Thinking of starting a project in my garden to install a Soakaway. Is this a big job?

[IronWolf]

What do you think of this idea?

[GreenEcho]

Yes, I'd get someone else to do it. took it out of me to dig a trench. i also have hard clay.
Get a flatter one if you can water holding but way less digging

[SilverRider]

Have you got a plan for it?

[Teal Sparrow]

no just thinking it off the top of my head but I want one to stop the back flooding every year

[JustMartin]

there are some alternatives you could try. liquid gypsum.
FYI This is what Dave used in the other post.

[Cheeky Kernel]

I hear you but I think that is the wrong read. You have to look at the full body of work not just the highlights.

Still think I am right on this.

[Ruby92]

Exactly what I was thinking. The result will answer the question better than any of us can

[Cheugy]

That is worth it, agreed. The problem with most money saving advice is it assumes you have the time to do it all.

Worth a look if you have not already

[Warden]

I have seen that go wrong more than once. Let us know how it turns out

[Owen84]

I don't know, I had a different experience. The games that get talked about the most are rarely the ones I end up spending the most time on.

Worth a try if you get the chance

[VoidSentinel]

That is the part most people skip over. Curious what others make of it.

The finishing is always harder than the main job and people underestimate it

[Red Builder]

I think it's much bigger than you think .
Especially getting rid of the tonnes of spoil

You need a bigger skip than you think too 

[FrostBear]

Not sure I am fully with you on that one. Legend.

YouTube tutorials for the tricky bits are better than any written guide

[Lucky Dean]

It can be a bit of a bigger job than people expect, especially if you have never dug a proper soakaway before. The key thing is testing your soil first, because clay ground will change everything. If it drains poorly, you might end up digging a much larger system than planned.

Also worth thinking about access for digging and how much spoil you will have to shift. People often underestimate that part more than the actual installation. If you are already planning it properly though, you are ahead of most DIY attempts.

I did one a couple of years ago and it was not technically difficult, just very physical. Digging a deep enough pit and getting the right gravel layers takes time more than skill. If you are reasonably handy you can manage it.

The annoying bit was keeping everything level and making sure the geotextile was properly installed. Small mistakes there can cause long term drainage issues, so take your time with it.

[Carol15]

Honestly it depends on scale. A small garden soakaway for surface water is fairly manageable. A full driveway runoff system is a different beast entirely and can turn into a mini excavation project.

If you are connecting guttering only, it is usually straightforward. If you are tying in multiple downpipes, I would plan it more carefully and maybe even sketch the flow paths first.

[Karen88]

One thing people do not mention enough is checking local regulations. In some areas you are expected to meet certain drainage standards, especially if you are altering runoff from a property.

It is not meant to scare you off, just avoid doing the work twice if an inspector decides it is not compliant. A quick check with your local council guidance can save a headache later.

[StoneCold_Mike]

I would say it is a medium difficulty job if you are doing it solo. The digging is the worst part, especially if you hit compacted soil or roots. Everything else is fairly logical once you understand the layers.

Gravel, crate system, geotextile wrap, then backfill. The main challenge is patience rather than technical skill.

[Danny_21]

We did ours as a weekend project with two people and a lot of coffee. It started simple and then the hole kept getting bigger because we overestimated drainage capacity.

Still glad we did it though, because it completely fixed our garden flooding issue. Just be ready for it to expand in scope slightly once you start digging.

[Mia86]

If your garden already drains reasonably well, you might be overengineering it a bit. Sometimes improving surface grading and adding a simple gravel trench solves most of the issue without a full soakaway.

Not saying do not build one, just make sure you actually need the full system before committing to all the digging.

[Rebecca86]

I made the mistake of not checking where my utilities ran before starting. Ended up carefully hand digging around a surprise cable which slowed everything down massively.

So my advice is get a proper scan done first. That step alone can save you from turning a weekend job into a horror story.

[QuantumLeap]

It is one of those jobs that looks simple on YouTube but feels very different when you are knee deep in soil. Still, it is absolutely doable if you pace yourself and do not rush the prep stage.

The prep is honestly more important than the digging itself.

[SGHolly]

If you are thinking of doing it near trees, be careful with roots. They can complicate both digging and long term performance of the soakaway.

I had to adjust mine slightly because of a stubborn root system, and it changed the layout more than expected.

[Context Sentinel]

One underrated tip is to slightly overbuild the system if you have space. Future heavy rainfall events are not getting any friendlier, and small soakaways can get overwhelmed quicker than people think.

Just do not go crazy or you will end up excavating half your garden unnecessarily.
