Rubber Water Stop Belt
Rubber water stop is used in the large concrete structure,
for example, dam, cistern, basement, etc. Pouring rubber
water stop in deformation joint and working place is to
prevent leaking.
What is rubber water stop?
A rubber water stop is an integral sealing system used on
all types of concrete structures to keep liquids in and
out. The rubber waterstop is made of natural rubber or
synthetic rubber, adding various additives and fillers, and
then plasticizing, mixing, pressing and molding.
Rubber Waterstop Type
Divided by water stops shape
Dumbbell type: suitable for construction joints, shrinkage
joints and joints where shearing motion is not possible.
Center bulb type: suitable for expansion joints and joints
with a large amount of movement.
Divided by water stops material
Natural rubber waterstop, neoprene waterstop,
styrene-butadiene rubber waterstop.
The rubber waterstop is a new type of shock absorption,
seismic design and reinforcement method. Its main function
is to reduce the relative displacement of the beam pier and
prevent the beam body from falling off the support. If you

Rubber Water-stop Application
Rubber water-stops are usually used in construction joints,
settlement joints, deformation joints and movable joints to
prevent leakage, absorb shock and ensure project life.
Rubber waterstop strip is suitable for portable tanks,
water and sewage treatment facilities, foundations,
basements, subways, dams, reservoirs, canals, cisterns,
aqueducts, tunnels, subways, culverts, parking lots, bridge
decks, abutments, elevator pits, roofs, Floor slabs,
swimming pools, embankments, retaining walls, underground
facilities, stadiums, storm drains, etc.
