There is a lot more to demolition than meets the eye and although we certainly couldn’t fit everything in one blog post, here are a few pointers to get you in the right direction if you are thinking about demolishing.
1. It’s likely your house contains asbestos: Although the health risks associated with asbestos are well known, most homeowners are unaware of just how widely used asbestos was in Australia. If your house was built or renovated before 1991 then there is a high chance it contains asbestos in one form or another. Asbestos is commonly found underneath tiles, in splash-backs, around fire places, in walls and in the roof as insulation.
2. Residential demolition is carried out by excavators: A common misconception held by a lot of people is that all demolition is carried out by explosives. This may be true of bigger structures, where an explosion technique called ‘implosion demolition’ is used’, but for houses an excavator is more than powerful enough to get the job done. Performing demolitions works with excavators is known as mechanical demolition. This type of demolition is safe and relatively quick; however, it does mean that in order to perform demolition works your property needs to be accessible by our excavator and float truck.
3. Asbestos isn’t the only dangerous substance that could be lurking in your home: That’s right, other dangerous materials like lead paint or lead dust could also be present in your home. In some cases these toxins will need to be removed before demolition can begin. Something else to consider is that before the excavators can roll on in any air conditioners on the property need to be degassed. This prevents dangerous R22 and R4 gases escaping into the atmosphere and damaging the ozone layer. It is also required by Australian law.
4. Development Approval (known as DA) is needed : Ok, so this one is a little bit complicated, but basically you need permission from your local council before you can go ahead with any demolition works. This can either be obtained directly through your local council or through a third party certifier, which can be arranged by your demolition company.
5. Salvaging building materials can help to subsidise the cost of your demolition: Although there is unfortunately always some waste associated with demolition, a large amount of building materials can be salvaged from a demolished structure. In particular bricks are easy to salvage and are in high demand, fetching just under a dollar each at a recycled brickyard. Not only is recycling your demolished home good for the environment, the revenue gained from selling salvaged materials can help to reduce the total cost of your demolition.
