Thread: Howto:- Repair hole in stormwater pipe

I've repaired something similar to this by placing something over the hole then putting rapid set concrete over it to seal the whole pipe! Worked Great!

yep.

Stick a bit of crushed up newspaper in the hole for formwork, and just whack some concrete round it.

Ok "Round It" and "Seal the whole pipe" have got me worried. Do I need to fully enclose the pipe in the concrete or is it enough just to cover the top section?

And thanks for the replies folks

If you've popped a hole through it, there's a good chance there are other cracks, I'd expose the top half, and just get enough concrete round it to satisfy yourself it isn't going to move when you cover it all up again.

It's not critical, all you are doing is preventing dirt washing into the hole in the future. If the pipe is going to take a load of some sort, for instance if you are going to drive over the ground above it in future, err on the side of caution, and stick a bit more concrete over it.

My worry is the ROOTS you get.

Tree roots do a lot of damage.
Me?
I'd concrete a band around the Pipe a foot or so either side of the Hole.

I would a bonding agent like Bondcrete or use one of the many epoxy products that are available. If the pipe is the type with the glazed finish I would lean towards the epoxy type. Link below may help.

Use "quicks", these are the rubber sleaves that you fix to a pipe with a s/s hose clamp. I have used them to fix a section in a sewerage pipe, no problems. So stormwater should be no problem.

Just dig up enough pipe to cut out the damaged section cut a new section of pipe a bit smaller than the section to be replaced. Slip the sleaves onto the new section and lower into hole to line up with ole pipe. Slip the rubber sleaves over the old pipe end and fasten.

Hole fixed and water proff so will not encourage root growth.

ps have also used this method to insert a new link in an existing system.

I would clean up the area, put a bit of newspaper form as stated above put about 1/4 of a tube of roof and gutter silcion over the general area and then pour concrete over the whole lot to give it strenght for loads being place on top of it in the future

My father once did something similar to a sewer pipe. We wrapped the pipe with roofing felt (Tar paper or roofing underlayment or the black stuff on the roof under the shingles or the black stuff behind the stucco) about 50mm past either side of the hole. Then we put concrete around the wrapped pipe extending about 150mm beyond the roofing felt. Because it was a 'black water' pipe we felt that fully encasing the pipe was necessary. He lived in that house for about 10 years after the repair. Never noted a problem.
