What types of excavators / diggers are used on demolition contracts?



Every demolition contract is slightly different and therefore different excavators / diggers will be needed—such as an industrial demolition contract will often need much larger excavators. Sometimes huge high-reach excavators will be needed, sometimes a mini-digger will be needed for internal demolition, so a wide range of excavators are often needed.

Therefore, the demolition company must carefully select suitable excavators, the use the correct size machine is important, and ensures that we safely demolish the building.

Whether the building is huge hotel or a house, we have the demolition excavators to demolish any type of building. We use Hitachi excavators, these are brilliant and powerful machines.

Once equipped with the right demolition attachments, we can demolish any type of building.


Commercial demolition

We have demolished a vast range of buildings, ranging from steel warehouses / factories through to houses. Therefore, we need to use a range of different excavators, ranging from 10-ton machines, up to 50-ton excavators.

Therefore, we use various excavators, whether the Cardiff demolition requires a huge building to be demolished, such as a large factory, a warehouse, or a light industrial unit- here at South Wales Demolition Ltd, we can safely demolish any building.

Therefore, the different types of machines we can use are:

– Kubota mini-diggers
– JCB 3CX machines
– Large 30 ton machines
– Crushers


Different demolition attachments

Depending on the demolition contract, different demolition attachments need to be used.

Therefore demolition companies use the following demolition attachments:

– 360 Rotar grabs
– Hydraulic hammers
– Steel shears
– Crusher buckets


High reach demolition

Sometimes, a building will be so tall that a demolition machine, called a “high-reach excavator”, will be needed. Made by companies such as Kobelco or Hitachi, and there are many other manufacturers as well, these machines are very powerful.

Fitted with a huge arm, they can reach the top of most buildings, helping to safely demolish the building.

Then once the concrete has hit the ground, often it’s in small pieces. If it’s not, then a smaller excavator will be needed, fitted with what’s called a hydraulic hammer; this will hit the concrete and break it into smaller pieces.

Then the concrete rubble can finally get fed through a jaw crusher, then the hardcore can stay on the demolition site, ready for the construction company to use it in the foundations of the new building.



Whether it’s an industrial, commercial, or domestic demolition contract, different jaw crushers will be suited to crushing certain different types of buildings.

Crushing has become massively popular with demolition contractors, and construction companies alike

The reason is the building can be crushed, and the hardcore can stay on the demolition site.

This way the hardcore can be used again when constructing the foundations of the new building.

Less lorries are therefore used to transport the stone waste away. Less diesel is also burnt, as less lorries are used, which is good for the environment.

If its a single house that’s being demolished in Wales, then a small crusher could be used. On a large industrial contact, a more larger crusher is often used.

For example, some crushers could easily exceed over 100 tonnes in weight; this might be a quarry crusher, for example, they could crush a massive amount of concrete, brick or stone per hour.

How much does it cost to demolish a building?

When offering a customer a demolition quote, it’s essential that we consider the following factors when offering a quote. Within this article, we will walk you through the thought process our estimators use when pricing demolition contracts throughout the United Kingdom.

Walk around the demolition site


Walking around the building due to be demolished is essential, we therefore often need to walk both outside and within the building.
The main reason is that the demolition estimator can determine which excavators are needed and roughly how many personnel will be required to demolish the building.

How many excavators will be needed?


When working out a price for that particular demolition contract, the estimator must determine how many excavators will be required. For example, on some demolition contracts, it will be apparent that only one demolition machine will be needed.
However, on another demolition contract, multiple excavators might need to be required to safely demolish the building.


How far the building is located from recycling facilities


If a building is relatively close to a place where the aggregates / waste can be recycled, then the cost of the demolition can be lower.

However, if there multiple tipper lorries needed, that is, the eight-wheeler trucks, and they need to drive some distance before they can arrive at the nearest recycling facility, the cost of the demolition will need to increase.

This is because additional diesel and driver time will be needed to transport all that waste, brick, stone and breeze blocks to the recycling facility.


Which building materials need to be recycled?


Some building materials are much cheaper to recycle than others. For example, if it’s a concrete roof tile, it is much cheaper to recycle that roof tile, than other types of roof tile.

On the other hand, if the roof tile is made of asbestos, a specialist asbestos removal firm will need to come in and remove the asbestos before any demolition work can start.

How long will demolition staff and equipment need to be on-site?


It’s then down to the estimator to work out roughly how long the demolition equipment, such as the excavators and the crushers, will need to be left on site.

If the demolition equipment is needed for a long period of time, then this will increase the cost of the demolition.

Also, the estimator needs to calculate how many staff are required, and how much this will cost in terms of labour costs.

Therefore, if there is a lot of what they call soft stripping, which is removing the plasterboard, timber, and plastics from the building, this will substantially increase the demolition costs.

If the job doesn’t need soft stripping, perhaps it’s already been gutted, or the building is fire-damaged. Therefore, soft stripping the building is not required because the contents of the building may have been burnt, so sometimes, it is cheaper to demolish these types of buildings, as theres less waste.

Steel buildings

It is often cheaper to demolish steel-framed buildings, that’s because steel can be widely recycled.
For example, items such as copper cables, which are nonferrous and ferrous metals, can be recycled very easily.

Large excavators, fitted with a sheer, can cut through the metal and place it into awaiting recycling bins to be easily recycled.

We specialise in demolishing steel buildings, such as large factories, warehouses, and retail buildings.
Often, these commercial buildings need giant excavators; that’s to safely pull the building to the floor. We have large machines capable of demolishing large steel factories, and other types of buildings.

Therefore, if you would like a demolition quote, why not call our Cardiff demolition company? South Wales Demolition Ltd has been providing good quality demolition services for a very long time. We can demolish anything from steel buildings to domestic buildings such as houses.
