My mother bought a house next to a bog. Needless to say, with the drainage being almost non-existant, it has started seeping in water, especially during the spring. There has been some exceptionally warm winters in the North of Norway the last few years, but we've also had record snow, so when it thaws, everything goes at once, leading water to saturate the boggy earth, and then to seep into the house. Luckily it can be fixed by digging out new drainage trenches, and filling them with felt and gravel, accordingly, to filter the water out into a small drainage brook nearby. It's still going to cost a fair bit to get it done, though, and proper drainage could have saved us the problem in the first place. Luckily the insurance company will rework the inside, as panels got wet and need dehumidifying and mold-extinction.
