Underseal® Underslab Membrane

U.S. Patent No. 7,488,523
U.S. Patent No. 7,686,903

Underseal® Underslab Membrane is a tough, 85 mil pre-concrete pour waterproofing membrane/vapor barrier designed to virtually eliminate water and vapor transmission through concrete slabs on grade. In addition to protecting floor finishes and indoor air quality, Underseal® Underslab Membrane also acts as a barrier to methane and radon gas.

Underseal® Underslab Membrane provides a continuous seal underneath the foundation slab. A strong mechanical bond is developed between the membrane and concrete at time of pouring as the concrete intermingles with the fibers of the nonwoven geotextile. Underseal® Underslab Membrane is typically installed horizontally over a prepared sub base such as compacted soil, mud slab or #57 stone. 85 mil Underseal® Underslab can also be used in vertical applications.
