Drago Sealant

This two-part vapor barrier sealant helps remediation and concrete crews detail pipe and conduit penetrations quickly and reliably. It builds a durable, vapor-tight bond to membranes and substrates, preserving barrier continuity under slabs and on contaminated sites. Trowel around crowded penetrations and irregular profiles without slumping or voids. Bond to polyethylene/HDPE membranes, concrete, PVC, and metal for long-term adhesion. Maintain flexible, vapor-tight seals through thermal cycling and slab movement. Reduce rework with a predictable mix ratio and quick cure to stay on schedule. Cover medium to large installs efficiently with a professional two-part kit. Confirm compatibility with your vapor intrusion barrier system; primer may be required on dusty or damp concrete.
