There is retained water under my house slab foundation (no basement). The moisture from this water caused some damage to the hardwood floor that caused me to dig up and see what the issue was. The water level is just below the waste water line and it appears to be present in the waste water line area only where the soil is relatively soft.
It is not supply water or waste water... it is most likely rain water from oversaturated lawn. Although the house is one of the highest in the subdivision, the lawn does not have a good gradient in some areas.
As a fix, I am thinking of putting french drain in the lawn. But how to remove the existing water from under the slab? Is slump pump a good option?

If possible you may want to consider drainage lines with perforated pipe leading away from the building
The make like a mesh fabric that you put around the perf pipe to act like a filter to keep the pipe clean.
we have a similar problem with a concrete slab foundation in Florida. water surfaces up through the floors inside the home. through the carpet and under the tile. We discovered this when pulling up tiles on the floor. water was under the tile. we had a leak detection service come in and they did not find a leaking pipe, etc. our property is flat and the grade is flat. we live near a small lake and this area is known for issues with water intrusion. how do you waterproof the concrete slab? from the inside with a sealer? or french drains outside?
