The Benchmark for Expandable Waterstops
Sika® Hydrotite IS A STATE-OF-THE-ART HYDROPHILIC WATERSTOP with unmatched durability and watersealing capacity. Comprised of NON-BENTONITE, modified chloroprene rubber, Sika® Hydrotite expands up to EIGHT (8) TIMES its original volume when exposed to water. This expansion creates an effective compression seal within joints of limited movement. Recognized worldwide, Sika® Hydrotite has a proven track record as a high quality and cost effective solution to your water containment needs.
EXCEPTIONAL QUALITIES TO ENSURE UNPARALLELED PERFORMANCE:
• Comprised of NON-BENTONITE, modified chloroprene rubber
• Outstanding physical properties
• Available as a co-extruded profile to provide directional expansion (also available as a single extrusion)
• Special expansion delay coating to allow concrete cure prior to expansion
• Reliable and durable (lifespan up to 100 years)
• CJ-0725-3K-ADH and CJ-1020-2K-ADH offered with an adhesive back
• Simple, low cost installation
• Available in a multitude of sizes and shapes for numerous applications
• Appropriate for retro-fit as well as new construction
• Can withstand high hydrostatic pressures (150’ head for most profiles)
• International acceptance
TYPICAL STRUCTURES UTILIZING Sika® Hydrotite:
• Water and waste water treatment facilities
• Primary structures
• Tunnels and culverts
• Dams, locks, canals, water reservoirs and aqueducts
• Pipe penetrations
• Swimming pools
• Storage tanks
• Retaining walls
• Slabs on grade
Sika® Hydrotite CJ
A SUPERIOR WATERSTOP FOR CONCRETE JOINT GAPS
As this innovative product absorbs water and expands, it conforms to gap variations along the joint. This action ensures complete sealing even under extraordinary hydrostatic pressure. Due to its slim profile, it won’t project like conventional waterstops and trap air or become displaced by the second pour. The result is optimum concrete placement. Sika® Hydrotite CJ, is treated with a special expansion-delay coating to prevent it from reacting to the fresh, moist concrete and expanding before curing takes place.
Sika® Hydrotite RSS
SEAL FOR SAWED CONTROL JOINTS/ JOINT REPAIRS
Sika® Hydrotite RSS profiles create effective seals in sawed control joints and in the repair of failed joints. Sika® Hydrotite eliminates hydrostatic pressure below the sealant, thus extending the sealant’s life. Select solid profiles with slightly larger diameters than the joint width for joints of consistent widths. Hollow profiles should be selected based on the maximum width of joints with varying widths. Compress both profiles slightly on initial insertion.
Sika® Hydrotite DSS
PIPE PENETRATIONS/PIPE THIMBLES
The DSS, DS, SS, RS, and CJ profiles can be bonded to various piping materials, including concrete, steel and plastic. Bond Sika® Hydrotite DSS to the pipe prior to concrete placement. Installation in existing walls requires an oversize cutout be made and Sika® Hydrotite installed both on the pipe and the outside diameter of the cutout. Fill the annulus with a nonshrink grout. Embedded pipe thimbles can also be sealed with Sika® Hydrotite DSS.
Typical EXPANSION pressures of Sika® Hydrotite are shown above.
SWELLING characteristics of Sika® Hydrotite depend on the water quality as typical examples show above.
Sika® Hydrotite rings are available in a range of internal diameters to meet varying needs. Sika® Hydrotite hydrophilic rings may be installed wherever a penetration through concrete needs to be sealed. Conduits, pipes, embedded sleeves, concrete wall ties, etc., can all be sealed utilizing Sika® Hydrotite rings.
