Nice work chaps! What about if the wall is bowing/bulging above the floor joist level? This bowed brickwork is at waist height on the second floor of a victorian terraced house. It's definitely wall tie failure as all the neighbours have had the work done long ago. This one hasn't been touched and is now bulging. Obviously its due for remedial ties but I'm wondering if there's a way to pull the wall back to vertical again and get rid of the bulge, whilst the wall ties are being done? Hoping you can help a bit 🙏
Our repair doesn't pull the wall back in, it only stabilises it (prevents further movement). The issue with pulling it back is that you will inevitably introduce more cracking (imagine if you're trying to snap a flat piece of metal and you bend it back and forth until it breaks - it gets weaker with each movement). As you say, wall ties are probably your solution in your case 👍🏼. If the wall *has* to be back level then most often you are better off rebuilding that section of the wall, but it is quite an expensive and intrusive solution for something that is an aesthetic problem and not necessarily a structural one.
So the 2 bricks the bars run through are not going anywhere what about the rest of the wall.? How’s pinning 2 bricks back to joists going to prevent a whole wall bowing.🤷♂️
Hi thanks for the question! Bed joint shear strength is reliant on multiple factors including the coefficient of friction for the masonry, mortar strength and vertical compression. In almost all circumstances, this will exceed the load applied to Bow Flex. In comparison to traditional tie bars, each Bow Flex tie restrains a smaller proportion of the total lateral load over more positions, which increases the total surface area of the upper and lower bed joints loaded in shear, whilst reducing the span length of laterally loaded masonry.

Hi, it can vary dependent on the survey carried out. If you would like to contact us on 01672 812900 or sales@targetstructural.co.uk and we can assist you with any queries you have
Even if you fix the problem that causes the bowing wall (e.g. replacing failed wall ties, lowering the roof load etc), the wall won't just straighten itself, it'll remain bowed and inherently weaker than a straight wall. This solution allows the wall to remain stable while accounting for any additional loads.
@@targetstructural the wall is still bowed now. Surely any loads stressing the wall will now be sent elsewhere on the build. It will always find the weakest point.
Nice video Cliff. Love it 👍

What does a job like this cost? (just rough guide)

Can this be done to stone walls?
Yes! The procedure is almost identical.
seems like a band aid rather than a solution. shouldn't the actual problem be found and rectified?
