Sealing a concrete panel

[tomg]

We've got a concrete panel which is sat on top of a concrete floor as a pen division. Problem is that effluent is running underneath and making a mess.
What's the best way to seal underneath it? Thinking of lifting it and setting it back down on a bed of mortar.
Any better suggestions

Cheers Tom

We've got a muck store which is sealed; we used the stuff provided by the panel suppliers and generally it's pretty good. Panels are placed straight on to a flat slab and then sealed in to the grove between the two. It's hellish sticky though; sticks to absolutely everything. We've found that the panels do tend to move a little even when they're not loaded so I'm guessing a mortar joint would crack over time.

Edit: There's a similar thread here with some suggestions

If you are able to lift the panel buy a roll of Tok Strip - it is the bitumen strip used to make the joints between manhole rings waterproof. Simply roll it out and set the panel on top of it. Any merchant selling manhole rings will have a version.

We use a product like this for sealing panels when installing them.

I just mixed some strong darbo and troweled it along the bottom....works a treat
