DDS Demolition has a wealth of experience in explosive demolition. Our team are experts in controlled demolition, having carried out a variety of projects for a wide range of commercial, industrial, and even residential clients in the UK.
What is explosive demolition?
Occasionally referred to as implosion, explosive demolition involves strategically demolishing a building using controlled explosions. There are several different ways that this can happen to a building: falling like a tree, or falling into its own footprint.
How does explosive demolition work?
Thanks to careful placement by demolition experts of the explosives around the structural supports, the building collapses in on itself, or falls into a safe area, within seconds. It’s a technique best used on large structures, where using manual demolition with machinery and manpower would take a great deal longer.
If traditional methods aren’t viable for your project, please get in touch with DDS Demolition.
What’s the process for the demolition of a structure?
Before explosive demolition can take place, a series of steps must be taken to ensure safety as well as success:
A full and thorough survey should take place before anything else, to assess the materials used in construction, as flammable, toxic or otherwise hazardous materials will need to be flagged, and could affect the demolition process.
The design of the building, the building codes involved, and the surrounding area should also be taken into consideration, in order to anticipate noise, dust and disruption during demolition.
Removal of hazardous material
Anything that has been flagged as hazardous, such as asbestos, will need to be removed by specialist contractors prior to a controlled demolition, so this should take place as a priority.
Preparation and planning
Any building demolition should be meticulously planned, from the methods used to the sequence of explosions. Within this plan should be a full assessment of proximity to nearby houses, schools, hospitals and roads, with health and safety management procedures detailed for before, during and after the demolition.
It perhaps goes without saying that safety measures need to be followed to the letter by everyone involved in a demolition. This includes on-site staff attending all safety briefings, erecting and adhering to signs as well as wearing the appropriate PPE, and local areas affected by the demolition closed off as necessary.
How are the public notified of explosive demolition?
The local authority must be notified of an explosive demolition no later than 6 weeks before it’s due to take place. Residents in the area will then be notified of the intended date and time of the demolition, and any roads affected by dust and debris will be closed for public safety.
What methods of explosive demolition does DDS Demolition use?
Explosives placed around the main building supports and detonated in a sequence forces the entire structure to fall in a controlled way. The way it comes down falls into two categories:
Falling into its footprint
This is what resembles an ‘implosion’, where the building collapses in on itself to minimise disruption to the area around it.
Falling like a tree
Much like a felled tree, this method of commercial demolition makes the structure fall sideways into a large, free area. This works by placing explosives up one side, forcing it to fall in the opposite direction.
What are the advantages of explosive demolition?
Unlike wrecking balls, sledgehammers and excavation equipment, explosions allow a demolition to be orchestrated in detail, with a small window of time in which safety procedures can be strictly followed.
Demolitions can be over in seconds, with the site clean up done in one go, saving hours of manpower.
What structures can be demolished with explosive demolition?
Buildings - such as houses and shops
Industrial structures - such as offices and factories
Nuclear facilities and power stations
Explosive demolition projects
Power stations are some of the most impressive demolitions to watch, and a fantastic example of the speed and efficacy of controlled explosion methods.
Richmond Power station is one such demonstration of how DDS Demolition Contractors plan and execute a demolition, with the redundant power station, ancillary structures, cooling towers and chimney included in the project.

Why choose DDS for your explosive demolition?
Born in 1977, DDS has become a contractor of choice in the south east’s demolition industry through a reputation for not only carrying out safe and effective demolitions on a wide range of structures, but being an honest, family-run business too. 40 years of experience has given us the know-how and the confidence to undertake demolitions on complex structures in challenging locations, with a client base that rely on us for unmatched demolition services.
The size, location and building materials are all contributing factors in the amount of explosives required to bring a structure to the ground. There’s no one-size-fits-all policy when it comes to demolition!
The time taken to plan, execute and clear the site of a demolition depends on the size and complexity of the structure itself. While it can seem like an explosive demolition takes seconds to do, the planning and preparation can take months.
At DDS, we take every care to ensure that environmental legislation is followed, as well as remaining mindful of the local ecology - such as planning the demolition of Richborough Power Station around bird migrations. Hazardous materials are safely removed prior to demolition, and a ‘soft strip’ carried out, whereby all but the essential shell of the building is removed safely too, which includes fixtures, fitting and combustible materials to minimise dust.
Explosive demolition relies on a series of explosions in sequence to demolish the building, whereas regular demolition sees a team head in with tools and machinery that manually chips away at the structure.
Explosive demolition is better suited to structures that aren’t surrounded by other infrastructure, such as residential communities, but that’s not to say it’s impossible - DDS will always assess on a case-by-case basis.
