VaporBlock®20 Plus- The Gas Blocker
VaporBlock 20 Plus plastic sheeting is intended for under-slab applications where soil-borne gases like radon are a concern. It is 50 times less permeable than typical high-performance polyethylene vapor retarders. This is due to it's tight cell structure. This gas blocker is much less expensive than comparable products. A 10-foot-by-150-foot roll costs about $525. For radon blocking, seams should be sealed with a special foil-backed tape (VBP4VB Plus Tape) that costs $32 per 4-inch-by-210-foot roll.
