Get your rocks off
July 1st 2011 The CoGri Group has
acquired European
distribution rights for the
patented SD7 Joint Saver,
which will be marketed as
the CoGri Joint Stabiliser
and managed by CG
Flooring Systems.
The CoGri Joint
Stabiliser (CJS) is a fast,
cost-effective method for
eliminating rocking slabs.
It is a split aluminium cylinder
containing a screw and wedge torque
mechanism.When inserted between
two slabs and expanded, the pressure
provides the interlock needed to
restore load transfer and virtually
eliminates harmful slab movement.
The spring-like mechanism
allows it to expand and
contract with the slab as it
undergoes normal slab
movement due to temperature
changes. CJS comes
in different sizes – 200, 175
and 150mm – depending on
the slab depths. The
company says that,
compared to other methods
of correcting rocking slabs,
CJS is less disruptive and requires less
warehouse downtime. More articles from CG Flooring Systems Ltd: |
