How to build a Gazebo

Mixing ConcreteA mixture of sand, gravel, water and cement which hardens to a stone like condition when dry. & Standing Posts

Mixing the concrete

In a wheelbarrow or concrete mixer, make a mix consisting of 5 parts gravel and sand mix, to one part cementA powdery type substance made from a mixture of earths materials such as limestone and shale, which is sintered (cause to become solid mass by heating without melting), ground, and mixed with small amounts of calcium sulphate and calcium carbonate. Cement is activated by water and when mixed with gravel and sand, forms concrete..
Pour in clean water and mix to a uniform consistency with a spade or shovel. The mix should be stiff enough to hold up the posts without bracing props yet wet enough to work around the posts.

Standing up the posts

This will take two people. One to hold the postsee PILE and one to shovel the concrete into the hole.
First shovel some concrete into the hole so there is at least a 3″ (75mm) concrete base under the bottom end of the post. Place a post into the hole so it sits against the end of the template boardA piece of sawn, or dressed lumber of greater width than thickness. Usually 19mm (3/4") to 38mm (1 1/2") thick and 75mm (3") or more wide. (fig 3) and ensure post is plumbVertical; Upright. or verticalPlumb, upright. by way of holding a spirit levelTool used to ensure surfaces are level or plumb by means of a bubble in a tube of liquid fitted to the level. against two adjacent sides of the post.

Fill the hole with concrete and check again that the posts are plumb. Because of the depth of the hole and the stiffness of the concrete, the post will stay up by itself. Of course you will need a calm day! Repeat this procedure until all posts are in concrete, in place and standing plumb/vertical. Check again an hour later.

Well, that’s all you can do today so you may as well go inside and watch your favorite sport on TV.
