[Closed] Channelling into a concrete floor

Hora's got sledgehammer now.
Get him round to help.

9" grinder with diamond blade is minimum. Stihl saw water cooled is better (stops the dust) Dont forget to wrap copper in pvc tape or sleeve them with plastic ducts.

You want a chasing machine. Hire from the usual places. Make sure you get the dust extraction kit too.

There is a drill attachment for hammer drills that lets you chase out a groove I thought?

My Dad showed me this after letting me chase a couple of walls out for him one holidays from Uni. Thanks Dad.

Hora and WCA together? 😯

Why not put in some plastic ducting and then use plastic pipes (Hep2O or similar) for the heating that you can thread through after. I did that in a previous house with solid floors and it worked great. You can still use copper between the floor and your rads for an old fashioned look. Personally I wouldn't want to embed copper pipes in concrete - it's asking for trouble.

We are planning on putting ducting in so we can slide the plastic pipes inside. We just need to did the channel to sink the ducting into the floor.

Is that chasing machine basically just 2 disc cutters next to each other?

The little cutter we have has a diamond blade, it is just hitting all the stones all the time that is taking an age.

Just googled the story behind that picture Effinsafety. Blimey! I wouldn't be too happy if I'd bought a flat in one of those other blocks.

it's asking for trouble.

Its a WCA thread

I think you'll find it's trouble who is asking.

Will the chasing tool be any better than a disc cutter? It lookslike the same thing but with 2 discs

an electrician I spoke to said that any of the cheap ones tend to, as soon as there's any wear, end up with the disk pointing in slightly different directions.

I'd go with the 9inch diamond disk or even one of the the water cooled ones.

or just get some of that 'pipe duct that looks like skirting board' stuff and avoid curtting the floor.

I know! What a balls-up. A life lost as well. 🙁 At $2100 a square metre (so, roughly £70,000 for a tiny one bed flat by my shonky estimation, I imagine that might be quite expensive in China)), you'd perhaps at least want something that stayed upright.

And when you think this kind of corner-cutting and shonkiness is endemic in the Chinese construction industry... 😯

LISTEN TO THIS MAN FOR HE SPEAKETH SENSE.

Fascinated by the fallen flats - links?

Can't be too bad - didn't disintegrate when they fell. Need to shoot the guy who did the piling though 🙂

Here you go epicyclo:

Semtex?

No not sexual semtex (save that for mrs WCA as its precious and runs out in your 50's)

I want to set the central heating pipes into the floor

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

Avoid burying pipes unless thare is [u]absolutely[/u] no alternative!

When they burst (and they will), it's a nightmare! Your building insurance won't cover you for the damage caused investigating where the leak is coming from (don't ask my why). So you will be tearing up flooring and will have to pay out of your own pocket to replace it, desite paying for buildings insurance.

Aside from this, channeling out a slab could be very expensive and if you use an angle grinder, you'll cloud the whole house with dust.

Do you self a massive favour, find alternative runs to going through concret floors.

Spongebob - We are putting ducting into the floor so the pipes can be added/removed/replaced without disturbing the floor. The house is an empty shell at the moment so the dust isn't an issue.

another alternative could be create the channel then lay a clipped-together boxsystem in there with a 'lid' ontop for access if that makes sense? I imagine they use these in offices etc.

hora - similar to what we are planning but being able to slide pipes in and out means we don't need to lift the carpets or laminates to fix stuff

concrete corrodes copper incase you were thinking of bedding them in.

Yes. And also what rightplacerighttime said about the cost of wear on the disks when you are hiring - it's horrendous.

leffeboy -

Note: Hire rate includes diamond wear.

2 minute job...

Please don't recommend something like that to WCA. 🙁

T'is done. Borrowed a mates big disc cutter. It sh1ts on little stones.

Bit dusty mind.

Back to the wood chip removal at the weekend I guess

Good man.

I'll come and help if you want. Not a problem at all. Just let me know.
