Does anyone know the best way to make this ramp nonslip? We get a fair amount of ice and snow and there are a couple elderly folks using the ramp.
We tried a basic nonslip rubber mat, but the grooves just hold ice and snow so don't really help.
Our current ideas are maybe adding rubber stair treads every board or two, or maybe tacking little strips of wood to every board.
If slipping is a concern, you should also put up a better railing.
The building codes in most places would require balusters or otherwise closed in sides on a ramp like this. If someone does slip, they can go under the rail and off of the porch/ramp.
Also, the vertical supports for the hand railing seem insufficient. Supports for railing are generally 4x4, connected with bolts, and there would be a couple of more of them on the long run. A 200lb+ person falling has more than enough force to snap some screws through a 2x4.
