this is what we use at minute mate but this a old building on a main road, but the timber is rotten in a lot of places and it has got to go 6 lifts, there is no brickwork it is straw and render someone lives there and it is right in a windy area any time of year so need to tie in as much as possable.
Cant you tie a rope around the chimney stack ? always works for us
Tie front to back through building with tube!!
When repairs have been made to structure then change to Apollo ties.
