                     the bentonite waterstop with a plastic film

                                         that remains intact until

                                            to the second concrete pour

                                            and until to cured concrete

its plastic film  remains intact to "PROTECT"

the bentonite until to the concrete is cured

SperrJOINT^®  plastic film,  even if in contact with  sun, wind, rain,

.... is insensitive to rain water  ...

... during the installation period ...until the placement time of the second concrete pour

 butil rubber
            +bentonite

preGEL bentonite waterstop

thus the waterstop becomes a  

" NO  waterstop "

The plastic film of SperrJOINT^®
avoiding the premature hydration

and expansion of the Bentonite ,

avoids the SOL phase which

causes the muddying of the concrete

reinforcement causing bonding problems, with reduction or zero setting of the iron/concrete matrix..

    it zero sets

    some building site risk :
1 -premature hydration
2 -reduction or zero setting

    iron/concrete matrix
    exatly in the zone,

    where  the iron/concrete
    matrix must be maximum.

This phenomenon is caused by mudding of the concrete reinforcement because the concrete push forward the expanded Bentonite during the
casting.

.....if the concrete surface where 

     waterstop will be place, is flooded,
SperrJOINT^® always works as the most effective waterproofing system, available for cold joint and with no costly replacements

or repairs.

                          when the film dissolves
      ... 2- connect   the expansion of the Bentonite

 it means don't have knowledge of a new art in

                bentonite leakproofing technology.
Identify the effective waterproofing barrier

      with the Bentonite's expansion  that we can see,  
      no knowledge of leakproofing engineering,  

      no knowledge how the Bentonite works

          in the bentonite waterproofing

 note:

  "extruded " type

           waterstop

 it is not enough to place a waterstop with "low art"
   and hope the waterstop will work succesfully.   
     If waterstop is not firmly fixed to the   concrete surface

      where it was installed, the concrete grout,

        goes  under the waterstop.
         It is surrounded by concrete, thereby waterstop            becomes similar  as an reinforcement bar

   The installation and application recommendations     

     of a  waterstop are definite.
       The most important Producer's   warnings and

         recommendations in order to install the bentonite

          extruded  waterstop are :       
            the extruded  bentonite waterstop
             (e.g.  bentonite/butyl rubber based waterstop)
               must be  GLUED to the concrete.

SperrJOINT®

evolution : >    from "abc-extruded" bentonite waterstop   to   SperrJOINT^®

Said film allows the most
effective

leak proofing barrier                   

against water that is realized
after the casting and the
curing of the concrete.

....will have no cracks,       

chippings, caused by

premature

expansion's force

of the Bentonite,

during the time required

for the concrete curing.

With a new technology, with an article insensitive to rain water,
ground water and bleed water

during the time required betwen

initial installation of waterstop
SperrJOINT^® and the horizontal and
vertical second  casting,
  SperrJOINT^® has overcome the

limitations and the disadvantages

of the background art like the
premature hydration and expansion

of the Bentonite.
SperrJOINT^® works when the

concrete has been casted and it has

developed sufficient strength to

withstand internal pressures.
SperrJOINT^® avoids the problem    

to work quickly   
(reinforcing and forming)  
to avoid the risk of premature

expansion of the bentonite waterstop.

SperrJOINT^® waterstop technology

pays attention to engineering

2-  It does not make

     holes in the

     concrete causaed

     by SOL Bentonite

     made by

     premature
     hydration and
     expansion of
     Bentonite.

SperrJOINT^® has a specially plastic film that is made to coat the Bentonite and said

plastic film is able to delay  the hydration and expansion process
until and after  that the concrete will be casted and it has developed sufficient strengt to withstand internal pressures.
