Removing 1 row of concrete block
 

Hi,
I'm building a courtyard wall using mortared concrete block (8x8x16).
According to my wife, I've built it one row too high. Is there an easy
way to remove the top row without destroying the row underneath? I
used type S mortar, which I assume is a lot stronger than the block
itself. Thanks.

A two pound hammer, but only hit the top blocks and not the course of
block below. This will work; unless you have steel our poured the top
blocks.

Safest way would be to cut through the mortar joint with a diamond saw
from both sides of the wall. If you can only get to one side, you can
rent a saw big enough to saw all the way through. It's a messy, dusty
job, (unless you rent a wet saw, in which case it's only messy.) But
it will leave a nice clean edge that won't require much clean up.

If you just built the wall, the mortar may not be full strength, and a
well placed whack with a small sledge may do the trick. Of course you
run the risk of damaging one or more blocks in the lower row, which
would then have to be sawn out and replaced...

Third option, get a less fussy wife :-)

HTH,

Thanks Guys! So what is the cure time of mortar? I put the last course
on 2-3 days ago..
I think I'll go out tonight with my hand sledge hammer and see what I
can do. I do have
easy access to both sides, so a rented wet saw is option #2. My
neighbors would kill me
if I used a dry saw; I have about 38ft linear feet of wall. Regarding
a less fussy wife, that
was option #1 for a good while :)

Not familiar with type S. I suspect that as long as you don't have
anything on top of the wall, the first layer will come right off.
Give the end block a couple raps with the end of the handle as your
first try. I have removed block from teh middle of a wall (plumbing
access and install a new door) that was laid back in the 40s with no
problem. The mortar is more a leveler than a glue.

Grab and/or pull a block loose. Work from there across the top course
to remove.

Trust me the mortar in a few days is not set.

The block mortar is not the strong point; nor, will it be.

Pull the first / top course off by hand....

Wow! Your wife wasn't supervising while you built the wall? Ask her
if she'll marry me.

She was supervising of course. After I put on the last row she change
her mind. I explained to her this isn't like moving furniture around.
At the end of the day we compromised like married couples do: the wall
will be the height she wants and I'll do the work....:-)

Ah the great compromise and rule #1. If she ain't happy, you ain't
happy. One must learn that the pants is the boss and what he decides
is what happens. Of course he must be sure that what he decides is
what she wants.

just in case, find out the permit office specifications on height
width depth and foundation footers for support of the wall, and zoning
requirements for setbacks from the property line. you may be taking
down more than even your wife planned.

Yeh, I had a nice little chat with the city's head building inspector
*before* I started the project to make sure I met all setback and
height requirements. I don't know if other towns are like mine, but my
town has the inspector's do 'desk duty' for certain hours in the day
so any dummy like me can go in and just discuss a project to insure
all permitting/zoning codes are met. I think the theory is that this
cuts down on unpermitted work. Anyway, I find it to be a helpful
service
