Types of House Foundation
A house foundation is a structure that provides a base for a house. The house’s exterior walls and interior partitions are typically then built around this framework so they sit flush with the ground, protecting external elements such as water damage or insects. There are three main types of house foundations: slab-on-grade foundation, pier & beam foundation, and post & beam foundation.

Slab-on-Grade Foundation
A slab on grade foundation involves digging out an area in which to build your home’s lowest level (usually includes one basement), pouring cement onto the soil until it reaches the necessary height needed for building flooring; rebar is inserted into concrete during the construction process to provide support; once finished you have what is called a “footing”, which is the bottom of your house as it sits on top of the ground.

pier & beam foundation
A pier and beam foundation involves constructing a framework from wood or metal that extends to below grade; these beams are then strengthened by pouring concrete around them for added support; this type of house foundation can be excellent for areas with difficult terrain because they require minimal excavation.

Post&Beam Foundation
A post&beam house foundation uses vertical posts, horizontal beams spanning between them at intervals to provide structural stability (reinforced with poured concrete); may result in an open-air living space under a high ceiling due to the use of large pillars or trusses.
