I have water coming through the walls of my downstairs room - through the mortar, and also up through the concrete floor, leaching salt out. A bit about my layout, excuse my naive terminology - I just flush em, I don't fix em.
My block slopes from the road frontage down to the back. The back of the house has a split level with a rumpus room underneath. Along one side of the room, the ground level is about 1.5 metres above the room's floor at the highest point. Along this side, a previous owner looks to have dug it out, probably laid ag pipe, and backfilled with broken tiles etc. Then a layer of soil (clay), then a layer of large scoria. This room was an extension, there's also an old under the house room further under the house. When it rains heavily, water enters at two points (soon after the rain starts) - at each corner of the room closest to the old-under-the-house-room. Through the brick mortar.
Our block doesn't have a stormwater drain. Just at the back of this rumpus room we have a pit with a float valve operated pump. This pumps water straight onto the back lawn, towards the lowest level corner. I believe a previous owner has dug soak pits (is that what they're called?) in that corner. I haven't dug them up to look, but there's bits of concrete, steel offcuts and broken tiles poking through the lawn in spots. Also, I know from a neighbour that the last owner laid ag pipe across the front of the house, along a garden bed.
My feeling is that the basic problem is the groundwater level goes up quickly when it rains, and the block, despite some good intentions, doesn't get rid of it fast enough. It looks like a fair amount of plumbing has been done here in the past, and I don't really want to get burnt (aside from the fact that I bought the place, but that's water under the bridge)
Sorry to be so lengthy. My basic questions are is the groundwater thing the likely problem? What kind of solutions should I be looking at? I'm thinking of digging one hell of a deep drain all the way around the front of the block, but I don't think the wife will agree with an open channel
Any responses would be greatly appreciated, here or at firstname.lastname@example.org
