you may have a septic system leak or a water main leak
I have a water leak under slab cement down in my basement. It is always damp and dank down there. I can't point out where it's coming from. It seems to be random where the water comes up. What do I do?

without knowing your climate, the best would be a crawl space with a concrete slab.
assuming that it is a waterline leak, i would suggest the alternate route for simplicity sake.
A Pad foundation is just a concrete slab with no foundation walls. They are typically used in the South where this is no or minimal frost lines.
To prevent water from seeping through your foundation slab, you can apply waterproofing sealants or membranes to the exterior of the slab, ensure proper grading and drainage around the foundation, and maintain gutters and downspouts to direct water away from the foundation.
Water coming up through the slab after rain may be due to poor drainage around the foundation, cracks in the slab, or a high water table. This can lead to water seeping through the concrete and causing issues with moisture and potential damage to the structure. It is important to address the underlying cause to prevent further damage and potential mold growth.

I have a water leak under slab concrete and it is coming off the walk into my yard. How do I get to it to fix it without breaking the sidewalk?
To prevent water from seeping through your foundation slab after rain, you can ensure proper grading around your home to direct water away, install a drainage system like French drains, seal any cracks in the foundation, and consider waterproofing the foundation.

The typical thickness of a slab foundation is around 4 to 6 inches.
A slab leak when related to plumbing is generally a pipe leak under the slab (your home's concrete foundation).

As a concrete contractor in Sydney, I’d say 100 mm is generally the practical minimum thickness for a standard residential concrete slab-on-ground. However, the correct slab thickness depends on several factors, including the soil classification, house design, loads, reinforcement requirements and footing system. In Sydney, some homes may require thickened sections, edge beams or engineered footing designs, particularly on reactive clay soils or for heavier construction. The National Construction Code requires residential footings and slabs to comply with relevant standards such as AS 2870, while NSW also has specific requirements for slab construction. For any new house foundation, I recommend getting a proper soil test and engineered slab design rather than choosing a thickness based on a general rule.
A slab is cheaper to build than a basement. The basement will give more space but is more likely to leak and more can go wrong.

The recommended concrete slab thickness for a house foundation is typically 4 inches to 6 inches.
