SHRINKKOMP 20
A free-flow hydraulic grout poured rather than trowelled, at 13–15% water for flowable consistency and 3 mm maximum grain. It expands slightly instead of shrinking — 0.15–0.2% free, 0.05–0.12% restrained — which is what keeps a baseplate in full bearing contact. Compressive strength runs 100–220 kg/cm² at 24 hours to 500–550 at 28 days. 50 kg bags.
