Shock waves from implosion demolition
Shock waves from implosion demolition
(OP)
My client plans on imploding a nine-storey building on the site we did geotechnical investigations for.
My concern is whether the shock waves generated by the implosion will or will not affect surrounding buildings (historic buildings). The underlying soils comprise of sand up to 8.0 metre thick underlain by competent rock (shale).
My thoughts are that since the water table is high (within 1.0 metre of existing ground surface) and that the imploded rubble will provide a 'cushion' for the shock wave, that the shock waves will not be a problem.
I would appreciate to know what experience has been had by others regarding implosion demolition and ground induced shock waves. I would appreciate your comments.

a few years back, i had to get a little blasting done next to (1000-1500'+ away on the other side of another small building) a well known disease research facility. after our initial blast to remove rock, we were informed that we had cracked a 5th floor 8-10" thick slab in a highly contagious research lab. they didn't how bad the cracks were because it would take a week to disinfect the lab for someone to go in and evaluate the floor. as you can imagine, it didn't pan out quite like the people had claimed. as i'm sure you are well aware, i suggest that you cover every angle possible when dealing with blasting and people looking to make a claim of "damage". good luck.

You might want to take a whole pile of pre-demolition photographs for comparison of damage.
