Product Discription
Comprising a highly durable polyolefin sheet and
a specially developed, non-tacky adhesive coating,
Florprufe 120 seals to liquid concrete to provide
integrally bonded vapor protection.
Florprufe exceeds ASTM E1745 Class A rating.
Advantages
Advantages
Forms a powerful integral seal to the underside
of concrete slabs
Protects valuable floor finishes such as wood,
tiles, carpet and resilient flooring from damage
by vapor transmission
Direct contact with the slab complies with the
latest industry recommendations
Remains sealed to the slab even in cases of
ground settlement
Ultra low vapor permeability
Durable, chemical resistant polyolefin sheet
Lightweight, easy to apply, kick out rolls
Simple lap forming with mechanical fixings
or tape
Use
Florprufe 120 is engineered for use below slabs on
grade with moisture-impermeable or moisturesensitive
floor finishes that require the highest
level of vapor protection.
Florprufe complies with the latest recommendations
of ACI Committees 302 and 360, i.e. for
slabs with vapor sensitive coverings, the location
of the vapor barrier should always be in direct
contact with the slab1.
The membrane is loose laid onto the prepared subbase,
forming overlaps that can be either
mechanically secured or taped. The unique bond
of Florprufe to concrete provides continuity of
vapor protection at laps. Alternatively, if a taped
system is preferred, self-adhered Preprufe Tape
can be used to overband the laps.
Slab reinforcement and concrete can be placed
immediately. Once the concrete is poured, an integral
bond develops between the concrete and
membrane.
Installation
Health & Safety
Refer to relevant Material Safety Data Sheet.
Complete rolls should be handled by 2 persons.
Florprufe 120 can be applied at temperatures of
25ºF (-4ºC) or above. Membrane installation is
unaffected by wet weather. Installation and detailing
of Florprufe 120 are generally in accordance
with ASTM E1643-98.
