In the traditional joint waterstop structure of CFRD, a central bulb waterstop is
buried in joint concrete to serve as the middle dense line. Due to the poor
compactness of the concrete surrounding the waterstop and the deficiency of
deformation ability of the central bulb, this kind of waterstop has been proven
to be improper to perform its role of waterstop in joint.
In GB waterstop structure, the corrugated rubber waterstop is fixed by bolt on
the joint concrete surface to substitute the central bulb waterstop. The size of
the corrugated part is specially designed to absorb the joint deformation.
In China, corrugated waterstop has been widely used in CFRD joint,
especially those higher than 100 meters. Recently, it is also accepted by the
designer of Bakun CFRD of Malaysia.
Corrugated rubber waterstop is normally fixed by bolts on the top of
perimetric joint of CFRD, underneath the GB filler.
l Reliable connection to joint concrete (Compared with the traditional
buried central bulb waterstop).
l Designed deformation ability to absorb joint moves.
l Easy of installation and quality inspection.

GB-EPDM cover is a composite rubber plate composed of EPDM (Ethylene
Propylene Diene Monomer) plate and GB sealant layer. It can be used both as
a protective cover for the plastic filler, and as an independent defense line for
the top waterstop of CFRD.
As a waterstop composite material for waterstop, it presents a multiple
function. With the perfect resistance to ozone and heat ageing, EPDM layer is
a protective layer at the external surface; undersurface, GB sealant is applied
to solve the poor adhesion of EPDM layer with GB and concrete.
l Protective cover to the plastic filler for top waterstop of perimetric joint,
tension joint or compression joint of CFRD.
l Accustomed application under adverse conditions: sunlight, intense heat,
heavy humidity or chilly environment.
l Improve the flow ability of the plastic filler on the joint of CFRD.
l Resistant to ozone and heat ageing.
l Proper tensile strength and flexibility.
l Perfect adhesion to the plastic filler and concrete.
l Good adaptability to sunlight, intense heat, heavy humidity or chilly
environment.l Easy to installation.

Intersections
T shaped cover connecter Turning cover connecter
l Special intersections are very important in the waterstop system of
CFRD. The quality of intersections which connected perimeter joint
and vertical joint or different size waterstop will affect the waterstop
result directly.
l In view of this, many types of intersections have been developed tomeet the requirement. After tentative application, these intersections
are proven to be feasible practically.
