We manufacturer a range of morticed concrete posts for timber closeboard fencing with gravel boards to suit various fence heights. Fittings are also available.
A mortice is a is a rectangular cavity in a material that usually forms a joint. In fencing, timber arris rails are fitted through the mortice. Feather-edge boards are then nailed to the arris rail and overlap each other to create a continuous barrier. Also known as closeboard fencing, this is an attractive method of fencing, which provides complete privacy.

Morticed concrete fence posts are among the most durable and dependable fencing options for both residential and commercial properties. Crafted to securely support fence panels and gravel boards, these robust concrete posts deliver superior strength, stability, and long-term performance.
Unlike traditional wooden posts, they resist rotting, warping, and insect damage, making them a low-maintenance solution that withstands harsh weather conditions over time. Their slotted design facilitates quick and easy installation, and allows for simple replacement of damaged panels without removing the posts.
Whether installing a new garden fence or upgrading existing wooden posts, morticed concrete fence posts provide exceptional durability, enhanced security, and great value, making them the top choice for homeowners, landscapers and fencing professionals.

All of posts are available either with a round top or a pyramid top. The choice is a personal one but we find the round top posts are the more popular.
Corner morticed fence posts are available to allow for a change of direction at 90° angles.
A concrete gravel board is used to prevent the timber coming in contact with the ground, preventing rotting.

Wooden fence posts are susceptible to rot, insect damage, and weather-related wear and tear. Despite being treated, they can still weaken over time, particularly if they’re in contact with damp soil. If a wooden post becomes damaged, there’s a high chance that the attached fence panels will suffer damage too, meaning you’ll need to replace both a fence post and possibly two fence panels.
Concrete fence posts, on the other hand, are far more durable. They don’t rot, are resistant to weather damage, and can last for decades with minimal maintenance. When combined with concrete gravel boards, your fence panels are lifted off the ground, reducing their exposure to moisture and extending their lifespan even further.
