When should I schedule a pour in Key West?

Dry season Nov-May is prime pouring weather; Jun-Oct brings daily storms and high hurricane exposure - schedule early and keep curing cover ready.

Which Key West ZIP codes do you deliver to?

In Key West we map ZIP codes 33040, 33042, 33043, 33050 and 33051. Pricing is per ZIP — enter yours in the form and it's checked instantly.

When do I need 4000 over 3000 PSI?

Heavy vehicle traffic (RVs, trucks), structural footings per plan, or where your county/engineer specifies it. For a standard shed slab it's usually more than you need.

Is 4000 PSI required for a Florida driveway?

Not for a standard car driveway — 3000 PSI is fine there. Choose 4000 for RV, boat-trailer or truck parking, and wherever your county or engineer specifies it. It's also the default for footings and equipment pads.

Does higher strength mean the slab lasts longer?

4000 PSI resists cracking under heavy loads, but curing, drainage and proper control joints do more for longevity than strength alone. For most homes, matching the mix to the load beats simply going higher.
