About our Wetcast Concrete Slotted Post Our Wetcast Concrete Slotted Fence Post dry to a smooth white finish. Produced from 10mm gravel aggregate, concreting sand, and high-performance cement, delivering a strength of 45-50 N/mm². We actually reinforce each post with four 5.5mm carbon steel re-bars whilst plastic spacers to maintain a 25mm concrete cover. Matching as well as contrasting gravels boards are also available below. Our Rapid Set Post Mix is also ideal for securing concrete posts. You can find it in Fencing Accessories, but also by clicking HERE. The best way to fix our Wetcast Posts Dig a hole to the correct depth as well as width, relevant to post size. Fill hole approximately a third of depth with water and place post in the hole. Pour in Carlton FP-ECOFIX evenly around the post until no standing water is visible. Position and level post as required. Setting will take place in 5 to 10 minutes. Do not mix Carlton FP-ECOFIX with water by hand or machine.
