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.
