methods to keep rock from falling

[miatawnt2b]

I am interested to hear different approaches for keeping rockscapes stable. I am kind of against using epoxy to glue all the rock together since I do like to take things apart and re-scape occasionaly.

Let's hear your ideas.

I just stack mine. I've never had a problem. Some people use zip ties or drill holes in the rock and build a pvc structure. Never had an avalanche yet. Fingers crossed...

I debated using epoxy as well but did not for rthe same reason. i like to move stuff around at times. I just tried to fit the rocks in place as best I could. Tried to lock some in place like leggos. I have one or two kinda shaky spots but for the most part it has held up fine.

Carbide drill bits, zip ties and fiberglass pins (like those used in Keystone retaining walls)

I've used epoxy applied between rocks at strategic points as a stabilization aid. A small amount just around contact points is enough to add alot of stability. There is never any problem getting them back apart. The epoxy bond just isn't that strong. It works well for stabilization despite being relatively weak since it doesn't need much strength for that purpose- mostly it just needs to be incompressable. I don't put it everywhere, just in areas that have a slight tendancy to wobble or move easily.

I just threaded all mine onto 3/8" acrylic rods. They will never fall over. A must, IMO, for tanks like mine (30" tall but only 18" front to back - impossible to balance).

I used acrylic rods as well. Only on the pieces I didn't think I would end up moving. But I didn't epoxy them so if I end up rearranging, the rocks can still be taken apart.
