Mechanical Demolition: An overview

When we tell people that we are in the demolitions business, one of the questions we are frequently asked - well, apart from ‘how much will it cost to demolish my home?’ - is 'oh, so does that mean you use explosives?’.

As much as we wish that our 9 to 5 involved chucking sticks of lit dynamite around like some sort of crazed miner from the wild west, this is not the case.

Demolition using explosives - a technique called building implosion which refers to the way the demolished structure collapses in on itself -  is generally used for larger structures like smokestacks, stadiums and skyscrapers.

This technique involves strategically placing numerous small explosives around the building so that the explosion occurs in a controlled manner. Although the actual ‘demolition’ is quick, preparing the condemned structure for building implosion can be extremely time consuming, with larger structures can taking as long as six months to prepare.

 Geez, calm down Neil, we know 'building implosion' isn't an actual 'implosion'.

In short, implosion demolition is simply not suitable or feasible for residential demolition. Plus, even if it was, chances are your neighbours might not be too happy with us blowing stuff up right outside their window!

Home Demolitions conducts all of its demolition work using excavators in a method known as mechanical demolition.

The term mechanical demolition refers to any demolition work that uses powered mobile plant (such as excavators, cranes, loaders and bulldozers). It can also involve a mix of hand demolition and mechanical demolitions techniques. The latter is true of how Home Demolitions performs demolition works.

During structural demolition - this refers to the demolition of the actual structure that occurs once any asbestos, roof tiles and salvageable fittings have been removed - machinery is used in addition to a labourer. 

Structural demolition of a residential property usually involves two people: an excavator operator and a labourer. The excavator operator systematically knocks down the structure while the labourer removes rubble and debris out of the way and sprays down the site with water to avoid dust clouds polluting the air.

When performed by a skilled operator structural demolition is quick, efficient and relatively tidy. The operator works methodically, systematically destroying one section of the house at a time and removing recyclable materials like bricks as they go.
