Many very old houses built over 100 years ago have extremely narrow, small stair landings at the top or bottom of staircases that are dangerous for residents to use, especially when carrying large items up and down the stairs. Widening this small stair landing by 300 to 400 millimeters using traditional masonry construction would require building an entire new foundation, which is extremely expensive and disruptive. But using lightweight EPS Cement Sandwich Panel, you can build a new extended low wall that defines the new wider stair landing, without adding enough weight to require any new foundation work. The panel is rigid and strong enough to act as a stable low wall, and you can top it with a simple wooden handrail to complete the new safer stair landing design. This simple renovation makes your old house staircase far safer for all residents, eliminating a major common home accident hazard that plagues many older vintage homes. The whole project can be completed in just a couple of days, for a tiny fraction of the cost of a traditional structural stair landing extension.
