Thread: Where is the water coming from - Help

I have no real idea about plumbing, especially in older houses, but is there any way it is storm water? By your description, if it only happens when it rains, there could be three things happening. Either the pipes themselves are being used for storm-water, there is a storm-water pipe near-by that is leaking, or the storm-water is getting under the house and it looks as though the pipes are leaking.

Sorry, I'm not much help, hopefully someone will come along soon with the right answers.

The pipes are old salt glazed sewer pipes.

You are going crazy! No, actually, you have it a bit backwards. The tree roots are not channeling the water, but the water is attracting the tree roots. Trees will find water anywhere it runs. Look elsewhere for your problems.

Not enough info for a definitive answer as to where it is coming from, but it ain't the tree roots.

thanks all i guess the only way will be to continue digging back and track where the water is coming from. does anyone know a good structural eng in the melbourne (richmond) area as i need to get some caculations done prior to further digging

Is the water coming in from the high side of the property? Friend of mine has the same problem and it's from water seeping through the ground especially after rain.

The only way to fix his problem is to dig some trench outside along the wall and put some agi drainage in to take the water away before it seeps through.

sometimes water can float right across the top of clay, time, how compact it is ..etc all play a part ......I would suggest running agi pipe along the side of the house and away from that area ....removing the clay that you did altered its normal course .....so now your going to have to provide another for it to run off ....

What's the shape of the ground around the house? Ground should slope away from the house on all sides, including the uphill side. I had a similar problem; uphill side sloped down to the house, thanks to idjit builder. I excavated that side, and built a retaining wall at the property line with a gravel and filter cloth backfill, and a drain pipe at the bottom of the wall.

the block is 15m wide 25m long and points north south with the front of the house facing south, we are just about on top of a hill with the block sloping from south to north and droping gradually by about 1 to 1.5m. the front except for a small garden bed is all cement so to is the drive way down one side (except for another garden bed) and the other side is next doors driveway which is also cement.

the actual water is coming out about 2m from the back of the house right in the centre, the rest of the house is dry clay and very dusty on top, the front half of the house (old victorian) is on solid bluestone footings and the rear on brick footings. there is no water pooling anywhere else and i cant find any evidence of dampness anywhere else.

I think i might keep digging and see what i find and put in a wet sump along the way unitl i resolve the problem.

i just need to get an structural guy in to check the footings and give me some caculations
