This is how hydrostatic pressure causes problems in parking lots. Below, you will notice water seeping from cracks from this asphalt parking lot. This is caused usually from underground water sources. Sometimes these cracks will see water for days or weeks on end. There are even cracks that never stopped leaking water when a sever hydrostatic pressure problem exists.
Hydrostatic pressure can cause extended damage to asphalt pavement. To rectify the situation French drains must be installed and routed to either storm drains or daylight to ground that is lower in order to relieve the pressure underneath the pavement.
