Water seepage occurs in basements when groundwater has no place to go and seeps from the ground into basement walls and floors. The H03 homeownerâs policy does not cover water seepage as it is considered a maintenance problem. Always consult your plumber to make sure no interior pipes/drains are leaking. Usually, when your basement is leaking/seeping, it is caused by a drainage problem on the exterior of your home. Some older basements have thin walls and or cracks. Poor drainage outside can easily penetrate foundation walls and floors causing water damage and leaking/seepage.
Like the beluga, narwhals are medium-sized whales. For both sexes, excluding the male's tusk, the total body size can range from 3.95 to 5.5 m (13 to 18 ft); the males are slightly larger than the females. The average weight of an adult narwhal is 800 to 1,600 kg (1,760 to 3,530 lb). At around 11 to 13 years old, the males become sexually mature; females become sexually mature at about 5 to 8 years old. Narwhals do not have a dorsal fin, and their neck vertebrae are jointed like those of other mammals, not fused as in dolphins and most whales.
Newborn narwhal calves are about 1.6 metres long. Calves are weaned after a year or more; females reach sexual maturity at about six years and males at eight. They feed on fish, squid, and shrimp. Predators of the narwhal include killer whales and, to a lesser extent, polar bears and walruses.
