Dig the holes for your stumps using the marks you made with string lines, which we covered in another video. The holes must be dug to depths according to your plans and permits. The sides of the holes must be straight and clean at the top.
After your bearers are cut to size, you'll need to join two together. Run a bead of glue down the length of one bearer. Place it on top of the other bearer and line them up so they're flush. Use the nail gun to join the two bearers. Make sure the nails go in on a slight angle, as this will give them better holding power. Turn the bearers over and nail the other side as well.
Use the check-out measurement you made and mark it on the end of a bearer. Make sure you also use a set square to mark the depth and length of the check-out. This check-out will give your decking extra support over the brickwork.
Use the circular saw to cut along the length of the bearer check-out. Then to cut across the bearer. Make sure you set the correct depth on your circular saw so you don't overcut your markings. Use a hammer to remove the check-out from the bearer. Then use the chisel to make it level.
Place the bearer on the brickwork. At the other end of the bearer, place a support post on a flat, hard surface. Making sure the bearer is level, mark its height on the support post. Use the nail gun to secure the bearer to the support post. Place another support post on the other side of the bearer and secure it with the nail gun. Use the spirit level to make sure it's still straight.
Put ant capping on top of the stump and then have someone help you insert the stumps into the holes. Lift the stump so the threaded rod goes through the hole in the bearer. Place a washer and nut onto the rod and tighten with a spanner to securely suspend your stump. Check that the bearer is still level after you've attached the stump.
Mix the concrete in a wheelbarrow. Then fill in your hole with concrete around the stumps up to the required height.
Now repeat the previous steps to join, install and secure the other bearers and stumps for every hole that you've dug.
You'll need to leave the concrete around the stumps to harden overnight. Then use a claw hammer to remove all of the support posts on the bearers. Back-fill all of the holes with soil. Then you can tidy up your work site and you're ready to install your joists.
