The math

QUIKRETE's data sheet for Concrete Mix No. 1101 gives the yields: an 80-lb bag makes approximately 0.60 cubic feet, a 60-lb bag 0.45, a 50-lb bag 0.375, a 40-lb bag 0.30. The volume of a round hole is pi times the radius squared times the depth, all in feet.

Why the manuals ask for more than the math

Every maker's count runs 20-40% above the geometric volume, and for good reasons. The hole is never a perfect cylinder: a post-hole digger flares it and an auger wanders, and every inch of extra diameter is about 12% more volume at 16 inches. The manuals want a form for the top 4 inches (the Silverback manual specifies 20 inches across at the form), which adds volume. Some mix stays in the wheelbarrow and on the shovel. And a footing that comes up two bags short at the end of the pour is a footing with a cold joint at the top, exactly where the anchor plate sits. Buy the manual's count plus one, and take the unopened bags back.

Buying and mixing it

Eleven 80-lb bags is 880 lb, which is a pallet-cart load at the store and a truck bed, not a sedan. Goalrilla's guide asks for mix meeting ASTM C387 (QUIKRETE Concrete Mix does, per its data sheet), mixed at 6 pints (2.8 L) of water per 80-lb bag to start and up to 9; the Silverback manual says to follow the bag. A wheelbarrow and a hoe mix a bag at a time; a rented drum mixer does three. Both manuals pour to about 18 inches below court level, set the rebar, then finish the pour, push in the anchor and level it. Do not pour below 40°F without hot water and a curing blanket (Goalrilla), protect from freezing for 48 hours (QUIKRETE), and give it the full 72 hours before the pole goes on. How to install an in-ground hoop has the day-by-day.

How we picked

What earns a pick on this page

Every pick here is built from figures you can check for yourself: the maker's published backboard, pole, overhang and adjustment specs; the hole size, bag count and cure time printed in its install manual; the warranty term in the maker's own wording, exclusions included, with the date we read it; and the failure patterns owners report (base cracking, backboard fogging, two-piece pole lean), which shape the “skip this if” line. Every figure links to where it came from.

Those figures go through one fixed rubric, so an 8.1 here means the same thing as an 8.1 anywhere else on the site and the top pick is the one that earns it for the driveway it is named for. Commissions never set a score or decide a pick. The rubrics and their weights are published.

Questions

Frequently asked

How many bags of concrete for a Goalrilla?

Eleven 80-lb bags per Goalrilla's current installation guide, with 12-13 recommended as a buffer, for a 16-inch by 48-inch hole. The older B1002 anchor manual says nine.

How many bags of concrete for a Silverback or Goaliath?

Nine 80-lb bags per the Silverback SB60 manual, for a 16-inch by 36-inch hole with a 20-inch form at the top, plus four rebar. The Goaliath Ignite and Prodigy use the same 7-inch anchor.

How many bags of concrete for a Lifetime basketball hoop?

Lifetime's guide gives weights: 420-640 lb for in-ground systems (about 5-8 80-lb bags) and 1,040-1,680 lb for bolt-down systems (13-21 bags). Check the manual for your model.

What kind of concrete for a basketball hoop?

Standard bagged concrete mix (Goalrilla asks for ASTM C387; Pro Dunk asks for 3,000 psi or better; QUIKRETE Concrete Mix No. 1101 is 4,000 psi at 28 days). Not mortar, not sand mix. Fast-setting mix is not required by the manuals we read; the 72-hour cure applies either way.

How long does concrete need to cure before mounting a basketball hoop?

A minimum of 72 hours per the Goalrilla and Silverback manuals and Lifetime's guide; Goalrilla recommends mounting on day 5.
