Polyurethane liquid membrane cementitious waterproofing method.
Waterproofing membrane for concrete slab.
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.
The traditional plastic barrier used for under slab protection is a moisture barrier and is not a waterproof membrane.
For example on a flat terrace a waterproofing membrane could be laid above the structural slab and below the finish tiles.
In addition to protecting floor finishes and indoor air quality underseal underslab membrane also acts as a barrier to methane and radon gas.
This layer is continuous and does not allow water to pass through it.
It is ideal for repair maintenance or new construction applications.
