Hi Tom and welcome to the forum, I once had to burn some ground bolts flush to a concrete drive, it went ok with only some heat scorching marks.

I was though burning at a 90 degree angle to the surface, it may make a difference if wet or dry...if wet the water may expand fast and blow some concrete away I suppose.

Thats just my 'I am not an expert' opinion...plenty of face and neck protection would be called for of course.

As Steve says it's the water within the concrete you need to be aware of. Plenty of PPE

Am I the only one here who reads that as 'can I cut concrete with oxy-acetylene?'

Thats what i thought Pete.....in which case, its a no....
