released into the air, and are as such a significant risk.
Consequently, be very careful when working with insulating board which is used for sound, fire or heat insulation. This is typically in place around the circuit boards and electrical panels, or in ceiling tiles.
When Extra Caution Is Needed
The other type, the "loosely bound" variety, is generally found more in industrial settings than any domestic house. Still, you should be wary when you are dealing with insulation around heaters and hot water systems. Also, if you are pulling up vinyl floor or linoleum you might find this here, or in use as lagging around your hot water pipes. If you suspect asbestos may be present here, you're better off calling in the experts.
Some other places to look for asbestos include within patterned sheeting on the roof, or around the edges of the chimney flues. It is known to have been included within cladding on the outside of the home, within weather boarding or even as a lining underneath the eaves in the attic.
As it is difficult to determine if asbestos is there just by looking at it, it's best to get an expert analysis. The very best way to be sure is to have it tested in an accredited laboratory.Share

Welcome to my blog. My name is Anita. I am an artist and a writer, but I like to create with any canvas that I have, and that includes my home. I see homes as almost blank slates that need special touches to make them shine. Over the years, I have received a lot of calls from friends. When my friends need to sell their homes or have them appraised, they call me for advice. I think I've helped a lot of them get higher evaluations than they would have otherwise, and I love advising them. If you want tips and ideas on getting great appraisals, this blog is for you.
