Manhole Benching by David Macefield

[@drainfast-uk]

Very satifying to see a manhole and drainage system to look this spotless. Great work!

[@EppingForest304]

Lovely work… great ground worker skills 👍

Beautiful work. Underground is no joke. From another underground worker.

[@Starbuckin]

Yes it is beautiful! I've wondered what this kind of work was called since I was a kid and popping the lids and taking a peek, now I know!

I need to dig a trench down to my sewer at 3.22m so Water corp can put on a T junction. The plumber then needs to extend pipe perpendicular into my property. I have manholes with ladders like in this video, I was thinking I could use them to avoid the high cost of trench boxes. But after digging down ti the sewer and putting manholes in, What would be the best way to get the pipe that Tees off into my property past or through the manhole? Concrete saw maybe? Hoping you can feed me an idea or two. Thanks 🙏

Hi, if I'm applying grano over some existing concrete which I put in a few days ago, is it necessary to use any kind of bonding agent or slurry? I'm going to mix SBR in with the grano. Thanks, great skilled workmanship btw, don't see too much of that nowadays.

[@m200cey]

Hi mate, I wet the concrete and ring or raisers, just water, so Grano don't crack

[@deemdoubleu]

@@m200cey Thanks a lot, that's good to know

[@Ripper36068]

I use a cement/SBR mix (after cleaning any and loose material from the drain) as a bonding agent then go over it with a sharp sand cement mortar again with some SBR in too!

Amazing work

[@rochie3rd]

omg are u on drugs

[@DH-ce8iv]

Do you have to pour a concrete base first before the benching?

[@m200cey]

Yes, stiff strong mix c4, form shape and level top to sit one concrete ring on..

[@jameshughes8309]

@ 1 min 22 if that's the rough form in conc ready for the grano finish to go on next, iv'e got a lot of time for that plenty of texture for the layer to key into nice work

[@m200cey]

1.22 that's Grano been shovelled down, only 1 meter ring so reach with shovel.

[@davidpatrick3533]

Nice work! What concrete mix do you use?

[@m200cey]

Been a long time ago, 4 x Grano 2x cement 1x sharp sand, 1-3 inches thick benching over concrete, if dry wet it first or my crack.

[@ferenctoth9237]

@@m200cey I think that's too much grano. I always been told you only need a bit of grano just to hold the mix together

[@joerush2212]

You don’t need sharp sand if your adding grano to a mix use building sand for a better Finnish. And plus there’s more lines in that benching than on pablo Escobars kitchen table rrrrroug

[@m200cey]

Lol, just had a line you self haven't you mate... Not skimming bedroom ceiling, will never be seen again.. But yeah some building sand is OK..

Hii sr what does benching means?

[@mosher2791]

Wow give me some tips I bloody hate benching

[@m200cey]

Hi Mate, take your time and try to enjoy it.. make the shape with your hands first, use a long plastering trowel for straight edge each side of channel and round the outside ring, small trowel finger pointer over sofits of in and out pipes..
