Cemix Fastcrete – 20kg

Cemix Fastcrete is a fast-setting bagged concrete built for post hole applications, reaching 20MPa compressive strength after 28 days when used to the manufacturer’s recommendations. Standard concrete takes hours to set enough to hold a post steady, and that wait holds up fencing, deck post, and letterbox jobs where the post needs to stay plumb after backfilling. Fastcrete is a pre-mixed blend of sands, aggregates, Portland cement, and admixtures formulated to set quickly on contact with moisture. It’s supplied in a 20kg bag. Fencing contractors, landscapers, and builders use it to set fence posts, deck posts, and similar structures without a lengthy standing time.
