Please be patient while photo loads Building: Kantoorgebouw de Rijswijk
City: Rijswijk, Holland
Date & Time: September 25, 2000 - 11:00 am
Implosion Contractor: Jowenko Aannemingsbedrijf Uittenboogaard
General Contractor: Van Vliet Sloopwerken
Height: 8 stories

While we don't often hear about them, there are plenty of implosions happening in Europe. This 8 story building in Rijswijk, Holland was one of the more interesting ones. It is common to see a building collapse first in the middle, then to have the two end walls fall towards the center. What makes this one unusual, is that it collapses at two different points, each about a third of the way in from each end. Then the two ends and the middle all fall into these voids.

Another noteworthy aspect of this implosion is the detonating system used. For the first time in a European building, electronic detonating caps were used. Each one of these blasting caps contains a tiny microchip, which can be programmed at the job site to go off at a precise time. This allows for very precise control of the firing delays during the implosion. On this job, it was very successful. Only time will tell if this becomes a more common method of wiring charges in a building.

Many thanks go to Francis Hermans of Brussels, Belgium for sharing these great photos with us.

Location: Cameroon
Blaster: Francis Hermans

Until now, all of the blasting photos on this site has been of land-based structures. But a lot of explosive demolition work also occurs at sea. These photos are of the severing of a wellhead near Cameroon by Belgian blaster Francis Hermans.

In the early morning hours on February 23, 1994, an enormous sinkhole opened up at the base of this downtown office building. Throughout the day, the sinkhole enlarge, causing the building to sag farther, and portions to collapse. Implosion was determined to be the safest method to bring down the unstable building.

    This is the beginning of a catalog of implosions that have occured in my local area (and other areas) over the years. We were not lucky enough to attend them, as most of them happened before we got into this interesting hobby. For the ones that we have been to click here.

    We would like to thank Brent Blanchard of Protec Documentation Services for loaning the site these photos of RCA, Phoenixville, Sears and Mayfair from their archives.
