On of the most dangerous location of leak is on the foundation, as it can endanger the integrity of the building. A building with weak foundation can be threatened by sudden collapse. Especially if we consider the fact that slab leak can happen without knowledge due to the lack of signs and if there are signs, they can be quite subtle which make them left unnoticed.
Obviously, the best way to do is to ask your contractor to check your piping, especially on spring, as pipes integrity can be stressed during a cold winter. You should know the normal water volume of your pipes, when there is a sudden drop in water output, you may have a leak somewhere.
If your pipes are leaking, your only solution is to have them fixed, the best thing to do is to get an expert that have a good experience in repairing the leak without destroying too many slabs. During house construction, make sure that all pipes are assembled correctly and tightly. The cuts should be straight and clean to prevent unnecessary leaks. If you are living in an area with many earthquakes, then you may need an extra strong piping network to withstand sudden vibrations. If the soil in your location is unstable, even there is no earthquake, the foundation may shift and move which put some pressure on the pipes. So it may be necessary to fully strengthen the foundation to compensate for the unstable soil condition. These are things to consider when building your home, to prevent future slab leak problems.
