Do you think this might work as a base to support brick sidewalk pavers similar to the Brock Paver Base Panels?


You will want to consult with a design professional to determine the type of live and dead loads that your sidewalk will bear and the necessary compressive strength to support such weight. Typically, Dow recommends using a minimum of a 25 psi board for structural applications, such as under pavers. Because STYROFOAM(TM) is highly moisture-resistant and unlikely to absorb sitting water, you will additionally need to make sure that the design of your sidewalk allows for moisture to drain or escape in order to prevent challenges with seasonal expansion and contraction or any other issues that can be caused by sitting water. More information on calculating the load can be found below: https://dow-styrofoam.custhelp.com/app/answers/detail/a_id/3320/kw/structural/session/L3RpbWUvMTUwNDcyNTU4Ni9zaWQvZlVNcXJVM3puTGRwSjk1YkZhJTdFSGg2TW9SN3Zfek9jS1NNazY2cE54bm5xZzNjJTdFa21DcHRaNU9nVlZLWTFmRVpiY1JtaGZtVG4zciU3RURkN2p3VldTdG5tSFphd2cxdzRJUk1yNyU3RU03OUprR3VGNzdtM0pZSTJ1dVElMjElMjE%3D If you have any further questions on your project, please call Dow at 1-866-583-2583 and select prompt 8 to speak with a representative.
