Post support bases are made to suit common square timber posts such as 70×70, 90×90 and 100×100 mm, with round-post and dowel versions also available. Match the base to your post section so it seats correctly, and note that square, round and dowelling styles differ in how the post connects.

Yes, post support bases and post shoes are typically pressed from galvanised steel to resist corrosion in outdoor, ground-level conditions. The zinc coating protects the base against moisture where the post meets concrete or paving, extending the life of fences, decks and pergolas.

A bolt-down post support base is fixed by anchoring its flat plate to a cured concrete slab or foundation with expansion or anchor bolts through the pre-drilled holes, then fitting the timber post into the cradle and screwing through the side holes. Ensure the concrete is fully set and the base is level before mounting the post.

A repair spur is a concrete or steel post support used to reinforce or replace the rotted base of an existing timber post without removing the whole post. It is concreted in or bolted alongside the failing post and fixed to the sound timber above the damage. The GeZu Impex range includes square, round and dowelling bases plus repair spurs, with each listing showing the post size it suits.
