APPLIED USE OF PVC & RUBBER �WATER-STOPS ON CONCRETE STRUCTURES

Examples of implemented sealing of Construction / Expansion Joints by PVC & Rubber Water-Stops

2. PVC Water-Stop
PVC waterstop, being embedded
in the concrete joints, acts as a
continuous watertight diaphragm
to prevent any seepage of liquids
in constructions joints which are
subject to hydrostatic pressure. It
is designed for expansion or
contraction joint; meanwhile, it
can accommodate lateral and
transverse movements which
make it capable to suit the
moving joints.
The PVC waterstop is extruded
form an elastomeric plastic
material including high grade
polyvinyl chloride, special resin
and some chemical additives such
as plasticizers and stabilizers. The
high material makes PVC
waterstops unsurpassed with a
variety of features and benefits as
shown follow.

17. Rubber Water-Stop
Rubber waterstop, made of
quality SBR (styrene butadiene
rubber), neoprene rubber or
natural rubber, is one of the
widest types for concrete
structure to prevent liquid
leaking in or out. Generally,
designed to be cast in the
concrete, rubber waterstops
are ideal for applications where
high physical properties of
rubber are required. For
example, reservoirs, dams and
other water retaining or
excluding applications with
high movements or water
pressure.
