4 years ago or so we decided to hook up to municipal water.
My house is a split level with a walk out basement. The water pipe
ran under the front lawn on the side of the house with the walk out
The pipe was brought into the house from under the basement floor
(towards the front end of the house). I think they sealed the hole in
the floor , around the pipe, with concrete. At least that's what it
looks like to me.
Right next to the basement wall the outside ground is about 3 feet
high or so, and slopes down to basement floor level over several
feet. So when they laid the pipe, they didn't have to go much under
the basement floor level.
The problem is when we get long heavy rains. The water pressure
under the house is forcing water up thru the floor; it comes in around
the water pipe. It kind of just slowly seeps up and then just slowly
spreads itself across the basement floor.
I don't know if the area around the pipe was improperly sealed & I'm
quite hesitsant to try and break the floor around the pipe for fear of
damaging the pipe.
I was wondering about relieving the pressure under the floor. Maybe
I could dig out the sloping ground outside, where the water pipe comes
in, down the where the ground is level with the basement floor and
maybe lay a small PVC pipe that would extend out to where the sloping
ground stops sloping. I was wondering if something like this would
allow water building up under the basement floor to push thru the pipe
and just empty out onto the lawn.
Any ideas/comments would be appreciated
