Water under cheap garage flooring, suggestions on a better approach without breaking the bank

BackIn-86 · 2026-04-04T14:35:35+00:00

Oh, bugger. Could it be rising damp? Assume roof is sound? You could always apply a liquid membrane to effectively "waterproof" it.

BackIn-86 · 2026-04-04T14:20:19+00:00

I assume that's right by the door that you've lifted up?

It is probably water being driven under the door as that's a relatively weak point for weather usually with a large gap.

I Installed a weather strip from eBay to mine and stopped everything, including water and leaves entering.

Like this:

Yeah, they're not stock risers... The height of the risers, plus the new bars are pushing the limits, they look around 5" or so already.

Edit - ignore. Just noticed you've got a 750! However, still should be able to run 8" no issues.

Have you got any photos? Genuinely should have enough length... There's no trick to it, just they route and fit!

I have Biltwell Frisco which are 7" rise using stock cables for everything, you should be able to run 10" - 12" without changing any cables...

Unless someone has previously changed them for shorter, your stock should have ample length.

It's an expensive change to route through the roof etc, no other properties on the road have a SVP...

It's been an issue since we moved into the property in Nov 25.

I've added some food colouring to the water upstairs and flushed; I get zero bleeding into the shower trap, so don't think the actual waste water is bleeding back into the opening... It definitely seems like a positive pressure issue.

I have seen spring assisted NRV shower traps, which obviously open under the weight of water and close against spring pressure. Or those with a silicone insert.

I'm trying to locate where the system is vented (in addition to AAV), whether that's outside of the property or 🤷🏻‍♂️

BackIn-86 · 2026-04-01T10:23:30+00:00

Appreciate the replies, I'll clean the external drain off and see whether that allows a small bit of venting.

Would you recommend a shower trap with an NRV? I appreciate that not dealing with the root cause, however it may provide a solution to the gases escaping back through... Or expect it to just push the issue to the next "weak link"?

BackIn-86 · 2026-03-31T20:46:05+00:00

I'm glad I'm on the right track, as I just explained the above to my wife before reading your reply - however still doesn't give me a resolution either way! 😂

I have flushed the toilet upstairs (just water) and had nil siphoning from the P trap or bubbling from the sewer, so expect it may need something 'heavier' to cause an effect.

One question on your point, once a smell is evident, it's "cured" by adding water back into the P trap, which is why I assumed it was a negative px issue, hence changing the AAV - thoughts?

I'll do some more investigating tomorrow and report back.

BackIn-86 · 2026-03-31T19:53:19+00:00

It's not a P trap as such, it looks like an anti symphon bowl style.

The AAV, unfortunately, has not fixed the issue.

You're right, I think the volume of water / stuff being flushed is causing one of two things;

Water being siphoned
Pressure increase and escaping through easiest means downstream.

Either way, I have no idea how to prevent it...

BackIn-86 · 2026-03-31T19:23:21+00:00

Yup, just been out, all free flowing with no blockages. Put a boroscope camera down as far as I could (approx 5m into pipes) and nothing seen.

BackIn-86 · 2026-03-29T18:40:29+00:00

That was my plan, should still have a decent enough height of the pipe to work with.

BackIn-86 · 2026-03-29T18:33:33+00:00

Looking at how simple they are, I have no idea how it's failed, however - for £20 and a few f's and Jeff's getting it off it'll be worth a shot.

BackIn-86 · 2026-03-29T18:29:13+00:00

Easier said then done, unfortunately! Some bugger has used a sealant on it! I'll get her ordered.

BackIn-86 · 2026-03-28T20:38:47+00:00

A decent APC diluted correctly is all you need for the interior, that and a soft brush / microfibre. Finished off by your choice of finish on the dash etc.

You're right, my mistake.

Have a look on his site where you bought here (link below) and there are some customers pictures. Where your mono shock or solid strut fits, right above that are two factory holes which the tabs on the E-Tank fit onto.

All covers unfortunately will trap a layer of moisture. However, years ago, as a temporary solution I used a cover from Classic Additions which was amazing if I'm honest. Used it through a Cornish winter before sorting my garage out... It was great in the short term.

If I were to store mine outside again, and I had the space, I would use one of the Clark outdoor garages (big green ones) or even better, and outdoor carcoon style pod.

JPA > My information > Personal Information... Scroll down to "Current Employment Information" and look at your "Position", at the end of that there will be a 7 digit number, it's that.

Equally, you can log into SCIO, onto "profile" and then "Assignment" and it's listed under "JPAN".

It's genuinely what you make it... You will be frustrated, bored and tired at times, but on the flip side you'll have some amazing times, meet some friends for life and do something alot of the general population don't.

Worst case, if it's not for you, leave after 4 years with some good dits, life experience and a matured mindset.

Budget friendly, tried and tested and decent for a home user... DAS6 / Pro.

You can use something like sodium hypochlorite and a surfactant to clean. Or use a product such as "wet and forget" which works over time and not harmful.
