Is there any special tricks in using Tapcons on hollow concrete block walls?
I want to secure copper pipes, PVC drain pipes etc... onto my block walls using those copper straps. I am using 1-1/2" Tapcon screws and drilled a hole then when I feed in the screws it reached bottom and spins. The straps are still secured in that I can't pull them out, but I would prefer I can drive the screws in and be tight and snug.
The block walls are built with the typical 8" thick hollow blocks with a web in the middle. I think if I drill into the solid part of the block it's better but most times this is not practical as the pipe may be a vertical run from floor to ceiling and I want to secure it in say three spots and they are all in the thin part of the blocks.
Is there a trick? Will a specific size and length work best, reading the Tapcon website it says it needs a minimum embedding depth of 1" to a maximum of 1-3/4". It looks like the blocks are about 1" thick. When I drill them sometimes it punches through and sometimes it does not. I am just not doing something right so I stopped before I drilled too many holes.
Thanks in advance for any suggestions.
