Waterlogging in basement
So I recently moved house, and I'm setting up my workshop in the basement, but there is a bit of a water problem. The water table in the area is high, and the basement is about halfway below the surface of the ground, so whenever it rains a lot, the place turns into an indoor wading pool. The water seems to have even come almost a foot up, judging by the stains on the walls.
The plumbing here was done a bit poorly, A sump was dug right under the room, and ground water leaks into it and into the room through the trapdoor, flooding it. In order to rectify this, the owners decided to make another sump, and have a small motor pump water out of that sump into a gutter outside. So if the first groundwater sump overflows, then the water drains into the second sump, from where it is pumped outside into a gutter.
I'm not certain how effective the second sump system is, since it was built after the foot high flooding, and I haven't seen it at work.
Is there any system I can build to help contain and prevent the flooding? and any methods of waterproofing my storage cabinets and drawers? I can't do any permanent or major modifications to the room, as this is only a temporary arrangement.
Thank you for taking the time,
