How to fix anchors too loose in brick wall?

[CassM]

 

Hi, I tried to install a Daytek clothesline onto my brick wall using the Dynabolts suggested but even though I drilled 8mm holes for 8mm bolts the anchors are loose and are being pulled out by the weight of the clothesline. 

My brother in law suggested using Ankabolts and they do look easier but the 8mm ones are too wide to fit through the mounting brackets. 6mm ones fit but are obviously too narrow for the drilled holes. Is there something I can use to make the 6mm bolts fit in 8mm holes? 

Thanks for your help!

Welcome to the Bunnings Workshop community @CassM. It's terrific to have you join us, and many thanks for your question about installing a clothesline.

Are you able to remove the bracket and pull out the offending Dynabolt? If so, I'd recommend you then fill the hole to the brim with Ramset 300ml Chemset UltraFix Plus and re-insert the Dynabolt. Pop the bracket back on, but only finger-tighten the nut. Wait 45 minutes and then tighten a couple of revolutions of the nut, but do not tighten it fully. Wait another couple of hours and tighten the nut further. This allows the glue time to set whilst expanding the Dynabolt inside the wall. You'll effectively glue it into position. This is super-strong glue designed for this purpose.

This issue you are experiencing is due to these being hollow bricks. When the Dynabolt expands inside the wall, there is nothing to hold it in place. Typically, you might get lucky and hit solid material, but most of the time, at least one will fail as it expands into a void. This glueing method is likely the best option to try at the moment. If that doesn't work, let us know, and we'll move on to the next option, which will likely be moving the holes and using the Ankabolts in fresh material.

Please let me know if you have any questions.

Hi, sorry it took me so long to reply. It took me a while to find the time to get the products and then to attempt the fix. I managed to remove the bottom two Dynabolts ok but the top two of each bracket are stuck. What should I do if I cannot find a way to remove them? 

Thanks for your help

Hi @CassM,

While holding the outer sleeve with pliers, tap the bolt section into the wall. This pushes the bolt section further in and disengages the locking mechanism. If you are able to tap the bolt further in while holding the sleeve in position, that should allow you to remove the outer sleeve and bolt. Alternatively, you might have to look at cutting the bolts off and moving positions.

Hammer and pliers did the job! Thanks

Hi there Bunnings knowledgeable folk,

I have a related issue. 

again it’s a wall mounted hose reel. Holmanns brand from Bunnings. The wall is Hebel. The reel is mounted by large screws and wall plugs. They’ve pulled out twice. I’m thinking my best bet is this Chemset stuff. But can I use it with the large screws that come with the hose reel, or do I need to swap these out for something different? How do I screw the screws in so they are tight if I’m screwing in to a hardening gel?

thanks,

Andrew

Good Morning @ajperry 

Any chance of a couple of photos of the hose are thats being fixed? 

I was about to offer some advice and thought to have a quick squiz about the make up of a hebel wall. It makes me hesitate about offering advice on something I am unfamilure with.

So as a different option to hang the holmanns hose off the hebel wall. (will let @JacobZ or @EricL  answer that one) The option I am thinking is to install a 1.8m post  at least 600mm into the ground (with concrete) and bolt the holmanns hose to it. This way there is no strain on the wall, tho it wont look as streamlined. You will need to dig around 300mm off the wall as if you dig closer you will potentially hit the foundations of the house.
