`
`PRODUCT DESCRIPTION
`Swellseal® WA
`is a single component
`hydrophilic mastic, designed
`for sealing
`smooth to very irregular construction joints
`and pipe penetrations. Swellseal® WA is
`supplied in cartridge or sausage. Material
`cures and swells in the presence of moisture
`or water. Curing Time
`is dependent on
`temperature and humidity, i.e. curing time will
`decrease if temperature and RH are higher.
`Swellseal® WA will become firm in 24-36
`hours. Performance is not affected by the
`curing time.
`
`APPROPRIATE APPLICATIONS
`• Sealing of rough and smooth
`construction joints of cast in-place or
`precast concrete in wet and underwater
`applications.
`• Sealing joints between pre-cast
`segments in wet or underwater
`applications (e.g. manholes, box
`culverts, cable ducts and pipes)
`• Sealing of the joints between sheet
`piles.
`
`•
`
`
`• Swellseal® WA adheres to concrete,
`PVC, HDPE, steel, and fibreglass
`In contact with water Swellseal® WA
`will expand to more than 200% of its
`original cured volume.
`• Flexible system, which adapts to the
`irregular surfaces
`• Easy application with standard
`caulking guns
`• Durable cured material will exceed the
`life of the structure.
`• Good chemical resistance (*).
`• Resistant to petroleum products,
`greases, mineral and vegetable
`oils
`(*) For Chemical resistance contact the Technical
`Service Department @ 800-732-0166
`
`
`ADVANTAGES
`• Solvent free
`• Due to its special formulation,
`Swellseal® WA can
`be applied to wet surfaces or in
`underwater applications.

`
`LIMITATIONS
`the
`Applied at
`temperatures below 40ºF
`material will take approx. 10 to 15 days to cure
`(material cures slower at cooler temperatures
`and conversely working and cure times will be
`substantially reduced at higher temperatures).
`
`SURFACE PREPARATION
`Refer to DeNeef Surface Preparation
`Guidelines for more details.
`
`INSTALLATION PROCEDURES
`Swellseal® WA should be applied onto a dust-
`free concrete surface. The surface can be
`rough or smooth, moist or dry.
`Application Method for 10.5 oz. Cartridges:
`Break the moisture proofing aluminum foil on
`the top of the cartridge and remove the plug
`from the bottom. Screw on the nozzle and
`
`
`cut diagonally at the appropriate position.
`Place the cartridge into the caulking gun.
`For 20oz. Sausages: Put the sausage in the
`empty tube of the bulk caulking gun and cut
`1/8 inch off the top of the sausage. Close the
`tube and install the nozzle. Nozzles are
`supplied with
`the appropriate opening.
`Swellseal® WA must be applied
`in an
`uninterrupted band (minimum 3/8 inch wide
`and thick), gunned in the middle of the joint or
`prefab element. Concrete cover should be at
`least 3 inches on both sides, in order to avoid
`cracks from the pressure of material swelling.
`If Swellseal® WA is to be installation under
`water or during heavy rain the concrete
`operation should begin within 2 hours of
`application to provide confinement for the
`material or premature swelling may result
`lowering the effectiveness of the material.
`
`STORAGE & HANDLING
`Store in dry area for up to 12 months from
`date of production at temperatures between
`40°F and 85°F for best performance. See shelf
`life details on the material packaging.
`
`PRECAUTIONS
`Always use protective clothing, gloves and
`goggles consistent with OSHA regulations
`during use. Avoid eye and skin contact. Do not
`ingest. Refer to Material Safety Data Sheet for
`detailed safety precautions.
