FOUNDATIONS STEPS TO CONSTRUCTING A MOISTURE-RESISTANT FOUNDATION Build a Better Home Details are critical when constructing a sound building foundation that will withstand water and control dampness. VDOT states 75 years for higher functional classification roads and 50 years for lower functional classification roads. Fine particles are more sensitive to the presence of water than coarse particles. The behavior of a material where the material deforms under load and does not go back to its original shape is called plasticity.
