Cementitious Coating 851
(DWI 25(1)(a), BBA, WRAS) - cementitious modified polymer coating with high adhesion to both
steel and concrete
Flexcrete's
Cementitious Coating 851 is a two component, thixotropic,
cementitious modified polymer coating with high adhesion to both
steel and concrete. Cementitious Coating 851 forms a hard,
highly alkaline coating with a degree of elasticity which not
only protects the concrete, or other substrates, from the
effects of aggressive acid gases, moisture and chlorides, but
also has greatly enhanced chemical resistance.
Cementitious
Coating 851 is used for structural waterproofing of concrete
and other mineral substrates, resisting positive and negative
pressure under a 100 metre head. Designed for internal and
external sealing of water retaining structures, including
drinking water reservoirs. Waterproofing of road, ramp and
bridge decks prior to the installation of traditional asphalt
road surfacing.
Cementitious Coating
851 is extensively used for the protection of reinforced
concrete from chloride attack on highway and coastal structures
even in areas subject to immersion. Ideal for substructure
protection in chloride-laden ground conditions. Provides
reinstatement of effective cover for precast and insitu
reinforced concrete, enhancing durability to achieve specified
design life.
Advantages of
Cementitious Coating 851
Simple: Materials are
pre-packaged in a convenient and easy to handle size. Requires
only mixing on site.
Easy to use: Brush, trowel
or spray applied, normally in two coats.
Resistant: Good abrasion and
very high resistance to freeze/thaw cycles and de-icing salts.
Adhesive: Excellent adhesion
to steel and sound prepared concrete substrates.
Safe: Non-toxic when cured
and is listed as authorised under Regulations 31 for use in the
supply of water for drinking.
Impermeable: Dense matrix
offers low permeability to water, even at 10 bar pressure, and
very high diffusion resistance to carbon dioxide gas and
chlorides.
Compliant: Cements used are
quality assured complying with BS 12. Approved by the BBA,
Certificate No. 05/4276.
Cost Effective: Economical.
Overcoating: Easily
overcoated with other specialist membranes in the Flexcrete
range to provide further protection and aesthetic quality.
