HYDROSwellExpanding Waterstop for Concrete

GREENSTREAK

HYDROSwell is a specially formulated, high-performance, swellable, one-component, polyurethane-based waterstop for use in a variety of construction joints. Swelling rubber creates a compression seal within the joint, blocking the passage of water.

Applications: Construction joints in new water containment concrete structures Construction joints between new and existing concrete Pipe penetrations through walls and floor slabs Joints between precast elements Irregular joints or rough surfaces

Advantages: Swells up to 100% in potable water Permanently water resistant and does not dissolve in

water Elasticity withstands wet/dry cycling Very economical and easy to apply No nails, primer, or adhesive required Capable of sealing construction joints with head pressures of up to 50 psi (115 ft. head) Limited expansion eliminates cracking in fresh concrete Suitable for sealing rough surfaces and irregular pipe penetrations Saves labor by eliminating inverted keyways, split forming or heat splicing Single component, no mixing required Allows more thorough vibration of concrete at joint, resulting in better concrete

consolidation, which aids in achieving a watertight joint

Product Data: Temperature of Product for Best Application: 50 to 90F Storage Conditions For best results: store dry at 70F (20C) before usingTack Free Time at 73F, 50% Relative Humidity: 2-3 hours Shelf life: 9 months Color: red Shore a hardness: 10-30Swelling Capacity: 1 day 100% (slightly reduced/delayed swelling properties in salt water)

Suggested Cross Section of Extruded Bead:Concrete Thickness Number of Beads Side length of triangular bead 8-12 1 5/8 12-20 1 3/4 > 20 2 3/4Note: If the maximum size aggregate in the concrete is greater than 1 inch, use 3/4 inch triangular section(s).

PackagingDisposable 10 fl. oz. cartridges, 12 cartridges per carton

Surface Preparation Clean all surfaces. Substrate must be clean, sound, free of loose particles, dust, laitance, oils, and other contaminants. Surface may be dry or damp, with no presence of standing water. Do not leave the product in contact with wet concrete, or on a surface with a very high moisture content, for a long period of time, before casting new concrete. These conditions initiate swelling action and will decrease the adhesion between the HydroSwell bead and the surface of the joint.

Limitations Not suitable for expansion joints. Protect from rain to avoid expansion before placing new concrete and to assure 100% swelling capacity. Avoid placement of the concrete from a height greater than 20 inches. If this is not possible, allow HydroSwell

to cure for 2 days before placing concrete.

ApplicationRecommended application temperatures: 50-90F. Extrude material using a caulk gun. Attach the nozzle included in the carton to an opened cartridge and trim to desired size. The nozzle is scored to extrude one of three sizes with additional scores to produce a triangular bead. Apply a uniform, continuous bead to the hardened concrete or penetration. After applying HydroSwell, wait for approximately 2 hours before placing additional concrete. The minimum thickness of concrete around the HydroSwell should be 4 inches on each side (reinforced concrete) or 6 in. on each side (non-reinforced concrete) and 4 inches on top. For optimum application, store at 70F for a minimum of 8 hours prior to use.
