How Deep Should Pilings Be

Satisfy criteria for embedment depth, or how deep the piles must go. Engineers usually require at least 20 to 25 feet of embedment to get the bearing and security you need.

How deep should piles be driven?

That depends on the type of soil you have. Soils can vary, and piles should be installed to the load bearing strata of the soil. In some parts of the country, like New Orleans, this can be up to 100 feet. However in other parts of the country, such as Texas, it can be 7-10 feet.

How deep are bridge pilings?

A typical bridge column drops down about 80 feet underground – about the height of an eight-story building. Each pier includes a cylinder of rebar steel about 6-8 feet in diameter, woven into a lattice that creates hundreds of squares no more than 1 foot across.
