Injecting resin

mikeey84 · 15 Mar 2020

I've got a really deep (500mm) horizontal hole I'd like to fill with resin and a threaded rod.

Anybody any tips to get the resin as far back as possible so I don't get any voids?

Long reach nozzle?

My experience of anchor resins is that the nozzle is also the resin mixer so any additions to the nozzle would have to be done after the mixing process. This could be troublesome if the gear decides to go off quickly or if you need every drop of gear (waste in the long nozzle) or if you can't get the extender to attach properly.

I'm sure that if you squirt it in as far as possible that the rod will take a lot of the gear back with it and then you can add more as the rod is pushed back. Bit of a gamble though.

Yeah, there is not a lot of leeway with resin!

I've seen long nozzles, but they are still pretty short.

I thought of threading a nut/washer combo on the end to get as closer fit to the diameter of the hole as possible, so it pushes the resin back as it goes in.

May trial with something a bit more forgiving first like no more nails (I've got a couple to do)

Not all of it will need to be filled. Some resin pushed to the bottom, some down the thread, thread it in and then some resin around the top.

Otherwise the engineer would specify a much wider hole and a long tube injector, to fill it completely.

Push on a length of tube on the end of the mixing nozzle push in the hole and draw back as you squeeze in. Be prepared for the displacement of the same amount of resin down your wall and on the floor, but as has been said you don't need to go over the top with the resin but I always do.

My main tip would be to work fast with it, don't plan on on doing both at the same time with the same nozzle on your first attempt of working with this stuff. Get a spare nozzle for the second hole and concentrate on one at at time then what you have learned with the first you can take to the second.

I suppose the obvious question is why is the hole 500mm deep in the first place ,and does the threaded rod actually need to be embedded 500mm
