thermoplastic elastomer rubber
0.2” x 0.78” (5mm x 20mm)
Waterstop-Strip is a strip applied hydrophilic rubber swelling waterstop for
use in all kinds of cast-in-place concrete construction joints, as well as steel,
concrete and thick-walled PVC (min. 1⁄8” (3.1mm)) pipe penetrations. When
exposed to water, the rubber expands, creating a compression seal within
the joint or pipe penetration, blocking the passage of water.
Start of swelling (water contact)
approx. 6 hours
approx. 50% after 2 hours
approx. 460% after 24 hours
approx. 850% after 8 days
• Vertical and horizontal cast-in-place concrete joints where limited
movement is expected.
• Around through-wall pipe penetrations.
• Ideal for new concrete structures or between new and existing concrete.
14°F (-10°C) – 113°F (45°C).

• Easy to use
• Rapid expansion
• Dimensionally stable, even at high temperatures
• Reproducible swell after wet/dry cycling
• Suitable for fresh and salt water
• Contains no bentonite
• Concrete surfaces and/or pipe must be clean and free from laitance,
dirt, dust and any other bond inhibiting substances.
• It is essential that there is at least 3” coverage of concrete from the side
exposed to water.
• Bond Waterstop-Strip with a suitable adhesive, such as Bostic ISR 940A,
3M 740 Hybrid, SoudaSeal FC or equal.
• Apply a bead of adhesive and press the Waterstop-Strip into the
adhesive until it oozes out from beneath. A 3⁄16” x ¼” (~4.5 - 6mm) bead
will yield approximately 30 lineal ft (9 m) of coverage. Do not begin
the placement of concrete for at least 8 hours after bonding. Ensure that
the waterstop makes complete contact with the substrate. Waterstop
connections can be made by overlapping by 2” (50 mm) or by butt
jointing. The waterstops must be placed tightly together to prevent
gaps. Butt jointed waterstops must be covered by a separate section of
waterstop with a 1¼” (31.75 mm) overlap to both sections.
• Alternately, Waterstop-Strip can be fastened with masonry nails, 1½ –
2” (40 – 50mm) long with a ¾” (20 mm) diameter washer. Space nails
at a maximum of 8” (200 mm) centers with a minimum spacing to ensure
proper substrate contact.

• Store the waterstop dry.
• Protect the waterstop from moisture until the concrete is poured.
• Before concrete placement, visually inspect the waterstop.
Swollen waterstop is unsuitable and must be removed.
• Do not use around PE pipe.
2 years, stored dry, frost free, in the original unopened packaging.
