That sucks. Do your neighbours have similar issues??My wife actually just had some work done on the outside; long story short, plumbers dug some trenches, and installed a drainage system.
But the same room keeps flooding.
I think there are a number of factors - the soil is packed with clay, so the water has no place to go, and it pools, and seeps into the house.
And there is no natural slope, so the water cannot naturally drain away.
The flooding is not as bad as it once was, so the plumbers' work made it a little better - but it still sucks that when it rains heavily, I know I'm going to get flooded.
