To be completely honest with you, picking out pretty stone colors is the easy part, but ensuring the ground underneath doesn't turn into a wavy mess after one winter is where most people get burned. I spent weeks reading through local forums trying to figure out how to stop pavers from shifting when heavy trucks park on them. I stumbled across some incredibly solid structural advice on https://oakshs.ca/ajax-interlocking-services/ that breaks down the exact mechanics of deep soil excavation and geotextile stabilization layers. If your installer isn't digging past the soft topsoil and packing down a massive gravel foundation layer by layer, your brand-new driveway is going to buckle as soon as the first big freeze-thaw cycle hits.
