Installing Basketball Hoop In Concrete3/25/2021
We use Hiltis, and Phillips on base plates for seismically designed pipe hangers and support.The post has a base plate welded to the bottom that is made to mount on four 58 threaded rods.
You are supposed to set the threaded rods into the cement slab when its poured, but I didnt do that. The concrete is an engineered slab with beams (trenches) and Im installing it over one of those beams. So, the concrete at that spot is 18 inches deep and 12 inches wide. As one option, I could get this type of anchor in the size needed for 58 and screw in some threaded rod. Im not sure if that would be strong enough as the plate will be suspended above the floor by an inch or so and there would be some lateral movement. Somewhere Ive seen some epoxy that was made for this purpose. You drill a hole, squeeze in some epoxy and insert your threaded rod. The post base plate requires 4ea 58 threaded rods set in a square shape 9 inches apart. ![]() Its designed to lower the height and dunk on, so its gotta support alot of weight. Still though, even with a basic setup youre looking at alot of weight up there waving around when a ball hits it. Be careful, you dont want that thing falling down on you after a layup conks off the rim. There is no metal base to install, just a template to bolt the allthread to when you sink it into the wet concrete. Turns out they relocate them quite often and use both Hilti anchors and Rocktite to reset allthread or bolts depending on the application. They did ask alot of questions about my cement slab to make sure it would support it and was thick enough for me to drill down deep enough to make it secure. Ive had a 300lb guy hang on it before I paid almost 2,000 for it (ouch).
