My custom pool design

Re: My custom pool design

Hi @ProjectPete

What are your soil type conditions... is it Class M?

Are you still going down the reinforced Masonry blockwork pool structure + Liner path or concrete shell?

You will need Planning Drawings  & Building/Engineering

Please leave a PM if you require assistance 

Cheers

Chris

Re: My custom pool design

@BIM_Engineer I got this response:

 

Existing ground surface of this lot was around RL8.5m. Historical maximum groundwater level is RL8m.
 
Given the lot is at RL11.24, there is around 3m clearance to historical max groundwater. Depending on time of year the clearance to actual groundwater may be more.
 
With regards to clay, reviewing the closest borehole by Douglas Partners, there was sand to a depth of at least 2.5m below existing ground surface.

Re: My custom pool design

So your water level is approx.3m below the ground level

and the deepest end of your pool is 2.1m

Therefore .9m above ground water.. hydrostatic water pressure maybe an issue..more reason not to use pool liners

Also check your storm water disposal.

Re: My custom pool design

@BIM_Engineer I think we may bring the depth back to 1.7-1.8m (plus thickness of precast slab). Would that be worthwhile?

 

By 'pool liner' you mean the internal finish, right? If so, please remind me why. Risk of bubbling or something from ground water/moisture?

 

Any other things to consider base don the engineer's info above?

Re: My custom pool design

Quick update on this one...

- Engineer's CAD finalised so it's off to a drafty to detail each panel ready for construction.
- Digger, crane and rigger all lined up and ready to go.
- Just waiting on building permit approval which is taking a bit longer than expected as I want to get closer to the boundary than standard so need further certification from my engineer.
- We'll have a combo of aggregate concrete and composite decking around the pool with an aggregate infinity edge.
- We planned to install a custom pool fence/barrier but because it hasn't been certified against Australian Standard yet, my strict timeline won't allow for the design/review/certification/etc process which will be especially painful if it doesn't end up being certified/approved so we're sticking with glass panels, black spigots.

Will def share pics of the install process once I have them in the coming weeks

Re: My custom pool design

It's been a crazy week getting my chemical grout injection (CGI) done, hole dug, base formed and poured in situ, precast panels made and installed.

And this week it's all about getting the concrete poured around the pool, the glass fence in and the surrounding fake grass. The pool area itself will consist of concrete and decking as we push for different textures and dimensions, keeping things as raw as possible.

Re: My custom pool design

Wow, exciting. What kind of decking are you going for?

Re: My custom pool design

Thanks @Kermit  - still plenty to do but at least i can see it coming together now 

 

Jarrah decking along two sides of the pool and it'll make the lid for the underground pump/filter/etc enclosure. I also want to build the lid up a bit so it doubles as a platofmr to jump in from. Will be putting some hydraulic struts in to make lifting the lid nice and easy.
