Welcome to the OPTI-SDS Project

Welcome to the Website of the OPTI-SDS project "An investigation of the OPTImum specification for Soil Depressurisation Systems (active and passive) that take account of Irish Building Practices".

The OPTI-SDS project is funded by the Irish Environmental Protection Agency and is expected to be completed by July 2019.

Project objectives

 This project aims to conduct an investigation of the optimum specification for soil depressurisation systems (active and passive) that take account of Irish Building Practices. The National Radon Control Strategy for Ireland has identified several knowledge gaps, including the optimum specifications for passive soil depressurisation systems that take account of Irish building practices. The impact of modern hardcore and stack systems on the effectiveness of the radon sump will be investigated under controlled laboratory conditions.
