Piles or hemorrhoids is a painful condition of inflammation and swelling that affects the veins around the anus or rectum. Although the pain can often be unbearable, in most cases the condition itself is not threatening.
Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering disciplines and firms. Deep foundations can be made out of timber, steel, reinforced concrete or prestressed concrete.
