Fast-Setting Cement Post Fix for Secure Fencing & Uprights
When installing fence posts, rotary airers, pergolas, or gate posts, speed and durability are essential. Standard concrete mixes can take up to 24 to 48 hours to fully set, leaving your posts vulnerable to movement and delaying your project. Our range of post fix solutions is engineered for rapid setting, reaching initial set times in as little as 5 to 10 minutes.
By eliminating the need to pre-mix in a bucket or cement mixer, cement post fix simplifies installation and saves valuable time, labour, and effort on site.
Key Advantages of Using Post Fix Concrete
- No Pre-Mixing Required: Pour directly from the bag into the hole, add clean water, and wait for it to set.
- Rapid Set Times: Fixes posts firmly within minutes so you can continue installing fence panels and rails without long waiting periods.
- Versatile Application: Suitable for securing wooden, concrete, metal, and plastic posts in earth, gravel, or existing masonry foundations.
- Weather-Resistant Durability: Formulated to withstand harsh UK weather conditions, freeze-thaw cycles, and ground moisture without cracking or weakening.
How to Use Post Fix Concrete in 4 Easy Steps
- Dig the Hole: Dig a post hole to the required depth and width (typically about three times the post diameter and a third of its total length).
- Position the Post: Position your post upright into the hole, using a spirit level to ensure it is completely vertical. Use temporary timber props to hold it steady if needed.
- Pour the Post Fix: Fill the hole roughly halfway with clean water, then pour the dry post fix mix evenly around the post until no standing water remains on the surface.
- Allow to Set: The cement post fix will begin to react immediately. Tap the surface gently to release trapped air bubbles and leave it undisturbed while it cures.
