Instant Grout

Five Star Instant Grout is a rapid strength gain, nonmetallic, nonshrink grout for supporting machinery requiring precision alignment and quick turnaround. It is formulated with an advanced technology ideal for cold weather applications, while providing the greatest reliability, and selective chemical resistance. When tested in accordance with ASTM C 827, Five Star Instant Grout shows positive expansion. Five Star Instant Grout meets the performance requirements of ASTM C 1107-02 and CRD-C 621-93 specifications for nonshrink grout.
