Multiguard IWP /2015/R0-2015
DO YOU KNOW?
PRODUCT DESCRIPTION:
Concrete is an inexpensive, readily available, versatile, strong material
available for more than 100 years. But, it is also a hard sponge; hydrophilic and
soaks up water. A waterproofing system is needed to stop water from getting in,
and from damaging rebar in the concrete. An integral waterproofing system is
the most economical, effective and an environmentally-friendly alternative to
membrane waterproofing.
PRODUCT DESCRIPTION:
Multiguard®
IWP is an advanced integral waterproofing product based on specially
processed polymers and active ingredients with permanent waterproofing
characteristics. Based on nanotechnology, Multiguard®
IWP creates millions of
particles filling all pores and cavities available in the concrete and plaster, thus
waterproofing structures permanently.
Ordinary concrete absorbs water and dissolved salts through its network of pores,
leading to water infiltration and corrosion of steel reinforcement. Multiguard®
IWP
reduces absorption to 1% or lower and forms a protective coating around steel
reinforcement. Less water and fewer chlorides are able to penetrate the concrete and
the reinforcement has enhanced protection from corrosion.
Using Multiguard®
IWP allows real estate owners and builders and developers to have
the comfort of knowing their investment/project remains protected against one of
nature’s most damaging elements e.g. water.
Multiguard®
IWP works by improving dispersion of the agglomerates with the concrete
mix, which ensures that the cement is used more efficiently.
USES:
Multiguard®
IWP reduces permeability throughout the depth of concrete, improves
workability, with greater protection to rebar due to special corrosion inhibitors. This
also makes concrete/mortar easier placing hence better compaction and finishing.
Because of water retaining properties, Multiguard®
IWP helps in reduction in drying
shrinkage cracks and hardened shrinkage cracks. It also has Internal concrete/plaster
curing properties. Lower cement content for specified strength and workability. It
increases strength and durability with higher cohesion. It reduces risk of segregation

USAGE GUIDELINES:
Use other superplasticizers as per the manufacturer’s recommended rate and
requirement for the placement of green concrete in the project.
Cementitious Content: The cementitious content of concrete containing Multiguard®
IWP will not be less than 300 kg/m3 with up to 15% fly ash or 30% slag replacement.
Water-Cement Ratio: 0.42 maximum. Water content of Multiguard®
IWP and other
admixtures to be included in the water to cementitious ratio.
