Features

  • The average Kiwi fence stands between 1.2m - 1.8m high supported by 100mm x 100mm H4 posts. This product is for posts up to 1.2m high
  • Cemix recommends 2 x 20kg bags per post
  • No mixing required - just pour product in the hole containing the recommended water
  • 15 minute set time
  • Typical Uses: Letter Box Signs, small signs, low fence posts and temporary hold posts before topping with general purpose cement or Maxcrete.
CEMIX FASTCRETE Post Hole Concrete is designed specifically for concreting in posts. It consists of a uniformly blended and
proportioned mixture of sands, aggregates, Portland cement and admixtures, designed to improve the concretes
performance. The bags are simply poured gently in to a post hole containing the correct amount of water. CEMIX FASTCRETE
Post Hole Concrete is designed to attain a compressive strength of 15MPa after 28 days.

SUITABLE PROJECTS:
• Residential fence posts
• Letter box posts
• Small sign posts
• Small clothes lines
• Non-structural decking posts

LIMITATIONS:
CEMIX FASTCRETE Post Hole Concrete will reach a compressive strength of 15MPa after 28 days making it suitable for
non-structural work. In general, structural work requires a minimum of 17.5MPa. For all structural applications and any heavy
duty post work such as sun shades or posts in high wind zones, CEMIX SUPER STRENGTH FASTCRETE Post Hole Concrete
must instead be used.

CEMIX SUPER STRENGTH FASTCRETE Post Hole Concrete will attain a compressive strength of 30MPa
after 28 days.

For applications requiring a barrow mixed concrete with workability and longer set times, use either of CEMIX MULTICRETE or
CEMIX MAXCRETE which will attain 28 day compressive strengths of 28MPa and 45MPa respectively.
