High Rise / Tower Blocks
High rise tower block demolition carried out by the use of explosives gives a minimal period of disruption. The use of high reach mechanical demolition machines requires a large exclusion zone to be kept clear of people and vehicles for prolonged periods. The disruption this causes in city centres and congested urban areas is often unacceptable.
The area required for both the building to collapse into and the exclusion zone required around the building can easily be contained within an area so small that many people are nothing short of amazed. If you have doubts about explosive demolition being the right method for your project, contact us and we will be pleased to advise you on this often contentious issue.
PDC have to our credit the accolade of being the first company in the world to utilise electronic detonation systemss on high rise demolition. This detonation system allows accuracy never previously seen in the demolition industry.
Power Stations / Steel Producing Plants / Chemical Plants
The use of explosives on chemical plants has proven most effective and to be the safest way of undertaking the demolition of tall structures such as chimneys, flare stacks and process columns.
The demolition of concrete structures is well understood by most and it is readily accepted that these are suitable for being demolished by the controlled use of explosives. We at PDC regularly undertake the demolition of steel structures also. This can be done by the use of kicking charges and by the use of linear shaped cutting charges. Both of these method are proven successful.
One common myth is that explosive demolition throws debris for 'Miles in all directions'. With properly planed demolitions this is quite simply not true. Nearly all the demolitions we carry out have nearby retained buildings, plant or infrastructure equipment.
Our charges are selected and applied so as to ensure that as much of the explosives energy as possible it used to do the job required and as little as possible is wasted as 'air blast' and noise. In addition to this we use protective materials around the explosives to contain any debris that may be otherwise projected. Localised protection can of course also be used to give extra confidence that particularly vulnerable things like glass fronted buildings or operational plant remain unaffected.
Mining / Gas Works
Explosive demolition is most commonly used ongas holders. PDC have more experience with these than any other contractor in world.
To demolish these massive structures other means gives rise to considerable danger.
Using explosive cutting charges to sever steel work minimises the need for personnel to work at height. In addition to this our methods reduce the risks of fire and the exposure of people to toxic substances that are often present on such structures.
Savings in time and cost made compared to alternative methods of demolition.
Broadcast / Bridges / Industrial Chimneys
Industrial chimneys are generally constructed from reinforced concrete, steel or masonry.
PDC have developed specific methods for demolishing these different chimney types which takes account of the way they each behave when felled.
