Diy raft

When you see it done like that, it makes you realise why people use block and beam.

 

I don't think this was really DIY

[JohnMo]

Must say looked good, but a lot of work, but all by hand - not a digger in sight.

Depends on your circumstances, there are those that are time poor and have funds to pay for block and beam and those with plenty of time and short on funds.

Why not? He did it himself.   From Cambridge dictionary.

Just looked to competent.

I suspect he does it for a living.

So when Jeff Bezos went to the edge of the atmosphere with William Shatner, they went in a DIY rocket.

Whether he does or does not is not the point, nothing there requires taught skills, just be able to follow directions.

Well like you I “suspect “ he didn’t do any of the physical work himself 🤷‍♂️

 

the only thing I didn’t understand (or did I miss it?) was the buried metal strap around the outside 🤷‍♂️.  Earth?

[ProDave]

And he started with a nice flat site with ground that already looked hard and stable (what pre preparation was done?)

 

Now try that on our sloping site with an over thick layer of soft top soil containing vegitation?

 

One good thing on there, he glues some sort of cement board to the upstand outer edges.  that solves the often asked question on here how to protect them after a whole house has been built but still nothing covering the EPS upstands.

 

What was that buried flat metal strip around the perimiter for?

Yes not all sites qualify I guess so block and beam have their place.

Yes? Any takers.

It's an electrical ground, in theory a better connection than an earth rod.

As the ground looked like sand, increasing the area probably makes sense.

Makes sense, however having dealt with earth potential in a previous job it was established that depth and ground water content made a huge difference. That strip in dry crushed stone goes against the lessons I learnt in my previous job.

As a 'diy' job, whether he is fully compliant who knows. I just know in Europe it is fairly common to use the rebar in an uninsulated slab as a an earth which is obviously not going to work with an insulated slab and this is used as the alternative.

I hammered my earth spike for the battery (in sand) got to about 20m deep before it passed the test.

In my back garden, go down 0.3m and I hit granite boulders.

 

Occasionally, a sycamore sapling will grow more than a few millimetres, maybe that is the place to knock an earth rod in.

Till you hit the next granite boulder. Getting a decent earth near you must be difficult.

Probably relying on leaking wet underfloor heating somewhere to keep resistance low.

The top layer of steel looks awfully close to the surface compared to ours
