Further information

Postmix is specially designed and formulated to make fixing posts quick and easy. The factory blended, high quality concrete is the ideal solution for all post erecting applications.

Postmix is specifically designed for securing fence posts (concrete, timber, metal and plastic), gates, washing line poles, rotary washing lines, fence support posts, bird tables / feeders, children’s play equipment, etc.

Technical information

Typical Application Technique

Firstly, dig the hole. The recommended depth of the hole depends on the height of  the post, the load it will support and the soil conditions. As a guide a 75mm (3”) square post 1.5m high should be 46cm (18”) in  heavy soil or 60cm (24”) in light soil orexposed position. The soil in the base should be firm. Insert the post.

MIXING INSTRUCTIONS

1. Add approximately 5 litres of clean water for every bag used. Pour the half the bag of Postmix into the posthole around the post. Add approximately 2½ litres of clean water allowing the water to penetrate the mix.

2. Check and if necessary adjust the vertical position of the post. Place the remaining material into the hole, followed by a further 2½ litres of clean water. Recommended ambient application temperature is 5oC to 25oC. Do not use when air temperature is below 5oC or when ground is frozen.

TYPICAL PERFORMANCE

Initial set time: 5-10 minutes depending on conditions

Typical compressive strength at 28 days is 28N/mm2 (20oC)

PACKAGING & STORAGE

Postmix is available in nominal 20kg plastic waterproof sacks, palletised and shrink wrapped. Palletised Postset can be stored internally or externally on firm level ground. Shelf life is 12 months subject to temperature and humidity.
