Most foundations are built to last 100+ years. However, several factors may affect this timeline. These include:
● Material used (wood may not last as long)
● Type of foundation (pier and beam may have a shorter life span)
● Quality of construction
● Type of soil and other natural elements
● How much water surrounds the foundation
● Whether the foundation is reinforced
As a homeowner, some of the most important actions you can take to protect your foundation are to keep an eye on it, solve any issues immediately and keep water away from it.
As a home builder, the most important thing is to be proactive. Consult a structural engineer and choose the best foundation for the area’s soil, waterproof the foundation while it’s being built and choose a professional who will do quality work.
