Rapid Set 20KG

A fast-setting concrete mix that begins hardening in 15 minutes so you can get the job done and move on.

Rapid Set Concrete is a pre-blended mix of cement, sand, and aggregate that delivers reliable structural strength without the wait of standard concrete. For post holes, simply place the post, pour the dry mix around it, add water, and hold it plumb for 10 to 15 minutes. For general applications, mix with approximately 2 to 2.5 litres of water per 20kg bag and place within 5 to 10 minutes of mixing.

One 20kg bag covers approximately 0.01 cubic metres, with one standard post hole typically requiring 1 to 1.5 bags depending on hole diameter and depth.
