In-ground pools should be designed to withstand the soil pressure on the sides and
bottoms. They may be built of
cast-in-place concrete, concrete sprayed onto a steel, reinforcing frame (gunite), vinyl liner on a structural frame, or fiberglass shell. sand
or earth bottoms are generally not acceptable. Hairline cracks in concrete or fiberglass and small tears in vinyl may
be repaired in most cases. Lowering the water level below the crack or tear is
usually necessary. Large cracks may be
serious, indicating soil movement or inadequate drainage. Professional advice should be sought.
Concrete
pools should be painted every 3-5 years and re-plastered (Marcite) at 10-15 year
intervals. Fiberglass may be patched,
recoated, or covered with epoxy paint.
