This video, courtesy of Karl Bester, is the demolition of a 14 story building in the inner city of Pretoria. The site has a higher education building on one side and a heritage church on the other. A NWNP geotextile was used extensively, both as shard capture at detonation points and to protect the university building but most impressively a short time before the blast a curtain of geotextile was raised by two mobile cranes to protect the adjacent church and its stained glass windows from damage. It took 3 seconds from first blast to total collapse into a mound of rubble – and the adjacent buildings suffered no damage. The blast curtain of geotextile retained rubble and spill, as evident at the toe of the curtain in particular. Watch the demolition.
