Measure the full width and depth of the finished pillar, including any render or facing brick. Allow for a slight overhang on each side, typically 25–50mm, to help water run clear of the masonry below.
Decorative & Weatherproof Pillar Caps for Garden Walls
Pillar caps provide a practical and decorative finishing touch to brick and blockwork piers. Designed to sit securely on top of gate posts, entrance pillars and boundary walls, they help protect masonry from rain penetration and frost damage while improving the overall appearance of an outdoor space. Available in a range of sizes, these concrete pillar caps are suitable for both new builds and refurbishment projects where long-term weather protection is required.
Manufactured from durable concrete, pillar caps are built to withstand the UK climate and reduce the risk of water tracking down into mortar joints. When paired with Wall Copings, they create a consistent finish across garden walls and perimeter boundaries, helping to direct water away from vertical surfaces. Installation typically involves bedding the cap onto a suitable mortar mix or exterior grade adhesive, ensuring even coverage and correct overhang to shed water effectively. Accurate measurement of the pillar footprint is important to achieve a secure fit and balanced appearance.
Pillar caps are commonly used alongside materials found in Concrete Blocks and Facing Bricks, forming part of a complete walling system that combines strength with visual detail. They are compatible with standard masonry construction methods and can be pointed to match surrounding brickwork for a seamless finish. By limiting moisture ingress, they help prolong the life of structural pillars and reduce maintenance requirements over time, making them a practical addition to gates, driveways and garden boundaries.
Pillar Cap FAQ's
They are usually bedded on a strong sand and cement mortar mix. The top of the pillar should be clean and level before application, and excess mortar should be removed once positioned. Some installations may use exterior construction adhesive for additional bonding.
Yes, a small overhang is recommended to ensure rainwater drips away from the wall surface rather than running down it, which helps reduce staining and damp issues.
They can be fitted to rendered pillars as long as the surface is sound and level. It is important to ensure a stable base so the cap sits evenly and remains secure.
Concrete pillar caps are designed for outdoor use and can withstand typical UK weather conditions. Proper installation and pointing help prevent water ingress and extend the life of the pillar beneath.
