Sika Grout – 212 NZ 25kg

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.
