you can get decent underlay materials these days specifically designed for pond liners..
I'd go with a bottom drain setup with a gravity fed system.
Them carp are gonner eat a lot and make a mess.....
did this on my last pond and its the best setup by far....
bit more work involved as you'll have to dig in the filter to sit level with water level etc.
much better than "in pump" setup IMO.
My pond was 12ft x 9ft x 5ft deep , dug in about 6ft with the digger , concrete base installed with bottom drain pipework fitted , blocked up to approx. 1ft above ground and back filled with concrete all round.
Underlayed and linered and never had a problem.
One tip - get the best / biggest filtration system you can afford.
Remember - you can only under-filter but cannot over-filter...

How are those bottom drains to fit chap? I've been roped into helping fit one in the not to distant future and I've never done or even seen one before

easy - just need the confidence to cut a hole in your liner....
they have a bolt on flange - which you remove and then lay the liner over the top with a suitable sealant / adhesive and then bolt the flange back on - then cut the hole....
loads of info / videos on this on youtube which will help
best set up by far IMO - have a slight fall into the drain so all the **** and debris will eventually make its way in there and through the filter....job done.

Thankfully it's not my liner so I won't be doing the cutting! From what I've seen it will be simple enough so all good. They do look a good idea, but I've never seen one in the flesh to see just how it works,but it sounds like they are the best idea for sure

basically - bit more work to install...
but....
all the **** ends up on the bottom of the pond and then into the filter - which is what you want - let the bacteria go to work...
Also - the pump is located at the end of the filter - so easy to maintain etc.
don't forget a properly spec'd UV tube - will help polish and keep the water clear...

I would have a chat with Fawcetts liners, they have everything you could need liner wise. I have their reservoir liner in my pond and it's been there for 15 years with no issues, I think the one I had was guaranteed for 40 years or something.

Yeah definitely concrete the cavity. You could think about using the hollw blocks and filling the cavitys of those too
That sealer is decent stuff, it's what I did that waterfall I showed you with, think they do a coloured version too not just the clear

I'd definitely look at getting a bottom drain it makes cleaning much easier. Also if you're doing a rectangular pond have a look at box weld liners which are made to the shape of your pond so no messy folds in the corners. The other option is to get it professionally fibreglass lined but once you go down this route you'll need to up your budget a bit.
The extreme koi forum has a pond build section and you can get some good ideas here. If you join you can get some excellent advice too..

Can't remember the name of it mate, there's some left though so when I go round there next I will have a look

Only just seen this thread! lol
I build a pond 9 years ago and went through all the same thoughts you have mate.
If you're building a koi pond from scratch you really do want a bottom drain (aerated ideally), gravity fed filtration.
Having pump fed filtration puts your filters on the back foot straight away as any waste is chopped into tiny little bits before it gets to the filter making the filters job much much harder.
Go 5ft deep if you can and as said below get the biggest filter you can.
I was initially going for a box weld liner as mine's a regular shape but decided on fibreglassing in the end. Cost about twice the amount of the liner but I'd got to that stage where I'd spent much more than I'd thought and sod it, I'm only doing it once! lol

G4 pond paint?? Dont use carpet or underlay it could rot and would nulify any warranty on liners. As said get the proper stuff. Each material of pond building has its pros and cons depends what your happy using.

Ever thought about a Denby Koi pond Josh, they make them to suit the size you want you can get a viewing window put in the side if you like and they will fit the bottom drain filter to it might be an option, their FB page shows some after delivery that the clients have finished with whatever their choice of cladding, they will even come and fiberglass one if you build it.

Granted It is a fair bit of dollar if you want a reasonable size a quick way of setting up a pond and I suppose the beauty of it is if you move so can the pond.

A lot of larger ponds are now lined in fibreglass
