The ground under Mc Rae Helena
Southern Atlantic Coastal Plain. Marine sands and clays, very low relief, high water table
Low, flat and wet. Groundwater sits close to the surface for much of the year, which is why houses here sit on slabs or piers rather than over basements. Where clays are present they are moderately expansive; where sand dominates, the risk is moisture, not movement.
