I've done that before. Not 55' but about a total of 10'. I used a diamond blade; it cut like butter. I didn't use water, however.
I apologize for any confusion on my part. Ignore the 55' measurement -- I mainly included it for *perspective* regarding this ridiculous piece of concrete. I mean....what does someone do with a 55' x 6' concrete slab in the middle of a fenced backyard? What could someone having been thinking when they poured it?Your first statement sounds like you want to cut down the middle of the 55', but then you say across the 6'.....
I should clarify that HD ad, as they make it sound like each piece is $4.87, they come as a set of two for that price.Well, maybe I should re-consider.....
Both ddawg and canarywood advocate the "water-jet tunnel-under" approach. While I do eventually want to get rid of that slab little by little, it is certainly not essential to do so right now. The needs of the current task would be met by either a sufficient tunnel or a break in the slab. I will give this some further consideration.
Thanks to all for the helpful replies.
You don't necessarily cut one tunnel of sufficient size when jetting in multiple pipes. Depending on your soil type, cutting multiple smaller holes may be quicker/easier than one larger one.The needs of the current task would be met by either a sufficient tunnel or a break in the slab.
There indeed are shuffleboard markings on the pad, although i do not know if such was the original intention. Regardless, the slab is too cracked at this time to allow for decent shuffleboard play.I wonder if maybe somebody was going to put in a backyard shuffleboard court? It's about the right dimensions.
