Cracks in brickwork and gone through to breeze blocks

Hi lynne, A temporary aesthetic fix is to grind the mortar out and repoint, but this is very temporary and the issue will reoccur. The best fix for this is to take it down and start again unfortunately. Check the footings are deep and wide enough, and the mortar is the correct ratio of sand to mortar. To me it sounds like the footings have sunk, but it could be a multitude of other things. Ricky

Hi You can rebar it u basically grind out the mortar put rebar in it and resin it it then re point. Matt

Footings are failing, you'll have to dig down 1 metre deep beside footings and then in under original footings.no more than a metre wide section and underpin with a mass concrete pad . Once this done you can carry out brick work repair.

If the footing was an inadequate depth width then this could be the issue. Epoxy resin 3 pieces of glass approximately 1" by 4" at the top middle and bottom of crack. Also dig down on the outside of the footing untill you reach the bottom of concrete. If concrete is cracked if glass samples break within a short period of time then the rebar answer is your other option. Underpinning for a summer house seems a bit over the top.

The other answer was good but you can find out about the cracks in the brickwork by marking out the crack and fixing a piece of plastic across the crack and put a mark at this point then check the marks every two weeks to see if the crack is getting wider. As the other bricklayer said it could be down to the footings. Who done the footings etc. Did they go down deep enough (6ft) or wide enough (12 inches either side of the whole wall to stop it tilting. Are there any trees 🌲 near the construction as roots could be a problem. If the cracks stop after a certain time then you need a good builder who can supply and install re bow ties into the brickwork which are then fixed with a resin which will stop the brick work from getting any wider but you need an expert to do this kind of work. The last thing is you can do a pilot hole next to the building to see how deep the foundation are. If these are less then 4 ft minimum then you may need to start a again. Good luck.

Without seeing the work, It sounds like the foundations are not solid and the building is sinking.
