High-Water-Table Excavation for Pinellas Paver Bases
Coastal Pinellas lots often hit groundwater a foot or two below existing grade, especially after summer rains or a king-tide week. If you excavate a deep section and the hole fills, compacting in standing water just pumps fines and leaves a soft base.
How we handle it
We schedule the undercut for a drier window, dewater with a pump only long enough to place geotextile and the first open-graded or dense-graded lift, then compact in thin passes. On organic pockets we undercut to sand or use a cement-stabilized lift rather than stacking more dirty fill.
A high water table is also a drainage problem. The finished field still needs a two-percent pitch and a place for water to leave. Permeable sections or a dry well only work when the receiving soil can take the volume.
What not to do
Do not bury filter fabric as a bathtub with no outlet. Do not compact saturated muck and call it a base. And do not set the finished paver elevation below the seasonal high water if the joints will pump.
