So, you're dreaming of a new concrete patio, huh? Maybe a nice spot for the grill, some outdoor furniture, a place to kick back after a long week. That's a great idea, actually. A well-built patio really adds to a home's value and your enjoyment, no doubt about it. But I've seen a lot of folks around Spokane make some pretty common blunders when they're planning or hiring for these projects. Let's talk about what to watch out for so you don't end up with regrets.
Mistake #1: Skipping the Site Prep (Or Letting Your Contractor Skip It)
This is probably the biggest one, and it's where a lot of problems start. A concrete patio isn't just poured on top of whatever's there. It needs a solid, stable base. Around here in Spokane, especially in areas with a lot of clay or where new developments are on disturbed soil, you just can't assume the ground is ready. If a contractor just digs out a few inches and pours, you're asking for trouble.
- Not compacting the subgrade: The soil underneath needs to be properly compacted. If it settles unevenly after the concrete is poured, your patio will crack and sink. We're talking about heavy equipment here, not just a guy stomping around.
- Ignoring drainage: Water is concrete's enemy. If your patio doesn't slope correctly away from your house, or if water pools underneath it, you're going to have issues. Think about how water flows in your yard, especially during our spring rains or when the snow melts. A good contractor will plan for this, believe me.
- No proper base material: You need a layer of crushed rock (like 4-6 inches of compacted gravel) underneath the concrete. It's crucial. This provides a stable, drainable layer that helps prevent frost heave and settlement.
Mistake #2: Going Cheap on the Concrete Mix
I get it, everyone wants to save a buck. But concrete isn't all created equal. There are different strengths and types of mixes, and using the wrong one for a patio is a false economy. You want a durable mix that can stand up to our Spokane winters – those freeze-thaw cycles can be brutal on weak concrete.
Ask your contractor what strength concrete they're using. For a patio, you generally want at least 3500 PSI (pounds per square inch). Anything less, and you're risking premature spalling, cracking, and a shorter lifespan for your patio. Don't be afraid to ask for specifics. If they can't tell you, or they just say
