Asphalt softens and ruts when St. George hits 105°F — and that happens for months at a time. Concrete doesn't. It stays rigid, holds its surface, and gives you a clean, durable result that lasts decades without annual resealing. For concrete driveways in St. George, the desert climate actually works in concrete's favor.
A well-built driveway starts with proper base prep — compacted gravel subbase, correct slope for drainage, rebar or wire mesh reinforcement, and a desert-appropriate mix. Cut corners on any of those steps and you'll be replacing it inside 10 years. Do it right and you're looking at 40+ years with minimal upkeep.
