Landscaping - Swimming pool removal?

[PermaChanged]

Right, time to think about hardcore (nice) and concrete in preparation for full patio!

I've heard that using fibre infused concrete is perfectly strong enough for this purpose, and works out far cheaper than using regular concrete and with rebar - yes it's a more expensive mix but far less man hours required (even if they're my own) in laying and tying rebar framework and mesh.

Can anyone clarify whether fibre infused concrete without any rebar would be fit for purpose?

What do you need concrete for when laying a patio?

This makes a lot of sense.



100a was number plucked when looking through consumer units in general - something like this https://www.screwfix.com/p/british-...way-populated-main-switch-consumer-unit/4274x likely won't be drawing anywhere close to it - the only thing I know for certain will be run from the sockets is a beer fridge!



The 5kw is the input for 21kw output of pool heating.

How does it output more power than you put in?

I was under the impression a 4 inch layer of hardcore followed by a 4 inch layer of concrete is the ideal bed for a porcelain patio, as advised by the guys who performed the pool renovation. It's porcelain slabs to be laid, does that make the difference, or the fact it's around a pool? I really don't know the "why?"!

Witchcraft and wizardry. In layman's terms it's been explained to me that they transfer heat rather than generate it, which is how they're so efficient - they're basically reverse fridges.

Yes porcelain has to be laid on concrete. Fibre Reinforcing is normally used to add strength to the concrete itself but it wont prevent your substrate (MOT / Hardcore / Crusher-run) moving or settling, its important that this is well consolidated (whackered) before the concrete is poured. Fibre is often added to shot-crete / spray-crete to improve its overall strength. Yes it can replace rebar to offer similar strength concrete BUT it is important that the fibres are added slowly to the concrete mix to ensure good distribution of the fibre and to prevent clumping. Its much quicker to lay but cost-wise it costs similar to re-bar.

A heat pump doesn’t create heat, it moves it from one place to another. Air conditioning and fridges are all heat pump systems.

Strictly speaking it’s a coefficient of performance and not ‘efficiency’ as it’s not generating heat, the heat already exists in the air/ground/water (what ever you are using as the source).

For every one unit of energy in, the system can move typically 2-4 units of energy in the form of heat. In the case of the op, it’s taking the heat from the air and putting into the water.

There is heat energy all around us, even when it is very cold. A heat pump captures that heat, compresses it to increase its temperature and then releases it into what ever you want to heat up.

A fridge or air conditioning is that process working in reverse, moving heat out instead of in.

Makes sense.

Suppose I should post an update really.... so much for this being titled "swimming pool removal"!!

So since last update we've had hardcore laid and consolidated, outer walls chased and trunking with lighting cable placed throughout, concrete laid, walls scratch coated and ready for finishing render.

Should get our first swim in this coming weekend!

Wow what a difference it's a huge space with a pool in it now!

Perfect weather for a dip

I still don't get it...

...now I do!

So cool. When is the OCUK bikini party wine mixer?

 

[Deleted member 77746]

It's like a little mini plunge pool

 

[PermaChanged]

15ft x 30ft is a little bigger than a plunge pool, and should be able to accommodate all the OcUK bikini wearers no problem

Here's a few more pics of the process of how we got to that stage;





Boundary fence posts/wall



Hardcore going in



Walls chased



Shuttering in





Concrete going in



Walls getting scratch coated

We finally held a pool party!

Since last update the walls have been rendered, painted and fence panels have been installed. Our party shed was moved up to the concrete pad (temporarily, until all the porcelains are laid) and an awesome time was had by all - all of the effort finally felt worthwhile and we're chuffed to bits with how it's turned out so far

really really nice

 

[danlightbulb]

Right decision to keep pool surely.

Not sure about massive concrete pad though - I would have gone slabbed patio or wooden decking intertwined with lots of planting and/or grassed areas.
