It is one of those hollow cement/crushed stone stairs outdoors. The top step has a crack and small hole. ( Because of such changes in warm to cold weather this must have happened) There must be a fairly easy , non-expensive way to try and repair this step before it caves in
I use 3 parts of Portland cement to 2 parts of sand for such a repair. First take and clean out the area of all loose materials and then coat it with a coat of Latex paint. Then mix the Portland and sand dry, then add to about a gallon of the mixture a 1/4 cut of that latex paint, add water to suit giving a consistency of tooth paste. Fill the hole, let it sit for at least 2 hours, then scrape it neatly with a trowel, leveling it. This bond with the latex is about the best around, better that any sort of stuff sold at Lowes or Home Depot. Our local hardware store has Portland cement in 10# bags so you dont have to go out and get a 100# bag. Buy your bagged sand right there too. DO NOT use the premix stuff ( sand and cement) in a bag, simply not enough Portland in that stuff and a sure way to have a failure of this patch.
