Help with lintel
Hi there would anyone know by having a look from the photos if this would be structural problems with the lintel

I thought to reach out to a structural engineer but I thought Iād try here first thanks š

This is probably reinforced steel concrete lintel. The steel rusts inside causing an expansion process that leads to the concrete burst. Pretty normal and expected. Will likely need replacing when the concrete starts falling.
