C603.2.2 Membrane Soil-Gas Retarder

2020 FBC - Building, 7th edition > C Florida Standard for Mitigation of Radon in Existing Buildings > C6 Soil Depressurization Systems > C603 Soil Depressurization System Design Criteria > C603.2 Submembrane Depressurization Systems > C603.2.2 Membrane Soil-Gas Retarder
JUMP TO FULL CODE CHAPTER
A membrane soil-gas retarder shall consist of a 8 mil or thicker single ply polyethylene sheet or other sheeting material of equal or lower permeability and equal or greater strength. Place sheeting to minimize seams and to cover all of the soil below the building floor. Retarders must provide excellent environmental stress crack resistance, impact strength and high tensile strength including additives to retard polymer oxidation and UV degradation. Where pipes, columns or other objects penetrate the soil-gas retarder, it shall be cut and sealed to the pipe, column or penetration. All seams of the membrane shall be lapped at least 12 inches (305 mm). Punctures or tears in the membrane shall be repaired with the same or compatible material.
