Polypaste
PolyPaste is a high quality, one component polyurethane adhesive which swells in contact with water. Upon contact with water, the paste can expand up to 450% of its original volume and creates a positive pressure against the faces of the concrete joint, thus preventing the passage of water.
AREA OF USE
-
Filling in and repairing cracks
-
Construction joints
-
Can be used as an adhesive for bonding SwellPro strips or as a problem-solving hydrophilic waterstop in difficult access areas including:
-
Sealing around joints in precast manhole covers, cable ducts and pipes, etc
-
Sealing around precast segments
-
Sealing between rough surfaces, e.g. slurry walls and concrete slabs
-
Sealing around H-beams and other penetrations through concrete structures
-
Sealing around conventional rubber and plastic waterstops to provide ‘belt and braces’ seal prior to concrete pour
ADVANTAGES
-
High quality, water swellable one component polyurethane adhesive
-
Excellent seal on rough concrete
-
Gives improved water tightness
-
Plugs inequalities in rough concrete to produce a tight seal
-
Excellent adhesion
-
Quick and easy to apply to a variety of uneven joint surfaces remaining firmly in place during concrete pour
-
Expands by 450% producing a watertight compression seal
-
Excellent wet/dry cycling retaining elastomeric character and swelling performance due to high tolerance of the cementitious environment
