K Rend K Post is a rapid-setting concrete mix formulated for securing metal, wood, and concrete posts into the ground. This pre-blended material is typically utilised for fencing installations, decking supports, and outdoor signage where fast positioning is required.
The application process requires no manual mixing. To secure a post, a hole is excavated to the required dimensions and filled halfway with clean water before the post is positioned. The dry mixture is then poured directly from the bag evenly around the post to fill the cavity. Tapping the setting surface helps remove trapped air bubbles before covering with soil. This rapid-setting formula achieves an initial set within 5-10 minutes.
This concrete mix features cement replacement technology, which yields a 34% reduction in embodied carbon compared to standard grey cement-based post-fixing products, equating to a saving of 56kg of CO2 per tonne. The product is supplied in 20kg showerproof, non-slip sacks, allowing for weather-resistant storage directly on-site without additional covers. It is suitable for application in temperatures between 5°C and 30°C.
- Sets within 5-10 minutes to accelerate post installation timelines.
- Requires no pre-mixing or measuring as it is applied straight from the bag.
- Formulated for fixing wood, metal, and concrete posts into excavated holes.
- Carbon emissions are reduced by 34% using cement replacement technology.
- Supplied in 20kg showerproof bags for weather resistant on-site storage.
