Generally highly plastic clays, and sandy clays
are present in these areas. These clays can
experience significant shrink and swell
movements. The foundations must be designed
for this condition. Parts of Cinco Ranch has a
surficial layer of sands, underlain by expansive
clays. The foundations these soils should be
designed, assuming a perched water table
condition.
Highly expansive clays, drilled footings are the
preferred foundations system. Soft soils are
observed in some lots. The soils in the River
Oaks area are generally moderately-expansive.
Moderately expansive sandy clays, clays, and
sands. Special foundations must be used for
structures near ravines. Look for faults.
Very sandy soils in some areas, variable soil
conditions. Slab-at-Grade is a typical
foundation; sometimes piers. Shallow water
table at Oyster Creek. Highly expansive soils
in parts of Weston Lakes.
Highly expansive clays on top of loose silts and
sands. Variable soil conditions. A floating slab
is a typical foundation. Piers can also be used
at some locations. Soft in some lots. Shallow
water table.
