The service life.
How much the strip foundation will last depend on what material it is made of. The brick foundation is designed for 30-50 years of operation, a prefabricated concrete foundation will serve for 50-75 years, monolithic concrete or lactine, on a cement mortar, the tape is operated up to 150 years.
