Sika Grout-212 NZ is a high strength, shrinkage-compensated cementitious grout for filling confined, restrained gaps between 6mm and 80mm. Structural engineers and precasters specify Sika Grout-212 for base plate and machine foundation grouting, anchor bolts, ground anchors, and reinforcement ducts in precast column-beam connections, where any shrinkage gap between substrate and structure compromises load transfer. A blend of natural aggregates and Sika admixtures gives the grout a two-stage cure: slight expansion while curing, then shrinkage compensation once hardened, keeping full contact between the grout and the surrounding concrete and steel. On site, the grout mixes with clean water alone, 4.5 litres per 25kg bag, for 2-3 minutes on a low-speed drill, and pours at a CRD cone flow of around 60 seconds for tight, void-free filling. A 25kg bag yields roughly 13.5 litres, reaching 20MPa within 24 hours and 65MPa at 28 days. Concreters and civil contractors use Sika Grout-212 across machine bases, precast connections, and anchor grouting on commercial and industrial builds throughout New Zealand.

About Sika Grout - 212 NZ 25kg
Sika Grout-212 NZ fills confined, restrained gaps between 6mm and 80mm under machine base plates, structural steelwork, anchor bolts, and precast connections. The shrinkage-compensated cementitious grout mixes with water on site and pours into place to keep full contact between a structure and its foundation.
Sika Grout-212 NZ takes a maximum of 4.5 litres of clean water per 25kg bag. Mix for 2-3 minutes with a low-speed drill running at a maximum of 500rpm until the grout is smooth and free of lumps, then pour immediately.
Sika Grout-212 NZ reaches 20MPa compressive strength within 24 hours, 55MPa at 7 days, and 65MPa at 28 days. Formwork should stay in place for at least 5 days to control moisture loss and provide restraint while the grout expands.
Yes, Sika Grout-212 NZ is shrinkage-compensated. The grout expands slightly during curing and compensates for shrinkage once hardened, so contact is maintained between the base plate or anchor and the surrounding concrete.
Sika Grout-212 NZ fills gaps from 6mm up to 80mm in a single pour. Formwork or the surrounding structure needs to confine and restrain the grout during placement and curing to get the full shrinkage-compensation benefit.
Sika Grout-212 NZ should be applied at substrate and ambient temperatures between +5°C and +25°C. Outside this range, set times and strength development will differ from the published technical data.
A 25kg bag of Sika Grout-212 NZ yields approximately 13.5 litres of mixed, pourable grout when combined with 4.5 litres of water. Confirm the void volume before ordering to make sure one continuous pour is possible.
