RapidSet® instant post hole structural concrete is dry bagged premixed concrete with special additives that will make the concrete set in 15 minutes (at 21o Celsius) when added to water. However, warmer outside temperatures (summer) means a faster set time, colder temperatures (winter) means a slower set time.

RapidSet® bagged concrete will reach 20MPa after 28 days and is suitable for structural projects such as deck posts and non structural projects such as fence posts.

AVAILABLE IN: 25kg bags

  • No bracing - just hold the post in position for a few minutes and RapidSet will go to work
  • RapidSet will set in 15 minutes
  • After one hour it will have gained significant strength to enable you to carry on working (e.g fixing rails), as long as the area is not exposed to rigorous use
  • No mess - no leftover sand, cement and stones to clear away. What you don’t use stays in the bag
  • No mixing - just pour water into the hole and slowly pour RapidSet straight into the hole
  • Long term concrete expansion is minimised through use of advanced fast set technology
  • RapidSet is formulated to reach a target strength of 20MPa after 28 days (under standard curing conditions)
