Sub Slab Depressurization (SSD) System

IAT designs and commissions sub slab depressurization (SSD) systems. These systems reduce and eliminate soil gas (e.g. radon) and rising damp entry to the basement. This is done by depressurising and ventilating below the basement floor slab. Cost are less expensive than full ECHO Basement Systems which depressurise, ventilate and protect interior basement finishing construction against moisture problems while removing soil gas.

SSD is used in buildings and homes with soil gas and dampness problems, where the basement is not being finished or refinished. An SSD system can be installed and operating within a day, and reductions in soil gas levels achieved within a few hours of operation. Soil gas reductions can be dramatic. For example. in a recent installation, the radon level in the basement was reduced from over 15 pCi/L to 1 - 1.5 pCi/L.
