Cavity wall in shed problem,

Tawny Owl · 25-05-2013 05:45PM #1

I got a shed built last year but have noticed today a crack about 4 feet long in the mortar section I can see day light coming through, can I chip away the old mortar and mix up a cement and sand mix and push it into the crack and will it be ok, the crack is very small but worried.:eek:

Is the crack horizontal or vertical? Middle or end of wall? Running away from a window/door? If it's horizontal, how high off the foundation?

Hi horizontal about 4 feet high from the floor what do you think?

Sounds like a foundation problem..or could be the block work is not properly tied in ?. Might be worth getting a Brickie to look at it.

looks like the foundation is ok, would it be the way the mix was done , and can I sort it out sorry about all the questions also as I said can I do a little sand and cement mix and add it to the wall.:eek:

I've seen similar repairs done by raking out the old mortar/sand and the new mix put back in the joints using a type of Icing bag. Sounds weird but it actually works better than a pointing trowel. It's gotta be a pretty wet mix but the "icing bag" covers every gap until it squeezes out the other side.
