Traditionally, the foundations of houses were made of concrete  A builder is experimenting with using a hard plastic polymer for foundations  A foundation made with the polymer is about the same price to construct and install as is concrete foundation  Unlike concrete, the polymer will block all water flow and is not prone to cracking with age

 The builder argues that houses built with the polymer foundation will last longer
