120
Integrally bonded vapor protection for
slabs on grade
Grace Waterproong Products
Product Advantages
• Forms a powerful integral seal
• Protects valuable oor nishes
• Ultra low vapor permeability
• Durable, chemical resistant
• Lightweight and easy to apply
The membrane is loose laid onto the prepared sub-base, 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 accor-
dance with ASTM E1643-98.
Description
Florprufe
®
120 is a high perfor-mance vapor barrier with Grace’s
Advanced Bond Technology
TM
that forms a unique seal to the
underside of concrete oor slabs.
Comprising a highly durable polyolen 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
• Forms a powerful integral seal to the underside of concrete
slabs
• Protects valuable oor nishes such as wood, tiles, carpet and
resilient ooring 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 polyolen sheet
• Lightweight, easy to apply, kick out rolls
• Simple lap forming with mechanical xings
or tape
Use
Florprufe 120 is engineered for use below slabs on grade with
moisture-impermeable or moisture-sensitive oor nishes 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.
