EPS has been used successfully for many years in areas where moisture is a concern, specifically below grade. Fungi, bacteria and rot do not affect EPS. The performance properties will not deteriorate when exposed to moisture and/or water. EPS will breath, allowing the diffusion of moisture. EPS insulation is available in a variety of densities to suit project needs. ASTM C578 provides performance properties on expanded polystyrene foam insulation.
