Sika-101h

USES
Sika-101h forms slurry consistency when mixed with
water. When it is applied to
the concrete substrate it forms insoluble crystals inside water bearing capillaries
and seal against further seepage of water. Sika®-101h
blocks the pores in concrete
structures such as :
▪ Basement
▪ Reservoirs
▪ Sewage water and effluent treatment plant
▪ Tunnel and underground subways
▪ Foundations
▪ Swimming pools
▪ Underground parking structures
▪ Water tanks

CHARACTERISTICS / ADVANTAGES
It provides the following beneficial properties in post
applied waterproofing :
▪ Easy to apply
Can be used for positive and negative side waterproofing
▪
▪ Helps in faster construction schedule
▪ Can seal hairline cracks
Becomes an integral and homogenous part of the
stucture
▪
▪ Allows the substrate to breath
▪ No added chloride
▪ Non-toxic

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Concrete surface must be clean, sound, level and uncontaminated by oil or grease.
Remove cement laitance, formwork-traces and loosely
adhering particles by
mechanical means. Area of honeycomb concrete and
other surface imperfections
must be repaired with cement sand mortar. De bonding render must be removed.
Wet surface until saturated.

MIXING

Add powder to given amount of water and stir with
low speed mixer for 5 minutes
until a lump free smooth brushable consistency is
achieved.
APPLICATION
During application of Sika-101h add a liquid applied
polymer modified flexible
coating system with crystallisation properties. The following procedure shall be
adapted for application.
For the 1st Coat of Sika®-101h is mixed with water to
produce crystalline slurry and
to be coated with the help of a brush or roller.
When the first coat is in tacky condition Sika-101h is
mixed with water to produce
crystalline slurry and to be coated with the help of a
brush or roller.
Sika®-101h also has multiple application as
Dry shake over freshly laid PCC ( no waiting time required after PCC for waterproofing)
