Pourable, cement-based, non-shrinking, quick-setting anchoring cement. SpecRock is a high-performance, one-component, waterproof, non-shrink, Portland cement-based anchoring cement. It sets hard within 12-15 minutes and exhibits controlled expansion, effectively locking into surrounding concrete. SpecRock ES (Extended Set) offers a longer set time of 60-75 minutes, ideal for hot weather conditions above 90°F, providing more flexibility during application.
