Limited use concrete anchors - moisture

[mhulbrock]

I have a tubing bender that I just installed into my slab. Drilled and set 1/2 anchors in the floor. Most of the time the bender is not setup and there is a vehicle parked in that location. The anchors remain, but water can go into these holes now.
Is this an area of concern? Should I fill the holes with something with the anchors in place?

thanks

How about rubber or plastic plugs?

Just screw some short bolts back into the anchors. You could put gaskets on them to provide a tight seal. Find something in the plumbing section or you could use drain plug gaskets depending on the size of the bolts

Set Stainless anchors and plug / abandon the standard steel ones. Regular steel ones will rust up after a while when water and winter melt gets in them bolt or not. Hilti sells stainless drop-ins.

Mine are stainless. I feel even with the bolts fully threaded, water can seep around the anchor. Does it even matter?

No it doesn't matter. Installing a bolt will keep the hole clean but you could always just blow any dirt out with compressed air when you need to reinstall the bender. I wouldn't worry about water.

Personally, I'd put in a short bolt that has been coated with used motor oil every time I move the bender. Overkill I'm sure, but quick and cheap insurance.

I have some anchors embedded in concrete. I plug them with a short piece of all-thread or cut off bolt with a saw kerf cut in it for removal. The saw kerf allows removal without a bolt head extending above the floor. The plug is liberally covered with anti-seize. Before you use grease or anything caulk around the hole to seal it.

Filling the bolt holes will do little good because concrete is not waterproof.

If you are concerned about anchor failure due to corrosion, you need something rated better like stainless steel.

Installing an oil coated bolt will preserve the existing threads in your anchor.

Rinsing the area with clear water after winter to help remove/dilute the salt would be good.
