Like a front door, a home’s front walk is a welcoming feature. So if your walk is settling or crumbling, you should consider replacing it. True, it’s tough work, but it can be accomplished in five distinct steps: demolition, grading, forming, placing, and finishing. But one word of advice before you start: Order the right concrete. For walks, this means an exterior-grade 2500- or 3000-psi mix with air-entraining agents added. These agents form microscopic air pockets in the concrete as it cures, and this allows ice crystals to develop in cold weather without damaging the concrete’s surface.
