Bolt-Down Supports and Metal Spike Supports

When erecting posts on a solid level surface, such as paving, use bolt-down, galvanized metal plates. These can be fixed in place relatively easily and will help to prolong the life of the wood posts by holding them off the ground.

Measure and mark the exact position of the post. Take good care to do this right, even if it takes more than once; you can't change the positions of posts once they're secured in bolt-downs. Position the base plate, marking the position of each of the corner bolt holes with a pencil (image 1).

Use a percussion or hammer drill fitted with a masonry bit to drill the bolt holes. Keep the drill upright and make sure you penetrate right through the paving into the graded base underneath (image 2).

Fill the drilled holes with mortar injection resin and insert Rawl bolts. After the recommended setting time, tighten the bolts using a wrench — the bolts will expand to fill the hole (image 3).

If you have firm, undisturbed ground, use metal spike supports. Position the spike in place and insert a "dolly," a special post-driver, into the square cup. Hit the dolly with a mallet to drive the spike into the ground. Check the angle of the spike with a level (image 4) to ensure that it is going in straight — twist the dolly handles to correct any misalignment. When the spike is in the ground, remove the dolly. Clamp the square cup around the post and tighten it up.
