Pipe Penetration - Repair Method 2

[ChalMel13]

Hi Everyone,

I need to repair some pipe penetration (fuel) on a concrete block wall. My understanding is that I need to leave some gap between the pipe and the wall to allow for the pipe movements. How can I patch around existing penetration in order to leave a gap around the pipe? Is there any specific method?

Cheers.

If you don't need to seal it just as two half shells of a bigger pipe.

If you need to seal there a lot of flexible pipe seals.

Thanks @LittleInch.

I need to seal the penetration as it is a bund. So, in terms of the actual repair should I:
[ul]
[li]use a bigger pipe around the current one[/li]
[li]then patch the blocks with grout and [/li]
[li]then seal any gap between the pipe and wall.[/li]
[/ul]

Is that what you mean?

Cheers

Loads of them available - see htis article

Really I would knock out the 4 blocks around the pipe, add two halves of a pipe one size bigger in plastic or steel and hold it in place with a ties and then build two bits of form work around these pipes and fill it with concrete.

Then you can seal the pipes using a proprietary seal system - many available, but not many are fire rated.

That wall is just a complete mess and nothing you do will make it better. IMHO.

Thank you both @robyengIT and @LittleInch for your response/advice.

Alternate 1: Reroute the piping over the Wall.

Alternate 2: Put a wall sleeve in the block wall, place concrete around the sleeve, then seal the sleeve and pipe with a link seal. The problem with this method is that the pipe length will change with temperature and the seal may not last.

Bimr's first solution is probably the best one.

What's in the tank? If the wall is for secondary containment, the contents will drive your sealer choice. Even though it's redoing work, up and over may be your best bet.
