Soak a towel to put between the wall and a piece metal like a cookie sheet.,,,,or slit a "tin can" open and use that.
Keeps the concrete from blowing up in your face from the heat.
The solder should flow all around the joint once youre able to get some heat maintained on it
If the Popping Concrete or Solder Flow is not what's giving you probs,,,add some more specific details to your question

Charlie has the right idea. Cut the pipe on either side of the wall, and slide a piece of PEX type tubing inside the old copper pipe. They make conversion fittings that require no tools [one brand is called 'Sharkbite'] so you can leave the original copper on both sides of the wall. You can also use soft copper if you choose. Do not use the TV gimmicks, they are a temp fix if they work at all. As soon as there is pressure inside the pipe, the sprays will fail. If it is a concrete or block/brick wall, moisture seeping inside can freeze and will break the bricks, creating a whole new problem.

i assume that the wall is "stealing" your heat......if this is the case, you really only have two options
1) go to the other side of the wall (i bet this means dig up the pipe) and cut out about 3' of pipe. cut and fit all the joints that you cant get to to solder. use a scratch awl to make lines on the joints so that your elbows can be re aligned. take the assembly apart and lay it out on the floor or where ever you can solder it. sweat the assembly together on the floor and put the finished assembly back through the hole in the wall. now all you have to do is sweat a couple couplings.
2) get a compression fitting and use it at the wall (dont use dope or Teflon on a compression fitting)
all my best,

You need to slide a piece of sheet metal behind your pipe prior to soldering. And if there is a little water in your pipe. Get a slice of bread, break in in small pieces and put it inside the pipe. push it in past were you are going to solder. And then quickly soldier the joint. The bread will keep the water away from your joint making it easier to solder. Bread dissolves once the water is turned back on. That is your tip of the day Gents. And or Ladies

Get a can of great stuff and spray a little behind the pipe. Enough that it expands out around the loose pipe. Or attach with brackets, wood and screws!

You could also buy this spray gel called Cold Coat it is a heat blocking spray gel by BernzOMatic. just cover the pipe and spray the gel and un cover and solder the pipe the wall won't even get hot. I found it at Orchard Supply Hardware.

after applying flux the solder applied on the free side will flow around to the back next to the wall all by itself.

You want to SOLDER a copper TUBE (SWEAT FITTING) close to concrete? Just solder it (clean, flux, heat, apply solder, wipe).
It's a concrete wall it's fireproof or just slip some sheet metal behind so no scorching.
