New garage questions

[gaz1]

this is something worth thinking about

also worth it

You're moving too quickly - I've detected mission-creep now

'Tis going to be an ordinary shed/garage.

 

[Misterg]

Thanks for the suggestions and advice so far.

Next question: What do I do with rain water?

There's no convenient drain, and we have previously tried to dig a soakaway in this general vicinity, but ended up with a big clay pit with no bottom in sight. Can I just let it run off into the stoned area next to the base? (I'd probably fit gutters to stop water staining, etc.)

If you have (or are planning) a garden path then you could maybe hide a soakaway under the path...that's what we did (removed 8 yards of mud!). We're London clay but on a hill so it slowly drains down the hill.

 

[gaz1]

with a soak away it depends on what is around

Drainage - Soakaways

sometimes finding the drain is the best coarse of action but you have to know your runs to see if its fesable

makes me laugh having a soakaway .dig a 6 foot hole and fill with gravel and wot happens . it fills with water and overflows i have a pit in my garage and it fills with water about a foot from the top it only ever drops another 6 inch in dry weather thats where the water table is so if it was filled with gravel it would still be the same height

Works when done correctly with the right conditions.

I remember picking an item up from an ebay seller...in his back garden he'd dug a huge hole (in clay) which was full of water. Turned out it was meant to be a soakaway...in clay I think it's called a pond

which is very rare. they put land drains in the playing fields at back of my house witch is the same height as my garden it always flooded . i told them its a joke but who am i to tell the experts it still floods and will carry on doing so my land drain goes in to the man hole drain leading to the septic tank i was going to put the pipe over to there field till i put my water levels on and theres no fall its the same height

I run mine into a large water butt from gutter at rear it acts as a buffer, it then has a long hose that redistributes the water away from the garage, it's outlet is constantly open, it's never overflowed.

I guy built a garage near me, he went through planning permission for a garage with steep pitched roof to allow for storage space above the garage (), when he had built it he decided to only floor part of the roof space, the un-floored part sits nicely above he's vehicle lift..... what a shame.....

4 inches of mot under the slab is that ok?
I did my own groundwork for my slab and had 8 inches under the slab as that was what was recommended by the concrete company, though my slab was 6 inches with C40 with fibres as I didn’t want re-bar to cause problems for the mounting of my 2 post lift.
Fibres in the concrete should be fine, I’ve had no issues with cracking on mine 5 years on, but I’m not a builder!

Id be inclined to do more than 4” too. But it depends on your ground conditions. Mines about 6 inches at one end bit more at the other. Then a 6 inch slab with fibres too.

I dont understand this fear of planning. Just apply and build what you want. Im national park so have no choice. If what you want is sensible, it wont be a problem.

Have you considered timber?

 

[Misterg]

I dont understand this fear of planning.

It's building regs that would kick in - again, not too onerous, but hassle I'd prefer to do without.

Have you considered timber?

I have, but I'd like to build close to my boundary (<1m) so needs to be 'non-combustible'.

put ibcs down the sides to collect water and slowly drain them into the ground is what id do

so plan for them being used as you can use the ibcs and also a french drain but in summer the ibcs can be used to water the garden

then you can go out and buy some ladies half leg tights

this can be used with a french drain as an aid to the system in water collection and slow draining of the system

Thank you again - still working through all the previous threads / videos!

Yes, I can put a couple of water butts alongside and do it that way.

Have pretty much decided that I'll get a pre-fab.

Thanks all.

with an apex roof you can run a pipe down the back of the garage and fill just one side up where your ibcs are as well as with the twin stacked system you may have to dig into the ground so you can fit a 4 ibc system or even up it to 8 ibc tanks on the top side of your pic

remember this is a water collection system to acompany a land drain also a good aproach when dealing with clay areas

Ground at mine is pretty stable it's mostly building ruble that was dumped from what ever was there before our house.

I went for 6 sub base and 4 concrete C30 with fibers, plasticiser and mesh, I set in some bolting down points for things that you don't want easily removed in the night....


I know you can apply for planning but it is cost and hassle that's not always needed, had our neighbour objected to 24ft of garage right on the border I'm not sure I would have been allowed one at all.

Our garden already sits 3ft above next doors I'm pretty sure it would have been rejected, as it is I'm within all allowed permitted development rules. I had to build a retaining wall and replace the full fence which wasn't mine, when I started digging out it became clear it was just going to fall over.

I have a Compton's concrete prefab. It was put up in 2 days...very impressive....it's also around 30sqm.

As long as the base is above the ground it'll be dry.Mine has the apex roof which is done with steel trusses. My roof is "tile effect" steel which still looks good (been up about 14 years).

I ply lined and insulated mine...very easy to do off the bolts which hold the panels together.
