What is a Pier?
A pier is a vertical support structure, often made of concrete, steel, or wood, that is installed deep into the ground to provide stable support for a building. It is used when surface soil is too weak to bear the load of the structure.
What is a Grade Beam?
A grade beam is a horizontal beam that sits on top of piers or piles, connecting them to create a stable foundation. It helps distribute the building's load evenly across the piers, providing support and preventing settling. Grade beams are commonly used in pier and grade beam foundations to support structures in areas with poor or shifting soil.
Pier and Grade Beam Foundation
A pier and grade beam foundation consists of vertical piers (typically concrete or steel) that are drilled deep into the ground to reach stable soil, connected at the surface by horizontal grade beams. This system evenly distributes the building's load. It's particularly suitable for areas with poor or expansive soil, high moisture levels, or regions prone to soil movement, such as floodplains or areas with high water tables. It’s also ideal for sloped sites or locations where traditional slab foundations are not feasible.
