Could anyone point me in the right direction with regard to wall tie selection and fitting please?
I am cutting out a wall below a window to fit a sliding door and as part of the building standards process I have been asked to include a check on the drawings that wall ties are present within 225mm of the opening - the wall was built around 1990 so I am going to presume that they are not present or may be in poor condition. I want to be sure that I choose the right product and fit them correctly as I am aware there are different types. Most of the info I can find online on retrofitting ties presumes that the wall is closed and the ties need to be added through a bore hole. As the wall is rendered I'd rather not do this and add them via the opening if possible.
It is a cavity wall, brick on both leaf's, I believe it to be around 100mm cavity, filled with EPS blown in insulation. My thinking was that rather than pull out all of the insulation, that I would just fit new wall ties near the edge of the opening at 300mm spacing.
I am presuming that all I need to do is grind out the mortar at the joints, fit the ties and fresh mortar pressed into to hold them in position.
If I have anything wrong in the above I would appreciate being set right!
Also, if anyone was able to point me towards a suitable product, or somewhere I could get advice on the right type of tie for this application, that would be greatly appreciated.
