New to the forum and I am at wits end after building ineffective french drain today, plus no builder or plumber having a clue what to do. So let's try the Wisdom of the Crowd!
We built half a dozen years ago, on a paddock, that sits on the top of the hill and gently slopes down. The house is built to look like an old house. It sits on stumps and has a concrete footing around the outside, on which sits a perimeter of bricks. Above that, weatherboard. There is limited crawl speace underneath. The ground is clay.
Water pools against the brick footings along the east and western sides and especially the southern side. By the end of summer, the ground under bedroom 1 is still damp and there is still water pooled along the brickwork. I can say for sure, there is ample underfloor ventialtion.
This weekend I dug and trench along this southern and western wall (along ensuite and playroom), the ground sloping towards the south so it was easy to get a fall. Sure, some water (about half a litre) pooled but nothing really changed inside. I can still see water pooled the entire length of the southern walls (ie along hallway 3, 2 study, living room).
Things we have ruled out
1. It's not the water table or a spring. We built in winter, and dug some big holes for septic, the chimney etc and nothing filled with water. None of the footings did. The stumps which are set in concrete, sit below the soil level and do not get water in them.
2. Every pipe has been checked by professionals and mself getting under the crawl space looking for leaks, including waste water. The water is also seasonal - there's never any around the Living Room in summer for example.
3. its not water running towards the front (north) of the house although the ground does slightly slope this way. I have dug deep explarotory holes there and the soil is pretty dry.
1. Water run off the side of the building, pooling on the concrete footing which extends out a touch from the bichkwork, the water then seeping back in. Our gutters do leak clog up and spill over a fair bit too, we are rubbish at clearing them.
2. Garden beds mulched, leading to the above - the soil is wet. The beds are brick edged - do they trap water which then seeps back? (this would only count for the courtyard.
4. Water blowing into the air vents. Some vents are at grounds level - does water run into them during heavy rain? (basically lawns and landscaping should have been lower or the brickwork higher)
We have checked most stormwater pipes and joins, and I have measured water in and water out volumes looking for a difference and therefore a possible subteranean leak but this would have to occur on most pipes, which is unlikely.
So.....the million dollar question....has anyone else had something like this? I will take any suggestions too!
At this point the goal is to extract the water because I'm not confident we will ever know the source (6 years of trying) - can we get some sort of drainage holes in the brickwork to let the water out? I figure we may never work out where it's getting in but if it can drain away, I don't care. One issue would be the ground inside dips to at least the concrete footings, thereby making holes in the bricks less effective as the water level isn't as high but in some places it would work.

First thing is to get a professional plumber to check your pipes for a leak.
It looks to me that water maybe entering under your house from the front yard lawn area
another possibility is the water tanks over flow long the side of the house.
The water appearing along the back wall on the outside may be seeping up from
the water ponding up against the rear wall on the inside under your floor.
