Would I be able to use this to extend the width of my driveway about 2ish feet so there is more surface area to walk on? I wouldn't be parking on it.

A walkway can be placed beside your driveway using the WalkMaker concrete forms. Please see our project video at https://www.quikrete.com/athome/video-walkmaker.asp Please be certain to check with local building code officials to determine whether a building permit is required.
