Plymouth Foam has developed a 3 in 1 insulation board that can reduce issues caused by insulating foundations - SAV+R Foundation Protection™. This new product has been designed to not only insulate but also drain moisture better and reduce lateral pressure by unto 40%.
There are 3 advancements with RID Technology are important in todays construction to not only preform better but also reduce liability. R-I-D Reduced-Insulate-Drain
Reduce - Reduce lateral pressures by up to 40% using SAV+R Foundation. When lateral pressure pushes on the SAV+R foundation board, the integrated Stress Reducers™ can “absorb” this pressure and help save your foundation from failure. SAV+R has been designed to handle backfilling pressures, compacting pressures, clay or soil swell pressures and long-term lateral pressures.
Insulate - SAV+R uses Engineered EPS which provides a stable R-value for the life of the foundation. SAV+R is available with R-values of 5, 10 or 15. SAV+R Engineered EPS does not leach harmful chemicals into soil, has very low moisture absorption, is not affected by the freeze-thaw cycle, contains no ozone depleting chemicals and is 100% recyclable.
Drain - Water leaking into foundation walls via hydrostatic pressure can cause serious issues. SAV+R incorporates Easy Flow Drainage Pathways™ (EFDP) to move water quickly to the foundation drains. EFDP can help reduce insulation moisture absorption, reduce hydrostatic pressure, reduce frost heave, accelerate drying and can add longevity to the waterproofing.

Frequently asked questions. As an industry leader, we feel it is important to share our expertise as well as continue to educate and inform others of Plymouth Foam’s materials and capabilities.
Compressive strength is a crucial component for insulation and building materials. One of the most important mechanical property of Plymouth Foam's EPS is the resistance to compressive stresses, which increase as the density becomes higher. The compressive resistance is between 10 – 60 psi for most construction applications. Our Plymouth Foam product can be produced to meet your specific strength requirements per project needs.
