Always add 5–10% to account for spillage, uneven subgrade, and rounding. It's easier to have a little extra than to run short mid-pour.

Ordering Concrete the Right Way

Always Order a Little Extra

Add at least 5–10% to your calculated volume. Subgrades are rarely perfectly level, forms aren't always exact, and running short mid-pour is a real problem.

Have Your Dimensions Ready

When you call to order, have your length, width, and thickness written down. It makes the process faster and ensures you get the right amount delivered.

Consider the Weather

Extreme heat speeds up curing and can cause cracking. Freezing temps can ruin a fresh pour. Plan your pour for mild conditions and have protection ready if needed.
