The GeZu Impex post base sleeves are designed for homeowners and contractors looking for a secure way to anchor square timber posts to concrete foundations for fences and pergolas. They offer excellent structural stability and moisture protection through their raised sleeve design, though they are specifically engineered for timber constructions up to 1.5 meters in height. These heavy-duty grey brackets simplify installation with pre-drilled holes, ensuring your landscaping projects remain level and durable against the elements.

These brackets are designed for timber constructions up to 1.5 meters in height. Using them for taller structures may compromise safety and stability.
The pre-drilled holes are 11 mm in diameter; therefore, you should use anchor bolts or dowels compatible with an 11 mm hole for a secure fit.
No. The sleeve is designed to keep the post elevated above the base plate to ensure air circulation and prevent moisture damage.
The product includes the brackets themselves; you will need to purchase concrete anchors and wood screws separately based on your specific site conditions.
While the finish is durable for general landscaping, coastal areas with high salt content may require additional protective coatings or stainless steel hardware to prevent oxidation over time.
Verify that all 8 base plate bolts are fully tightened and that the timber post is screwed firmly into the sides of the sleeve.
Check if the timber is damp or swollen; you may need to sand or plane the bottom of the post slightly for a better fit.
To install, position the bracket on your concrete foundation and mark the eight holes through the base plate. Use a masonry drill bit to create holes in the concrete, then secure the bracket using appropriate heavy-duty expansion bolts or anchor dowels. Slide your timber post into the sleeve and fasten it using screws through the side of the sleeve. To maintain the integrity of the bracket, inspect it periodically after extreme weather. Ensure that the gap between the post and the concrete base remains clear of debris to allow for continued ventilation.
