Single component hydrophilic waterstop for sealing construction joints and pipe penetrations
CSI Div. 03
03 15 13.16 Expanding Waterstops
Waterstop-GunGrade is a single component hydrophilic waterstop,
designed for sealing smooth to very irregular construction joints and pipe
penetrations. It cures and swells in the presence of moisture or water.
Curing time depends on temperature and humidity, for example cure time
decreases when temperature and RH are higher. Waterstop-GunGrade
cures 24-36 hours. Waterstop-GunGrade is available in cartridges and
Any concrete structure with larger volume water leaks such as:
• Sealing rough and smooth construction joints of cast in-place or precast
concrete in wet and underwater applications.
• Sealing joints in pre-cast segments in wet or underwater applications
such as manholes, box culverts, cable ducts and pipes.
• Sealing joints between sheet piles.
• Excellent adhesion to concrete, PVC, HDPE, steel, & fiberglass
• Can be applied to wet surfaces or underwater when concrete is poured
within 2 hours
• Adapts to irregular surfaces
• Expands to more than 200% of original cured volume
• Easy application with standard caulking guns
• Solvent free
Concrete substrate must be dust-free and no lose debris. The surface can
be rough or smooth, damp or dry.
• 10 oz. Cartridges: Use a heavy duty single cartridge gun. Screw on the
nozzle and cut diagonally at the appropriate position
• 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.
• Waterstop-GunGrade must be applied in an uninterrupted band
(minimum 3/8” bead), gunned in the middle of the joint or precast
• Concrete cover must be minumum 3” inches on all sides, in order to
avoid cracks from the pressure of material swelling.
• If installing Waterstop-GunGrade under water or during heavy rain,
concrete placement must begin within 2 hours of application to provide
confinement for the material and prevent potential premature swelling,
which can lower effectiveness of the material.

Storage & Shelf Life:
12 months when stored properly. Product is highly moisture sensitive. Store
in original sealed containers at temperature between 60°F – 90°F.
• Waterstop-GunGrade must be fully confined on all sides to perform
properly. When used in precast or joints, minimum concrete cover is 3”
on all sides. Unconfined material may expand greater than 200% and
develop an open celled structure, resulting in leaks.
• Not suitable for surface caulking applications.
• Not recommended for application at temperatures below 40ºF as
material can have very long cure times (exceeding several days).
Proper application is the responsibility of the user. Field visits by AQUAFIN
personnel are for the purpose of making technical recommendations and
not for supervising or providing quality control on-site.
