Removing concrete path up against external render/plasterwork

paddy147

Whats the best way to remove a 5 inch thick concrete path and not break off the external render at the bottom of a wall??


Thanks.:)

Cut the concrete path with a consaw/angle grinder tight to the bottom of the wall where the render meets it - you may need to do it at an angle.

Im looking to get that concrete strip removed and continue the block paving from the driveway up the rest of the side.

The last thing I need or want is the plaster/render being knocked off at the bottom though.

Hi Paddy
there will be little bonding between the slab and the wall....so I would'nt be sawing up against the wall. Saw a line, say, a foot out from the wall down each side- smash up [with sledgehammer] and remove the middle section,knowing that any vibation wont travel as far as far as the wall.Now you are free to lever and pull the remaining strip[bit at a time] away from the wall render without damaging it.

Just had the same problem.

Con saw at an angle. Not too close. It kicks.

The con saw may not go right through in which case just be a little carefully as youget close to the cut with the ground breaker.

Was the wall plastered before the path went in?

Should have been, but .... ya never know.

The wall was plastered and then the concrete path put in.
But the wall was then replastered after the plaster cracked.

I had the plasterer back and he cut a strip out (where the crack developed)and I also had a structural engineer on hand to see if it was a foundation problem.

Thankfully,it was just the render that had cracked and the wall was replastered with a plastic expansion strip added too.:)
