Asbestos Survey in Harpenden

Are you planning to remove or renovate your garage? Before proceeding with the intended project, it’s usually essential to firstly determine whether or not your garage contains asbestos. However, asbestos isn’t the easiest material to identify and even more so when you’re unsure of what it looks. The fibres on the other hand are not visible to the eye and can’t be smelt as it’s odourless. In this article, we’ll provide you some helpful tips to spot an asbestos garage roof. Let’s take a closer look!

✓ Figure out when the building was constructed. In the year 1999, a ban was placed on the use of asbestos in the UK, both to manufacture and supply of asbestos materials. As a result, if your garage was built before this period, then it’s very likely that an asbestos containing material was used. It’s also important to note that several garage roofs that contain asbestos are constructed with the help of flat or corrugated sheets of cement.

✓ Check the surface. When cement contains asbestos its usually fairly thin with visible fibres running through it. Also, the surface of the cement will have a texture and also some craters. If you an older cement sheets is incorporated, there’s a high chance that it contains asbestos.

✓ How it’s built. Asbestos materials are usually joined together by aluminium runners and help in position with nails that are blunt-ended. Take a look at the joints, if the sheets inside is held together by wooden or plastic runners then there’s danger.

Finally, roofs made from asbestos cement has a good chance of becoming very brittle.

If your house is built before the 1980’s it’s likely to contain some form of asbestos material which when disturbed can release some harmful fibres whose inhalation can lead to a number of fatal diseases and health issues like lung cancer and asbestosis. If you suspect that your house contains some asbestos materials, the best step to take is to call in a qualified asbestos consultant to carry out a thorough inspection of the area so as to identify the potential asbestos containing materials in your property.

The result of the testing done will bring a peace of mind as it’ll confirm whether or not the material actually contains asbestos. In the event whereby the testing result shows that the material does not contain asbestos, this will significantly reduce your renovation or demolition cost. So if you’re wondering how asbestos testing can be done, simply continue reading.

Identifying asbestos is as simple as just looking at the material with the naked to check if it contains the harmful substance. The presence or otherwise of a potential asbestos containing material can only be confirmed by laboratory testing. A qualitative identification of asbestos in a bulk sample is the best method for testing for asbestos. This asbestos testing process involves taking a look at the fibres under a polarized light microscope and under varying conditions to determine the kind of asbestos it is, if present. The result of the testing, if positive, will identify the type of the asbestos discovered and this can be either white or chyrsotile asbestos, brown or amosite asbestos or, blue or crocidolite asbestos. However in the event whereby the sample doesn’t contain any asbestos, the test result will show NAD or No Asbestos Detected.

In recent times, when about to purchase or renovate a building that was constructed before the 1980’s, most homeowners will be particular about knowing whether or not asbestos containing materials are present. Also when a property is being checked, a lot of individuals would want to know the peak years for asbestos to be used in homes.

Modern asbestos production started in the 1800s during the time of industrial revolution, but after some regulation were made to ban some asbestos products and uses in the late 1970’s, the production witnessed a significant drop. The United States was the foremost users of asbestos according to the USGS but this lasted until the 1960’s when it was overtaken by the Soviet Union. In this article, we’ll look at the years of use for asbestos containing materials like pipe insulation, vermiculite as well as wall systems.

✓ Insulation. Asbestos insulation was commonly used in homes with lots of focus on both piping and ductwork. This was started in the year 1908 but was ended between 1915 and 1920 by Air-Cell pipe insulation.

✓ Vermiculite. This refers to a mineral that’s popular for its insulating properties and mostly used as insulation for attics. It possesses a gold to brown kind of appearance and it’s also a pebble material that shimmers in the light. According to the EPA, if this material is suspected in a home it should be assumed to contain asbestos.

✓ Wall Systems. Plaster and drywall are very common wall types that are asbestos containing. And until asbestos was banned both wall systems are said to have asbestos. For example the drywall sheets as well as it’s joint compound both features asbestos from the 1930s to the 1980s.

By now, every homeower should be fully aware of the dangers of asbestos due to the fact that it can be found in a wide range of building products from the roofs and walls and right down to the floor tiles. An exposure to asbestos especially when disturbed can be life threatening as it can lead to a plethora of health issues which includes lung cancer, mesothelioma, asbestosis and lots more.

Asbestos are more dangerous when damaged or disturbed, but if they’re found in a great shape and are left undisturbed, then asbestos containing materials poses little to no threats. This dangerous material can be found in a large variety of insulation. And when compared to batt insulation, loose-fill insulation can be highly dangerous when it’s not installed in the right way. When poorly done, several particles of the asbestos can be released inside the wall or around pipes. As a result, insulation becomes a big worry that most homeowers will face down the road.

Homes that were constructed before the 1980’s commonly features steam pipes, hot water pipes as well as furnace ducts insulated with asbestos containing materials. And this is primarily because there’s no other fire retardant, thermal as well as acoustic insulator like asbestos that’s as effective and affordable as it is. However to really know if your building’s insulation is made with asbestos containing materials, you can take the following steps:

✓ Find out when your house was built. If it was constructed or renovated before the 1980’s then it’s likely to contain some asbestos materials.

✓ Although this is not advisable, but if you plan on checking the insulation by yourself, you should ensure to put on protect equipment such as goggles, gloves, masks and a safety suit.

✓ Check for insulation available in the building. The asbestos containing insulation in both batt and loose-fill types are grey-coloured so this shouldn’t be too hard to spot.

✓ Examine the pipe coverings especially the blanket type and cardboard coverings.
