SperrJOINT®
bentonite Waterstop
new patented Bentonite Waterstop.
NO premature hydration and expansion caused by
… rain water, - ground water, - and bleed water
during application of SperrJOINT® and second concrete pour.
Description
evolution in BENTONITE WATERSTOP…
SperrJOINT® ...100% pure Bentonite
coupled with a retarded hydration initiation.
Specially formulated “skin” retards
initialization of the hydration process of
the Granular 100% Natural Sodium Bentonite

SperrJOINT® tecnology
SperrJOINT®
overcomes
the problem of instantaneous and uncontrollable
hydration experienced with Granular Sodium
Bentonite WATERSTOP when it comes in contact
with water during the normal construction process.

About Bentonite Waterstop
The Sodium Bentonite is Hydrophilic clay volcanic origin
The BENTONITE WATERSTOP must be kept dry prior to use;
exposure to water (rain water, ground water and
bleed water) prior to contact with fresh concrete will
initiate premature hydration and
expansion.
This produce a low colloidal consistency (SOL state),
which
renders the Bentonite Waterstop unsuitable for effective
waterproofing.
If the hydration process of Bentonite Waterstop commences
after the placement of the second pour of concrete, Bentonite
becomes a colloidal GEL that is a very effective,
leak proof waterproofing barrier.
This GEL state is produced with the MINIMUM expansive capacity within its
capability and at the same time it produces the MAXIMUM expansive force
that will be realized during the lifetime of the structure.

HOW
DOES IT WORK
The Granular Sodium Bentonite which is the heart
of the SperrJOINT® is packaged in specially
formulated film which delays the start of the
hydration process for a period of time that is
approximate to the installation period and the cure
time of the concrete.
This delay means the Bentonite will not react to
rain, ground water or bleed water during the
placement of the material and the placement of
the second concrete pour.
The hydration and accompanying expansion of the
Bentonite used in this
patented system, is effectively delayed until after the concrete from both
pours has developed sufficient strength to withstand internal pressures.
DESCRIPTION OF
SperrJOINT®
system
1) - SperrJOINT®
- Specially designed plastic “ skin” that delays the hydration and
expansion process’s.
- The “skin” is packed with 100% Natural Sodium Bentonite.
2) - Anchoring device
- cover : Glass fiber strip sized for each
Sperrjoint®
section - supplied.
- blockjoint : metal clips
- supplied.
- nails : nails for powder actuated tools - supplied.

SperrJOINT®
ADVANTAGES
Guarantees
a positive waterproofing capability to
building and other types
of structural foundations.
“Tim Delay
Skin” prevents premature hydration and expansion caused by
rain water, ground water and bleed water
during application of SperrJOINT® and
second concrete pour.
NOT
SUBIECT to premature, accidental
hydration and expansion as often
experienced in
other systems.
The
hydration and expansion process’s
commence after the concrete sections
have been cast thereby eliminating
potential damage to the structure.
Hydration
and expansion of the
SperrJOINT® do not take place until after the concrete has realized it’s
initial cure and is capable of with standing the internal pressure.
Therefore potential damage to the structure is avoided.
SperrJOINT®
technology avoids the premature hydration and expansion of
the Bentonite avoiding the muddying of the concrete, which creates
bonding problems.
SperrJOINT®
leak proof water barrier is easily placed and provides a
positive waterstop, thereby assuring lower construction costs with no
costly replacements or
repairs.
SperrJOINT®
WATERSTOP TECHNOLOGY, the ability to retard hydration
and expansion, are designed to overcome the disadvantages and
drawbacks common with earlier waterstop design.
