How to pave around plumbing waste?

[Mick_M]

Hi

After our reno, the new plumbing for our kitchen and bathroom has been left with a bit of stick-up for us to cut down, and they also left a couple of the bigger 100mm PVC domed covers (see photo). I also bought a couple of the smaller 100mm grated covers in case that’s a good option to finish these off.

This is around the back of our house. What’s going to be a simple  solution here, for something that looks decent, and doesn’t involve cutting more pavers? How are these domed covers, or the smaller covers, usually installed?

My plan right now is cut down the pipes so that the bottom of the domed ones fit flush with the top of the pavers, then use cream coloured general purpose mortar to fill in gaps between the pavers and the pipe. 

Any better options?

Hello @Mick_M 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your plumbing waste.

Your proposed plan of cutting down the pipes so that the bottom of the dome fits flush with the top of the pavers, then using cream coloured mortar to fill in gaps between the pavers and the pipe is a sound idea especially if you are not keen to cut pavers. Adding more pavers will require you to cut pavers which you are trying to avoid. I believe this would be the straightforward solution if you are after a simple tidy up.

Let me call on our experienced members @Dave-1, @Nailbag and @Noyade for their recommendations.

If you need further assistance, please let us know.

Hi @Mick_M 

I've not seen those raised dome grates before, and wonder what's the purpose of that design? Regardless I agree with your plan to use the traditional flat style. If you have a spare paver I would cut it to fit in the large space in photo one.

If this is the coloured mortar you were referring to then fill the gaps around the pipe, then it's not suitable. Its purpose is more for filling small gaps and cracks in masonry like brickwork and nothing deep and open like in your situation. It also has to be applied in a way that allows for its 10% (roughly) expansion. I would simply use standard uncoloured mortar. This one is pretty easy to use if you want a pre-mixed product.

Good Morning @Mick_M 

When my plumber installed my new sewage piping he left two of teh inspection pipes higher then the ground as the soil needed to settle after backfilling. He told me I could just cut off the top to lower the cap down (or I could let jim know and he would coem back and cut it) So I would go the route of cutting the height down so the domes will be flush.

Hi @Mick_M 

Anothe way of simplifying things is that you can get square grates which makes it so much easier to cut the pavers to go around the area (all straight cuts).

HI @Nailbag - yeah I don't know much about the dome grates - they're the ones the plumber left behind so I'd assumed they're fairly common for this kind of use? 

This was the mortar I was referring to - just a plain bag of general purpose cream coloured. Good to know about the pre-mix, that might come in handy for a few other jobs!!

Yes to that Mortar @Mick_M 👌
