Poured concrete block bases and slab foundations will last for a lifetime, 80 to 100 years or more, given they have been constructed with precision. The termite proofing of the base, 12 years, provided the chemical barriers remain intact. Properly installed waterproofing with bituminous coating should last 10 years.
How Long Does Concrete Foundation Last?
Concrete foundations can last for a long time, even centuries, depending on the type of foundation, the quality of the materials used and how well it is maintained. There are many factors that can affect the longevity of a concrete foundation, including ground movement, water drainage, and weathering.
In general, a well-constructed concrete foundation should last at least 50 years. With proper maintenance, a concrete foundation can last much longer. The most important factor to consider when determining the life span of a concrete foundation is the quality of materials used. A foundation built with high-quality materials, such as reinforced concrete, will last much longer than one built with lower-quality materials.
Ground movement is also a factor that can affect the life of a concrete foundation. If the foundation is not built on solid ground, it can be susceptible to cracking and shifting. Regular inspections should be done to ensure that the foundation is stable and is not affected by ground movement.
Water drainage is another important factor to consider when determining the life span of a concrete foundation. Poor drainage can cause water to pool around the foundation, which can cause cracks and other damage. To avoid this, make sure that the area around the foundation is properly graded and that any water that collects is
