Still, I’d rather spend a bit more up front than deal with slab cracks down the line.

Couldn’t agree more—cutting corners early just means headaches later. I’ve seen folks skip geotextile to save a buck, only to end up chasing settlement issues. Your approach sounds solid, even if it’s a bit extra. Better safe than sorry.

Couldn’t agree more on not skimping, but sometimes folks go overboard with layers and end up spending way more than needed. I’ve seen people add two layers of geotextile when one would’ve been fine, or spec a vapor barrier that’s total overkill for a detached shed. It’s all about matching the solution to the soil and use case. Still, I’d rather see someone go a bit extra than cut corners and regret it later... just wish there was a middle ground that didn’t break the bank.

That’s really the heart of it. I’ve seen folks throw money at every “premium” layer, but unless you’re dealing with serious moisture issues or unstable ground, it can get wasteful fast. For most backyard sheds, a single quality geotextile and basic vapor barrier usually does the trick—no need to go full commercial spec. I always recommend a soil test before making decisions. It’s surprising how often people skip that step and just guess.

Couldn’t agree more about the soil test—it’s such a simple step, but it really does save headaches down the line. I’ve seen people over-engineer backyard slabs just because they assumed the worst. Sometimes less is more, especially if you know what you’re working with.

- Couldn’t agree more about not overdoing it.
- Soil test is step one, but I’d add: check drainage patterns too. Even a solid slab can shift if water’s pooling nearby.
- Seen folks pour 8” thick slabs for a garden shed—total overkill unless you’re parking a truck on it.
- Sometimes I’ll spec in a simple gravel base and 4” concrete, and it holds up just fine for years.
- Only caveat: if you’re in an area with clay or fill, don’t skip the compaction step... learned that the hard way once.
