Anchor for basketball rim to concrete wall.

I'm in a little spot of trouble here...

I am installing a basketball rim onto my block concrete wall. The red head concrete sleeve anchors will not grip and just spin loosely.

I pre-drilled 3/8 holes and cleaned and vaccuumed the holes. But I think I messed up and made the holes too big or got them "wallowed" whatever that means...

So, I am now stuck with 3/8 holes and am wondering if anyone has recommendations. Should I use some sort of concrete epoxy to fasten the bolts into the wall. Something like InstantBond...

Any help will be greatly appreciated! I have to use the existing holes they are the only place I can mount the rim...

IMO you would probably be better off if you would forget your idea and instead, bolt the hoop to a large piece of 3/4" plywood (backboard) first... and then use smaller tapcon screws to fasten the perimeter of the backboard to the block.

You need to use a self expanding system that will wedge itself in place as tightened. I use the following type. They work even if the hole is slightly oversized.

In your application I would go with the sleeve anchors and I think I'd upsize to 1/2" bolt size.

Assuming the voids in the concrete block weren't filled in you can also use toggle bolts. (Not sure what "block concrete" is but guessing it was a typo for concrete block.)

Xsleeper thanks, using a backboard is an option I am trying to avoid. But it is my last resort.

PJMax, yes, thanks. I am using sleeve anchors that look almost exactly like that... these onesName:  541545c0-650d-4e03-bd2b-2fa55fea22ef_1000.jpg

Size:  26.6 KB I read elsewhere that people have trouble with these slipping... hence the epoxy solution that I was hoping would work.

ray2047, thanks yes, I mean concrete block. I will look into Toggle bolts. My google fu seemed to indicate that epoxy was the best way forward but it seems like that is not a common solution. It sure would be the easiest.

The problem with the ones you choose is that they don't work if the block is hollow as only the end expands and if it's in the hollow..... game over. You need a full expansion anchor.

Toggle bolts require a large hole to get the expanding wing in.

A toggle bolt with a pivoted bar rather then wings uses a smaller hole.

Ahhh! thanks PJMax, I realize where I went wrong. I do have hollow blocks and I see now that I have the wrong type of sleeves. Off to the hardware store!

Bolts

If you have access to the back side of the wall, I would suggest 3/8 in. through bolts.

I'll have to agree with Ken. Carriage bolts would be the only way I would mount a basketball goal to concrete, whether it is block or a monolith.

Unfortunately, I do not have access to the back. Do you think that the sleeve anchors wont take the sudden stresses from the ball hitting the rim? No one here is going to be hanging on the rim!

I don't understand the reluctance to install a plywood backboard. The block will alter how the ball deflects.

Just to round this off. Its up there now with lag sleeves and screws. Feels firm. We shall see. Thanks all for your time.

Marksr, thats a good point, I did not think of... the fact that the ball will bounce differently off concrete. The reluctance is the added cost, effort and the fact that in the South West sun, I dont think the plywood will last well or long

Hope it works for ya. My feeling is that the blocks are too soft for that type of anchor and that over time, those holes will become loose. Hope I'm wrong.

Just round this out for anyone happening upon this thread. Turns out XSleeper was right. It could also be that I did a poor job of installing it. But either way the darn thing has worked itself loose.

For now, I am just going to put a thin bar across it to fix it down and screw that in with tapcon.

So you don't think carriage bolts through the entire wall backed up with wood would be more secure?

Installing a rim directly to a concrete wall is a very poor idea. But after a few trips to the emergency room, slamming one's body into hard concrete following a layup, perhaps you'll agree.

However you attach it, you might want to get it right. Basketball rim kills kid.

Late to the thread, but IMO the rim should be mounted to stand off the wall otherwise, as Bridgeman posted there will be painful collisions with the concrete.
