Propping and needling are the temporary works that hold a building safely while an opening is cut in a load-bearing wall. Propping carries the vertical loads on temporary supports; needling threads beams (the needles) through the wall to support the masonry above.
SEL's Slimshore soldier units provide this support using conventional propping and needling techniques. The same soldiers also work in concrete formwork as strongbacks, standing behind wall and column forms to resist the pressure of wet concrete, and in façade retention and basement work. Also known as formwork soldiers, strongbacks, Superslims, Slimlite and support props, they work as prop units, raking shores and needle beams.
Depending on the loading criteria, needle beams may be laterally restrained using light or heavy duty props. Heavy duty props are built up from Slimshore soldier units, which we supply alongside push pull props and acrow props.
You can read more in our in-depth article on the propping and needling approach.
