Thanks for the input👍

2 storey need reinforcements bars at foundation, ground beams and column stumps

@@entername_ approximate 225mm or 9 inches. We followed the existing house foundations depth! Hope this helps

You can make it any thickness you want based on what your doing

Absolutely NOT.

You could yes. But it isnt absolutely a MUST. Therefore by not doing it you save £££

If absolutely not what many countries it is a must? Because UK have it's own way and cracks later.

@@endicous Utter Shite

It certainly was, the 600mm concrete was a strong mix. Its was a dark grey/blue colour and was tough stuff.

Yes I know, we generally get them cut down as the last thing I want is to do pile foundations lol. There are always checks before we start as that saves loads of trouble as you said.👍

@@foundationgood123 your solution of cutting them down is good but be aware that this could back fire. Always advise building control of when you cut the tree down, what type of tree and how far away it was. Soils, especially clay shrink and contract with moisture content which can lead to structural damage if not accounted for. If you don’t make building control aware then you could be liable for any repairs. Often a structural engineer can design a solution that doesn’t need piles.

@@BerkleyBuilds Yeh mate, I always work with Building Control its a wise move

Boxing Fisherman it depends on the ground, did you see how hard the ground was to dig! A meter depth is the norm however if the ground is poor the depth will have to go deeper until the ground is firm. A meter depth is below the frost line and the drought line!

@@foundationgood123 ... After watching i did notice the extra hard digging below grade. Your area must allow variations in the footers depending on soil or bedrock. I wondered about the design w/o rebar too.

@@pensive69 were we are is min metre deep and if you don’t hit chalked deeper

70 slump with a little water ;)

شكرا لك يا صديق -:)

Stinky Pete hi, thanks for the input. To answer your question we did not need to go any deeper with the concrete as we followed Greggs this team foundation to the house. The ground was very far I was on the video sure are you breaker To break up the hard ground. The local authorities were happy with that and gave us the go ahead to pour the concrete. Hope that helps!

Thank you so much!!

yes

How deep is the concrete for foundation

You boys not heard of blazer level.

Yes, I have two videos showing how to do that, you will need to ruse a kem resin to fix the-bars into the foundation, you can get this from any builders merchants or DIYstores!

Not on spec

@@DaysOfDarknessUK Thanks very much for the reply, was trying to work out if there was minimum a depth of concrete. eg trench 1 metre deep, concrete footing "so" deep and blockwork "so" deep. Hence knowing the distance between the DPC and the top of the footings would tell me what depth of concrete should be used. Thanks for the input though.

Dave Comber Not on this job, I’ve used a pump on my other video where it was awkward to get to and was trench filled (had critics saying about pumps and trench fill LOL) When you have a pump its £200 to start, you still need men with you all expense! We borrowed two guys from another job at 4:00pm and we were done 4:30pm- We didn’t need laser levels as we were going off existing foundations, not rocket science just simple rules of thumb🙂

Sam tate Pump to expensive, guys dropped down off the other job and in 20 minuets all done at the end of the day them iff home👊 Concrete pump to expensive mate they start at £200

😆

Guessing you're from the states? Don't need rebar in a static footing, as its only the compression we're worried about, not tensile strength

Not on the spec, ground was solid!

👍

Prrrrrppp. Haha 😂. "Gravy check" 😂😂😂. Pissed me self off that comment sir! 😂

2 storey & above

@@irman3105 not at all, it depends on the ground conditions I.e if you have soft spots

Yes its all dependant on the judgment of the local inspector as he sees fit, argue if you disagree ut he will have the final say🤔

tamper, just knock one up out of wood like they have. Quite simple

Liam Crawford It is when its trench filled, the shear volume and with extra water or free flow additive. This was only 225mm depth and barrowed in! Hope that helps!

Tamping takes out air pockets

9” or 225mm

no se por seguro pero creo que no usamos estas cosas en englaterra por mucha casas de familia.

Es normal in españa para casas nuevo?

Usually, 600 wide and 250 deep- we went of the existing foundation

@@foundationgood123 thank you keep the videos up top stuff

Marty Cannon no, because the ground was good see how hard it was digging it!!

The can’t had an hour when they were able to jump on the barrows, saved £500- Some times its swings and roundabouts 🤔

Hi, 450mm

Chris Longhurst in the south east our minimum depth for a single storey extension is about 1200mm 😳

Tgey were 225mm following the existing FBDs! Hope that helps

150mm of "toe" or projection either side of the structure

@@christopherwright1100 he asked for thickness not width

It’s 1 metre plus we’re we are in uk if you don’t hit chalk deeper

Perhaps in the area you build in this is what the ground conditions require but I doubt that unless you only build within a very small geographical location. Who has told you this is what you need? The thickness of the concrete and the depth as which it should go are totally different things. The depth of formation level is important as you need to get down to soil that can easily bear the load of what is to built on top of it, then at that depth you can still use a say 200mm thick foundation if that is what will work, maybe you need 450mm it all depends and should be designed on a building by building approach. Too thick a foundation is just as bad as too small a foundation. Say you put a 600mm wide by 1000mm deep found next to an older house with 600mm by 200mm founds at a depth of 750mm - by pouring this foundation and with the effects of ground heave you could end up with a extension that stays put and the original house moves slightly - you end up with differential movement, cracking and damage - all because the found was too big! A project we are designing just now requires 600mm wide by 200mm deep found at a level of 800mm below ground level, this is perfect as a test pit has revealed this will see the builder down into stiff boulder clay which will have very little water change as it is on a hill with good water run-off. Then onto rebar - it depends on many factors, there is no such thing as a one found fits all buildings situation! Rebar is nor really required in a foundation if the bearing ground is confirmed as highly stable. Also, never assume building control officers actually have a clue about foundations - some do, some don't, also architects usually don't either - this is structural work.

its always best to put the wife in the foundations if find

I did an extension and the footings were only a foot deep.

Bitcoin CEO It took two days due to the hard ground and previous foundation from the conservatory 🤔

@@foundationgood123 class, thanks for that quick reply

You don't want to use any hardcore on foundations. You want the concrete to flow directly onto undisturbed ground at formation level. A found on hardcore is not as good as a found on undisturbed soil. Putting hardcore in relies on someone building it up in layers properly and compacting it. More often than not when hardcore is used incorrectly I see differential settlement where some of it was well compacted and some not - this can be so bad walls will crack and pull away from existing buildings etc. Different story for concrete slab pours where you have a large raft of concrete being poured over a larger area, you want it to sit and "float" on the surface, if the ground is good undisturbed sub-soil that will not have big fluctuations of water content etc. then you don't even need hardcore for a slab. This is why engineers should be involved, and often you should not let a builder just choose for you because often they don't actually fully understand it and go for a 1 size fits all when in fact you can often save time and money and end up with a better finished build if you follow the conditions.

You don’t need hardcore under the foundation concrete you amateur.

Bertie Blue Better removed if possible or use rebar which can be left in!

Hi, It wouldn't but we were working to spec and it wasn't on the plans and the inspectors were happy enough with the hardness of the ground so were we-:)!

Oh, don't tell me you left it up there again...lol

Haha yes, 60cm or 600mm lol 😆

@@foundationgood123 That would have been a painful dig, lol. Excellent video 📹 👏

I was thinking the same. Looks about 200mm - 250mm to me. Chris?

I dont think there planning parking any jumbo jets on the found so think its up to the job guys! :-)

our comments seem fair considering a foundation normally is 1 meter deep for a multi storey car park . Must be very solid ground there.

1 meter deep for a small extension??? not sure where your getting that from? is that real world experience or just google? :-)

doug hay Yahoo

Why hehe

What country is that

@@kierenboimufc5940 a sandy one!

@@Carl-yu6uw 😂😂😂😂😂😂😂👌👌

No it wont. Plenty of old houses build on less footings with no reinforcement. We tend to over engineer buildings now.

@@dorianleakey what about old house that are built straight off of chalk or even a brick spread footing still standing today

Bungle Bons l Leahcubb

Trench is standard 1 metre below ground level but More if ground is a problem, sometimes less if you hit solid ragstone or hard chalk, All down to building inspector. Conrete can be 250 mm thick but more people like myself mass pour the trench to save the poor brickie.

To be honest, there's very few builders taking on new work where I live, and those that do charge a heavy premium to other parts of the country. Some folk have little choice but to have a go themselves.

No maté they’re 225mm they’re the same as the house foundations I did explain this in the video very clearly!!!

@@foundationgood123 appollogies I never heard that 👍

Still too shallow in my opinion tho .
